Null Reference Error After PC Crash

[TvdVen]

Today I attempted to add a unit testing project to my VisualGDB solution. Unfortunately, my PC crashed during this process.
Since then, when attempting to do the same, I receive a null reference exception in Visual Studio.

I have tried uninstalling and re-installing VisualGDB, as creating non-VisualGDB projects in Visual Studio still seems to function properly.

The following is the full exception information:

VisualGDB version: 5.3.18.1973

Can anyone offer advice? I’m at a loss for what to try next.

Hi,

This could indicate a corrupt test framework cache. Please try deleting the %LOCALAPPDATA%\VisualGDB\TestFrameworks folder.

If this doesn’t help, please open the View->Other Windows->VisualGDB Diagnostics Console and try reproducing the problem again, then post the diagnostic output. This should help us pinpoint this.

This did resolve my issue, thank you 🙂
