If you get this error when opening a solution in Visual Studio, just go to the project file (YourProject.csproj) which fails to open and change the line
<ProjectTypeGuids>{Some_GUID}</ProjectTypeGuids>
to
<ProjectTypeGuids>{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
