'execvp(3) failed.: No such file or directory' when project created in vscode is opened in vs

## Steps to Reproduce ##
This problem consistently happens after the following sequence of events.

1. Create a new dotnet application from command line
2. Edit and debug application in "Visual Studio Code" for Mac.
3. Sometime in the future, opening the same application in "Visual Studio" for mac.
4. Open the project in "Visual Studio Code" for Mac, only to find that debugging does not work anymore.

"Visual Studio" is doing something to the application that breaks debugging in "Visual Studio Code".

## Expected Behavior ##
Debugging should work in Visual Studio Code even after opening the project in Visual Studio.

## Actual Behavior ##
Debugging doesn't work when pressing f5.
