See how Microsoft’s TFS Agile Team do their scrum stand-up and parking lot meetings Short video is the stand-up – Long video is the parking lot meeting.
I like the use of the Agile Board it is a nice visual that is missing in the standard stand-up meetings in most companies.

On occasion when I open a Web application in Visual Studio, I receive a message that is similar to the following:
So that the search bots can find the text, the pertinent portion reads “The following settings were applied to the project based on settings for the local instance of IIS Express”.
The message basically says that the settings on the Web application with respect to authentication don’t match the default settings in your local IIS Express. So Visual Studio, to make sure that the project can be deployed, changes the Web application settings. Now there are many cases where this is not desirable and the message nicely tells you how to change it back. What is hard to find out is how to change the default settings for IIS Express.
If you go through the “normal” steps, your first thought might be to check out IIS Express itself. But even if you change the settings for the Default Web Site (or any other Web Site you have defined), that’s not good enough.
Instead, you need to modify the ApplicationHost.Config file. You will find it in your My Documents directory under IISExpress/Config. In that file, there is an <authentication> section that determines whether each of the different authentication providers is enabled or disabled. If you modify this file to match your Web application’s requirements, you will no longer get that annoying dialog box popping every time your load your Solution. Of course, you *might* have to changed it for different projects, that’s just the way it goes.
Some of you might not be aware of it, but one of the premier development conferences is coming to Toronto in a few weeks (May 27-31). That conference would be DevTeach.
For the past 10 years, DevTeach has been bringing some of the best speakers from North America to Canada to talk about the thing that we’re most passionate about: development. You will hear topics covering a wide ranges of subjects, from Agile to Cloud, Mobile to Web development, SharePoint to SQL Server. If you are interested in hearing some of the most engaging and knowledgeable speakers, then DevTeach is the place to be.
In an earlier blog post, I mentioned that ObjectSharp will be out in force for the conference. Since then, we have added more speakers to the roster. Max Yermakhanov will be speaking on Hybrid Cloud and Daniel Crenna expounds on globalization in Web applications. Max is ObjectSharp’s resident IT guru. He is responsible for the fact that ObjectSharp’s infrastructure is as cloud-y as it can be. So he brings with him real-world experience related to seamlessly weaving Azure and on premise infrastructure.
Daniel is relatively new to ObjectSharp but not to the world of .NET. A former Microsoft MVP, he is responsible for a number of open source projects, including TweetSharp. His session on globalization in Web development will touch on the stuff that only comes up when you’ve gone through the crucible of actual implementation. And being in Canada, it comes up quite frequently.
ObjectSharp has been a sponsor and champion for DevTeach since its very early days. This year, the timing of the conference would have conflicted with our annual At the Movies event. So we put off At the Movies for a year. Because that’s how good this conference is.
So if you have been to one of our At The Movies events in the past, then I strongly suggest you look at DevTeach instead. Don’t worry…we’ll go back to doing At The Movies next year (it’s too much fun for us to stop). But until then, DevTeach is the place you should be at to hear the latest and greatest in development talks.
As I write this blog entry, I’m flying to Atlanta to give the last of 13 seminars on the new App model that is available for Office 2013 and SharePoint 2013. I have taught this material to people all over North America, as well as in Paris. As a result, I have talked to a large number of people not only about the model, but also about their plans for it. This gives me a fairly unique perspective into how people are taking the new model, as well as how it will be adopted over the next 6-9 months.
What is “The New App Model”
What’s the Benefit?
Well for the Apps for Office model, the benefit is that you don’t have to wrestle with VSTO or MSIs to be able to deploy your applications. There is (more or less) no administrative permissions required to install an application. And there is now an Office Store where users can search for and install your application. So your ability to reach more potential clients is much higher.
For the Apps for SharePoint model, there is no need for sandbox solutions. This is not to say that you still can’t write sandbox (or farm) solutions. You can. And they still have all of the same limitations that those applications had in SharePoint 2010. But the guidance is that they should no longer be needed. The client side object model (CSOM) has been expanded to the point where farm solutions are probably not required. And if you are working in a shared hosting environment (that’s everyone is SharePoint Online, as well as a number of clients of ours), then you can be freed from the limitations of the sandbox.
And What are the Problems?
The biggest problem is that, because the model is completely new, there is no compatibility with older versions of the products. This model will not work with Office 2010 or SharePoint 2010. At all. No way, no how. If you understand the details of what’s going on, you’ll understand why this limitation exists. But the practical impact is that your only audience for any app you write and want to sell is new users. In the corporate world, this could be a few years off. For SharePoint Online, it’s a little closer, as the back-end functionality is in the process of being converted, with the user interface to be upgraded over the next 12-18 month.
Along with the need to have users on the latest version, the capability of the interface with the software seems to be a little lacking in certain areas. I found this to be particularly true in the Apps for Office model. A number of people had interesting ideas for Word or Excel applications and their first choice for a user experience ran aground on the shoals of missing capabilities. For instance, there is no way to retrieve or modify the format for a particular cell. Nor is there the ability to have the app set the currently selected cell. Is this a critical lack of functionality? Possibility. But I also know a number of people who are on the development team and they are eager to address holes in the functionality, especially if there is a compelling story around the request.
Is It Worth Using?
I think that quick answer is ‘yes’. Now it could be that I’m biased…I have been teaching this material for a while. But I like to think that talking to people about the model, hearing what they want to do and working through how it might be done has given me perspective. And I don’t have a history of liking a technology just because I teach it.
Again, dividing between Office and SharePoint, I believe that app model for SharePoint will be transformative. In particular, if you have a Web-based application that has nothing whatsoever to do with SharePoint, it is simple to integrate the application with SharePoint. And put it into the SharePoint Store, increasing its visibility. The model also requires that people who create SharePoint applications need to rethink their approach. Instead of being forced to utilize SharePoint as a data store (a task for which is it not particularly well suited), you can use a real database. Yea!!!!
The app model for Office is a good one in cases where it fits. At the moment, that seems to be helper applications. Dictionaries, encyclopedias, image searching. Maybe an application that can perform calculations based on the data in the document. But at the moment, there do seem to be some pieces of functionality that I’d like to see put in place. And the model is so different from how users typically use Word/Excel that I can see it taking a little bit of time to see mass acceptance.
If you have any experience with the app model, either with Office or SharePoint, I’d like to hear how it went. What type of applications have you created? Was there missing functionality that you had to work around? I’m done with the teaching tour, but I’d still like to keep in touch with how people use the model.
If you are an aficionado of conferences, then odds are pretty good that you have already aware that DevTeach is coming to Toronto at the end of May (May 27-31, to be precise). If you have not attended, heard of or thought about DevTeach, then you’re in for a treat.
DevTeach is a conference. For developers. By developers. If you want to learn about the latest technology, then DevTeach is the place to be. This is true whether you are interesting in developing apps, using and administering SQL Server, or working with the latest mobile technology. You will hear from industry experts, people from not only all over North America, but also locals you can chat with afterwards. And when it comes to networking, there are few conferences that offer the opportunity to hang with as many of the best and brightest.
At ObjectSharp, we are proud to be a supporter of DevTeach. And we are lucky enough to have a list of associates who are knowledgeable enough to be able (and generous enough to be willing) to share their insights and experience with others. The following is a list of the sessions that are led by one of our own. If this list isn’t enough to entice you, then check out the full schedule here. Or you can just trust me and sign up here. Take advantage of the fact that all of this talent is within your reach to hear from and talk to.

One option in Test Manager for Test Suite is “Add Requirement” which adds the Requirement ID and it’s title as a test suite. Example below:
What happens if at a later date someone goes in and changes the title of the PBI?
First the change in the work item to the title does not show in your Test Suite. What has been added to Test Manager is an object on it’s own not a link to the actual work item. Think of it as a folder for tests related to your requirement.
What can I do?
There is the delete/add option however you will lose all test results associated to your test suite. When you delete a suite all test points contained within the suite are deleted. I would only use this when test execution has not happened yet for the test suite.
The rename option on a test suite can be used. Select test suite > right-click > Rename. In this option I would copy from the actual work item so the titles match.
How do you know there has been a change?
Often you don’t without someone telling you or finding by accident or creating a query to compare with. I’d like an alert that tells me when a Requirement title has changed and the Iteration Path. Both of these can affect the Test Plans and their Suites.
This happens in both MTM2010 and MTM2012.
For most people, the idea of writing a book is a daunting one. There is little that scares people more than a blank page and the need to put 10,000 words onto it in the next 30 days or so. I believe that death and public speaking might be higher on the list, but only by a little. So the gumption it takes to put together a book proposal, submit it to a publisher, write all of those words, suffer with editors and technical editors making comments and finally get to the point where it’s it published is a big deal. For that reason, I’d like to celebrate two of my ObjectSharp colleagues, Lori Lalonde (@LoriBLalonde) and David Totzke (@VisualDragon) who now have a publication date for their book, Windows Phone 8 Recipes.
I know that it’s a thankless journey, but allow me to offer up my appreciation for your contribution to the world of technical literature. As for the rest of you, you can show your appreciation by going here and buying a copy. It is currently on pre-order with a scheduled publication date of June 26th, but you can buy an alpha copy of the book and get access to the wonders that are inside right now.
Hopefully most, if not all, of you will be aware of the AppFests that ObjectSharp ran in conjunction with Microsoft between September and December of last year. If you had the joy of attending, you would definitely be aware that by submitting apps to either the Windows Phone Marketplace or the Windows Store, you would have a chance to win either a Surface RT or a Nokia Lumia 920. Well, it has taken a while to get the submission information (and thanks to Jonathan Rozenblit for his help), but we have gathered up all of the apps that were submitted, calculated the entries and found our winners. They are as follows:
Surface RT Winner: Tom Walker (Orange Crush)
Tom submitted nine apps and the following is one of his better reviewed ones
Short Cuts - Life is to short to waste time trying to find your phone settings. Short Cuts enables the user to quickly access their phones wifi, bluetooth, airplane mode and cellular settings
Nokia Lumia 920 winner: Gordon Lo (13 Sides)
Gordon submitted a total of 8 apps and the following app received 4 stars over 17 reviews
My Business Card - My Business Card is a simple, fast, and lightweight way to share your contact information using a QR Code. This app encodes it as a MeCard that is compatible with virtually all QR Code scanners out there. Share quickly, and share easily with My Business Card.
Finally, just so you have a sense of the volume of apps produced through the AppFest engine :), we recorded a total of 107 Windows Phone apps and 49 Windows Store apps. Not bad, but I know you can do better. If you check out the Developer Movement web site (http://www.developermovement.ca), you can see how to sign up, submit your apps and win some cool prizes.
I will profile a number of the other apps that were created through the AppFest process over the next few blog posts. If you’d like to receive some publicity for apps that you have built, feel free to drop me an email with a link to your store or marketplace page.
At one of our clients, TFS build server was choking for no good reason with the following error “Please contact your administrator. There was an error contacting the server. Technical information (for administrator): System.ServiceModel.ServiceActivationException.” Not very useful error message, isn’t it? TFS logs were a bit more informative and had the following error:
WebHost failed to process a request.
Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/4342953
Exception: System.ServiceModel.ServiceActivationException: The service '/tfs/queue/DefaultCollection/Services/v4.0/MessageQueueService2.svc' cannot be activated due to an exception during compilation. The exception message is: This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. If your service is being hosted in IIS you can fix the problem by setting 'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' to true or specifying 'system.serviceModel/serviceHostingEnvironment/baseAddressPrefixFilters'.
Parameter name: item. ---> System.ArgumentException: This collection already contains an address with scheme http. There can be at most one address per scheme in this collection.

Process Name: w3wp
Now, that’s a much better error message. It actually tells us that the problem is caused by multiple bindings in IIS on TFS website and it tells us how this error can be fixed. I love such errors. Anyway, to fix the problem we need to add the following line to web.config file on TFS server:
Then restart TFS Build Service, and it’s all good again…
Shortly after I published my last blog entry on the complaints that developers have about writing unit test (see Do I Have to Unit Test), I came across this blog entry from Derick Bailey entitled “You Are Not Paid to Write Software”. This approached the issue of excuses for the lack of unit tests from a different angle. And one that I wholeheartedly agree with.
So let me ask those of you who are professional developers a simple question. What do you think your job is?
Is your job to write the code that your boss tells you to write?
Is you job to write the code to implement every feature that your users ask for?
Is your job to find the most efficient and effective way to move the contents of a database and put it onto the screen?
Is it to optimize the code that you’re writing to squeeze every last drop of performance from it?
I’m going to suggest that you should have answered no to every single one of those questions.
If you are a developer, your job is to solve problems. The process is supposed to go as follows: users describe the problem, you develop a solution to the problem, you deliver solution to the problem, user is happy.
Sounds almost too easy, doesn’t it :)
But there is an unspoken contract in this process. Once you have solved a problem, there is no reason why you should have to solve the problem again. You don’t want to have to solve it again. And the user has no reason to have you solve it again. Not to mention that the user doesn’t want to find out that the problem that was previously solved is back again.
So why do you not do everything in your power to keep this from happening? And what is one of the simplest steps you could take?
Write unit tests.
You see? Derrick is correct. You are not paid to write software. You are paid to solve problems. And to make sure that they stay solved. Again, what is one of the easiest ways to make sure this happens?
Write unit tests!
Keep that in mind they next time you question whether you should be writing unit tests. It’s actually not a question that should come up. Writing unit tests should be part of your job. And if it’s not, then ask yourself what you think your job really is?
