We also considered adding another drop down, similar to Debug and Platform drops downs to let the user choose the "active" TFM (like the editor drop down but for all...

The fact that it cannot be opened when you double-click the error is fallout of above - VS thinks that we own the file, but when the Error List asks...

There will not be a change in VS 2017. You can work around this by including a `` that includes them.

Yeah, this is known - but I can't find the bug. I'll use this to represent it. The solution shouldn't be seeing 9A19103F-16F7-4668-BE54-9A1E7A4F7556, it should only be seeing the legacy...

Folks, we understand this is an issue and a bug. Can you help me understand why leaving the GUID as 9A19103F-16F7-4668-BE54-9A1E7A4F7556 for now results in editors thrashing with each other?...

Just a general thing; we have lots of bugs - those with workarounds and don't affect inner loop (ie something a dev does hundreds of times a day), tend to...

Sorry for the late reply. The following GUIDs should be persisted: Language|GUID ---|--- C#|FAE04EC0-301F-11d3-BF4B-00C04F79EFBC Visual Basic|F184B08F-C81C-45F6-A57F-5ABD9991F28F F#|F2A71F9B-5D33-465A-A702-920D77279786 We have a bug that we are switching these GUIDs from above to...

Microsofties, I suspect this will fix this: https://devdiv.visualstudio.com/DevDiv/_git/CPS/pullrequest/122409?_a=overview.

Our rules for opening projects are specified here: https://github.com/dotnet/project-system/blob/master/docs/opening-with-new-project-system.md. If any non-SDK projects match the patterns called out in that doc then they will be opened in new project system.

I've been testing my change above, it does indeed prevent the solution from changing the project type for C# projects from FAE04EC0-301F-11d3-BF4B-00C04F79EFBC -> 9A19103F-16F7-4668-BE54-9A1E7A4F7556. However, it also causes the reverse,...
