last week i upgraded my blogs codebase from ASP .NET Core 2.1 to 3.1. I think anything goes broken.
The build itself works as expected without any errors. Then Visual Studio opens the configured port on localhost. And then i just see a blank page without anything.
If you are also develop with ASP .NET Core, maybe you can have a look about my repository: https://github.com/saigkill/saschamannsde/ ?
I already checked that locations, where i expected an error, but nothing found. :-( I think i have forgotten anything in that codebase...
