NET7 System.Runtime.InteropServices.SEHException: 'External component has thrown an exception.'

[northstarvn]

Steps to reproduce:

1. Create a solution with: C# console, C++ DLL, C# dll (for exports). All attached in zip
2. Test the C++ export OK
3. The C# dll export following guidance here https://github.com/3F/DllExport/issues/130 fails with SEH exception. Even a manual config of the testExport.csproj to x86 didn't help and produced the same problem.
4. Disassembly suggests the export entry doesn't point to function body

• DllExport -version: 1.7.4
• Used Visual Studio / MSBuild / ...: VS Community 2022 (64-bit) Version 17.6.2

Hi @3F

I am also facing the same issue, i have recently upgraded the projects from .Net 4.8 to .net core <TargetFramework>net8.0-windows</TargetFramework>

May i get some help on fixing the issue?

Hello. Thanks for the report!

.NET 8 & .NET 7 (@northstarvn's testDll.zip) are not supported at the moment and it was already discussed in previous issues.

My implantation is planned according to the new priorities described in my last article
