I am using Visual Studio 2010 sp1
When I am opening .NET 4.0 application in VS 2010, I am getting an Output message as
Loading F:\Projects..\Project.csproj ... F:\Projects..\Project.csproj : error : The project file 'F:\Projects..\Project.csproj' cannot be opened. The project type is not supported by this installation.
But I am able to open other projects in the application. They are loaded properly.
Provide me a solution for how to open. Thanks.
