Microsoft.OpenApi 2.0.0 is not supported for use with Microsoft.AspNetCore.OpenApi 9.0.x due to breaking changes in the former that cannot be addressed in the latter.

It will be supported in .NET 10.

I remove it from .csproj but the error persists.

Microsoft.OpenApi 2.0.0 is still present in the code: https://github.com/khteh/AspNetCoreWebApi/blob/038a9295495f1d121e25356c15856e51f6485993/src/Web.Api/Web.Api.csproj#L40
