I want to create a C# .Net dll as Add-In for Enterprise Architect in Visual Studio.This dll has to be registered for com-interop to be used by Enterprise Achitect.
Within this dll I also want to do a database migration with code first and nuget package microsoft.entityframework.core.This database migration works fine with the paket manager console in visual studio if the com-interop checkbox in project properties build is un-checked.If it's checked my dll can't compile.The error message is:
The assembly "... .dll" can not be registered. The method "DisposeAsync" in type "Microsoft.EntityFrameworkCore.DbContext" of assembly "Microsoft.EntityFrameworkCore, Version 3.1.8..."has no implementation.
In my original code I have no functions with any kind of Dispose or similar. It's a simple project with a few lines of code.I tried to manage it in nuget package manager with older versions of Microsoft.EntityFrameworkCore, but it didn't help.Also I had overwritten the DisposeAsync function within my code, but this didn't also help.
The relevant code is within the context class the line with DbContext:
using Microsoft.EntityFrameworkCore;namespace ...{ public class .. : DbContext {In Google I couldn't find anything so please help me.
