Open an exising MVC 3 project in visual studio 11 developer preview

I've trying to open and convert an existing vs 2010 mvc 3 project in the new dev 11 preview and am running in to a difficult issue. The solution file will convert successfully, however the one mvc 3 web project in the solution shows in the solution explorer as unloaded post conversion. When i attempt to reload the project from solution explorer, i get prompted to convert the project and receive the following err开发者_高级运维or in the upgradelog.xml

The project file'myproject.csproj' cannot be opened. There is a missing project subtype. Subtype: '{E53F8FEA-EAE0-44A6-8774-FFD645390401}' is unsupported by this installation.

From what i could track down, this has to do with MVC, but that doesn't really help me work around the issue. Any suggestions or workarounds would be appreciated.

Update: Actually, MVC 3 for Visual Studio 11 Dev Preview has just been published: http://www.microsoft.com/download/en/details.aspx?id=1491

We have not yet shipped MVC 3 support in Visual Studio 11. You can work around this by editing your csproj file and removing the project type GUID {E53F8FEA-EAE0-44A6-8774-FFD645390401}. This will cause your project to load like a normal WAP. You will be able to edit your code, however MVC-specific actions (Add Controller, etc) will not be available.

You may want to try the steps from the Upgrading an ASP.NET MVC 3 Project to ASP.NET MVC 4 section of the release notes, even if the document describes the VS2010 version.

I managed to convert a VS2010/MVC3 project, but VS11 shows a warning every time I open the solution, stating that the project requires ASP.NET Web pages with Razor syntx 1.0. OTOH, the project seems to run without any problems (VS11 setup also installed ASP.NET Web pages 2).
