UnityVS visual studio can not open

Question

I use UnityVS generate visual studio project, but project file *.CSharp.csproj could not open.

I find the problem is that ProjectTypeGuids use a unkown type : E097FAD1-6243-4DAD-9C02-E9B9EFC3FFC1 , and google also could not tell me what's that.

anyone has the same problem?

The project file is :

Answer 1

This typically happens in three different scenarios:

• The user is using a trial version of Visual Studio. Currently UnityVS requires a full Visual studio.
• The installation failed to recreate the Visual Studio extension cache. We saw this happen if there was a stray devenv.exe process. Make sure no devenv.exe process is running, and re-install UnityVS.
• The user has an old cracked version of UnityVS installed in the GAC which conflicts with the current UnityVS.

There's also the case where you haven't installed the .NET 3.5 framework which is required by Unity (Unity's class library is a subprofile of .NET 3.5), but the error message is usually explicit about this.

Answer 2

I've fixed this issue by removing and installing UnityVS again. The "Repair" function of UnityVS installer has not changed anything, so I needed to uninstall it completely first.
