C# Unmanaged Func works with NETStandard but fail in NETCore

[zikitrake]

Has anyone worked with calls to .NET lib functions from PB? (using UnmanagedExports.Repack and UnmanagedExports.Repack.Upgrade)

When I create a library in NETSTANDARD 2.1 everything works OK.
But if the library is in .NET CORE 3.1 (or lower), my PB program closes with the message "The debugged executable quit unexpectedly"

Here I put simple capture of 2 examples of libraries (NetStandard2 and NetCore3)

NET CORE 3.1 image


And the PB Results:


Thank you and happy holidays

PS: I tried 3F/DllExport v1.7.3 but I get always an infinite loop when execute it
