Description Rolf Bjarne Kvinge [MSFT] 2017-10-06 11:37:48 UTC
Repro:

* Create a new command-line project.
* Change the project settings to not use an external terminal (in Run/Configurations/Default uncheck "Run on external console")
* Add to Main:

    Console.WriteLine (new string ('x', 50_000_000));

* Put a breakpoint on the line after the Console.WriteLine (end of the Main method)
* Run.

The problem is obvious here, but not necessarily if you print something that suddenly ends up an enormous line (because VSfM will hang and you have no way of diagnosing why).
