If tests eventually call down to native code, it's extremely useful to be enable the mixed debugger. This is done by choosing "Enable native code debugging" in the project settings.
However, when debugging unit tests CodeRush appears to be ignoring this settings and always invokes the managed debugger:
'DevExpress.CodeRush.TestRunner.Executor45x64.exe' (Managed (v4.0.30319)) : Loaded 'C:\Windows\Microsoft.Net\assembly\GAC_64\mscorlib\v4.0_4.0.0.0__b77a5c561934e089\mscorlib.dll', Symbols loaded.
Please support the ability to use the mixed debugger as we currently use an alternative product to do this.
David,
Thank you for the report. We will work on improving native debugging support in future updates of the product.
