Example solution demonstrating Debugger crash (7.25 KB, application/zip)

Description Ben Buttigieg 2017-06-14 15:42:54 UTC
Using Visual Studio for Mac I have been unable to Debug a failing nunit test as the debugger keeps crashing.

When I hit a breakpoint and attempt to inspect an object retrieved from a service locator, the debugger says evaluating then instantly crashes the session.

Works fine in Visual Studio 2017. I am able to evalate and inpect the returned object without issue.

Will attach code to repro issue.

I can reproduce this, but based on crash looks like runtime problem.
Comment 3 Ben Buttigieg 2017-06-15 16:14:09 UTC
Note the crash does not occur in Visual Studio 2017

@Ben, could you verify if your issue is fixed? If not, what do you need to verify it?
