[wix-devs] WixToolset.Dnc.HostGenerator errors

Sun Jul 17 19:30:07 PDT 2022

Your workaround worked. Tests are now failing:

---------------------------
Example.TestEngine.exe - Ordinal Not Found
---------------------------
The ordinal 345 could not be located in the dynamic link library X:\tmp\4vr10i1v.li3\ba\dncpreq.dll. 
---------------------------
OK   
---------------------------

And 

Expected: 0: Loading .NET Core FDD bootstrapper application.
Actual:   0: error from hostfxr: You must install or update .NET to run this application.

I have the x86 .NET 6.0.7 runtime installed. Is a different version required?
