How to resolve errors running Visual Studio on Windows Media Center

I have heard from a few folks who have run into issues trying to install and run Visual Studio on the Windows Media Center 2005 OS.  One of the most common errors reported in this scenario is the following:

The application for project '<project_name>.csproj' is not installed. Make sure the application for the project type (.csproj) is installed.

This error will occur when trying to create or open a C# project in the Visual Studio IDE.  When I looked into this further on one customer's machine, I found that the root cause was similar to an issue I wrote about in this previous blog post.  In this scenario, the underlying problem occured when upgrading a system with Media Center 2004 and the .NET Framework 1.1 installed to Media Center 2005.  This upgrade scenario will cause %windir%\system32\mscoree.dll to be reverted from the .NET Framework 1.1 version to the .NET Framework 1.0 version, which breaks a lot of functionality that depends on the .NET Framework 1.1.

If you run into this error when using the Visual Studio IDE, I suggest trying the workaround described in this blog post to uninstall and reinstall the version of the .NET Framework that is associated with the version of Visual Studio that you are using (.NET Framework 1.0 for Visual Studio .NET 2002, .NET Framework 1.1 for Visual Studio .NET 2003, or .NET Framework 2.0 for Visual Studio 2005).

Please note that although I have described an upgrade scenario that will only happen on the Windows Media Center OS, this error could also happen on a non-Media Center OS as well.  The workaround has proven helpful in resolving this error in non-Media Center OS scenarios as well, so I suggest you try it if you run into it on a non-Media Center OS too.

    I know this is an old post but have you come across any other problems running VS2005 on Windows Media Center Operating System?



  2. Hi Billuk35 – I have not heard of any specific issues running Visual Studio 2005 on Windows XP Media Center Edition.  I’ve been using these products together ever since VS 2005 shipped as well.  Are you having any troubles?  If so, can you please describe them in more detail?

    Hi, thanks for your answer. I’m thinking of replacing my laptop – I use it for VS 2005 development – and there are some good deals in the UK at the moment but the specific machines come with XP WMC rather than XP Pro or XP Home. Before buying one I wanted to check that there are no potential problems but it’s hard to find anyone using VS2005 on XP WMC!



  4. Hi Bill – You shouldn’t encounter any issues with this configuration, and it is officially supported.  If you do happen to hit any problems please let me know and I’ll be happy to try to help unblock you.
