I have heard of people wanting and needing to add projects created in Expression Blend to Team Foundation Server. Here is the recipe: 1) Create your project in Expression Blend … click OK 2) Select the option to open your recently created project in Visual Studio. Once that option is selected, your solution will open up in Visual Studio, close Expression Blend at this point. Now, I want to add this project to Source Control … Next, I connect to my TFS environment, and pick the location to save my project Once the project is added, I will get a status window of pending changes for my project, all that we are left to do is to check in those changes. Since we have checked in our project, we can now close Visual Studio, and we will proceed to open Expression Blend again. And select our project we will! We notice some differences from before, just by opening it What differences you say?!? Notice the lock to the right of the item name … And we also get this when we right click … And there we have it, it is a combination of tools to achieve this, but it is well worth it.
