After I updated Typemock Isolat0r to version 5.3.1, F# stopped working with Visual Studio. Every time I try to build, I get an error stating "fsc.exe has stopped working". Debugging showed me the following:
Description:

I only realized it was Isolator after reinstalling Visual Studio and all of my tools one at a time until Isolator finally proved to be the culprit. I couldn't figure out what was happening to cause the issue other than the presence of Isolator being installed.
As a work-around, I can run MSBuild from the command line.
