"Open with..." behavior differs from Windows Explo

[j3rky]

We have a Visual Studio 2010 solution file that consists of a mix of C++ and C# projects. When right-clicking the .sln file, selecting "Open with..." and then picking Visual Studio 2010, some of the C# projects do not load. Visual Studio reports that those projects are already open in the solution, which makes no sense.

This problem also occurs when simply double-clicking the .sln file. We were not able to reproduce it with the "Open with..." option in Windows Explorer.

We believe that something might be going wrong with the environment that is passed from TC into VS2010.

We tried TC8.0 and TC8.01rc4.

"Open with..." isn't handled by Total Commander itself. It's all handled by the IShellFolder object.

I have written a test tool in C/C++ which calls the context menu like Total Commander. You can download it here (with full source):

Maybe it helps you to find the problem.

I have the same issue as j3rky has but now with visual studio 2017. What came out of the test? Is there a fix?

Maybe you are running Total Commander with higher user rights (as administrator)? This will cause problems if visual studio was already running with normal user rights when you try to open a file.

Nope, I am running total commander with "normal user rights". I even re-installed total commander. Up to yesterday it always worked. Double clicking on a .sln file opened it in VS 2017. Now, it fails. " A project with that name is already opened in the solution". It's like total commander opens the solutions twice (although I can only see 1 instance running).

"A project with that name is already opened in the solution".

Long lasting problem in Visual Studio:

I don't think that this is TC related.
I'm even getting this error sometimes if I open a new solution via "VS2015-File->Recent Projects and Solutions"
