Upgrading MVC project in VS 2010 b2: The project type is not supported by this installation

Question

Consider the scenario of upgrading an ASP.NET MVC project.

This question is around up-converting a .sln with a .csproj that is of type ASP.NET MVC 1.0.

The conversion log shows this The Visual Studio conversion wizard log gives this exception:

The project file 'C:\MvcForums\MvcForums.csproj' cannot be opened. The project type is not supported by this installation.

After the conversion, the .sln contains this entry for the MVC app. The zerod-guid is obviously the root of the problem:

Project("{00000000-0000-0000-0000-000000000000}") = "MvcForums", "MvcForums\MvcForums.csproj", "{5CDD5F8B-9192-4A63-B4B0-55244C835352}"

Question: How can we convert an MVC app using Visual Studio 2010 Beta 2? Do you have to install MVC 1.0?

Environment:

• Win 7
• No ASP.NET 1.0 installed
• Visual Studio 2010 Beta 2 only
• Stephen Walther's Forums sample app.

Answer 1

Here is a a tool that Phil Haack linked to upgrade mvc1 apps to mvc2 and be usable in 2010. I would take a look at Phils blog, he links to the lead dev of mvc who has some info on the subject.
