“the project type is not supported by this installation” error

Question

I have installed VS 2008 SP1 on W2k3 OS. After I installed ASP.NET MVC beta and tried creating ASP.NET MVC type project I get the following error.

\"the project type

Answer 1

My situation was slightly different: I was trying to open an existing MVC 3 project. Turns out I didn't have MVC 3, installing it from here fixed the problem for me.

Answer 2

This might be obvious, but it fixed it for me. I had installed ASP.NET MVC prior to installing Visual Studio 2008. Once I removed MVC and reinstalled, I no longer had the problem.

Answer 3

I had to rebuild my development VM to solve this one. Clean install FTW.

Answer 4

I came across something while having issues of my own.

In short, try:

• Run the Visual Studio Command Prompt as Admin.

• Execute:

  devenv /setup
  

It then whirs away for a bit (VS2008 will not open), once the prompt returns fire up VS and all (may) be back to normal.

I came across this when my MVC projects got messed up when trying to get the Entity Framework up and running :)

Answer 5

I kept running into this problem. Running devenv /setup and devenv /resetskippkgs did not work for me. Nor did removing project guids. I installed MVC 1.0 and it still didnt work. Then I installed MVC 2.0 and that seemed to do it.

Answer 6

Tried to install ASP.NET MVC 1.0. It works to me.
