So you have a DLL that was compiled in DotNET?  Did you confirm that the DLL actually exports the desired function?  Is the DLL using something like UnmanagedExports to export a managed .NET function in a way that unmanaged languages like Pascal can call it?

Sorry my internet lucks, was blocked..
Other test for lazarus + dot C#net..
You try these code -lines bellow.

Code: [Select]


Procedure _CorDllMain ; external 'mscoree.dll';
Var msg:string;
Begin
   msg:='Here code/source is Lazarus.units';
   Try  _CorDllMain
Exceptton
    writeln('Error10=Lazarus cannot  load mscoree.dll');
    wrtieln('Error11=Even ; mydll was compiled with {x86targeting} and {not dot.net}')
End;

End.

Code: [Select]

Procedure _CorDllMain ; external 'mscoree.dll';


That is not the correct signature for _CorDllMain, see:
https://learn.microsoft.com/en-us/dotnet/framework/unmanaged-api/hosting/cordllmain-function

It should be:

Code: [Select]

uses
  Windows;

function _CorDllMain(hInst: HINSTANCE; dwReason: DWORD; lpReserved: Pointer): BOOL; stdcall; external 'mscoree.dll';
