Answer 1

ewalshe - same thing worked for me. I know this is an old post, just wanted to put this out there for anybody else. I had an existing solution in source control (Vault), and wanted to set up my home computer for development. I installed Visual Studio 2008 at home without the following options:

C++
Visual Basic
Visual Web Developer

When I pulled down the solution from source control, all projects loaded EXCEPT my web project - VS simply did not recognize it. A fresh installation using the default options and a restart fixed my problem. I do not have the time nor the desire to really figure out which of the above is necessary for Web Application projects to work... maybe somebody will chime in.

I was getting the same error and found this question in a Google search for the answer. Most answers unearthed in the search suggested that old project types were being moved onto a machine with a different version of Visual Studio installed. None of which applied to me.

I've got VS2008 installed on a machine (running 64bit Vista) at work and recently installed the ASP.NET MVC beta, without any problems.

I wanted to replicate my work environment on my Mac, so I installed VS2008 with the ASP.NET MVC beta into a WinXp installation running within a Parallels VM. When I went to create a project with the ASP.NET MVC Web Application template I got the "the project type is not supported by this installation" error.

I finally got things working by yet another reinstall of VS2008 (a clean install, not a repair). This time I choose the default installation options, rather than customising things as I usually do. I normally deselect VB, the mobile device, office and other non C# development stuff - I don't have much free space on my Mac.

After the clean install of VS2008 I did a windows update, installed VS2008 SP1 and finally installed the ASP.NET MVC beta.

It seems that when I customised the VS2008 install, I deselected something essential for the correct operation of the MVC beta. I don't have clue what that something is, I'm just happy that after three days I can play the the MVC stuff at home.

Its been a month since you posted the question. Have you made any progress since?

I had MVC 2 installed on my machine and I was still getting this error message. I installed MVC 1, no GO. i installed web Developer No GO. I finally uninstalled MVC1 and MVC2 and then reinstalled MVC2: http://www.microsoft.com/Downloads/en/details.aspx?familyid=C9BA1FE1-3BA8-439A-9E21-DEF90A8615A9&displaylang=en

The re installation of MVC 2 solved the problem for me. Hope this helps someone else.

Thanks

Tried @ryan and @Rob Cooper answers with no joy. Running this in a vhd on Win7.

Zoned in on Mvc and that's where problem lies. Not 100% but think issue is that I was trying to open a project that didn't have latest Mvc release, which new build had.

Temporary solution is to rollback to previous version of Mvc. Then when that's happy, upgrade project to latest Mvc and then machine.

I had the same problem with MVC v1. Turns out that I hadn't installed the "Visual Web Developer" feature.

This SO user had the same issue.

Vivek Ayer's solution also worked for MbUnit projects. Additionally, simply deleting the first GUID (rather than replacing it with "{349c5851-65df-11da-9384-00065b846f21}") worked.
