That's true (and minimal APIs help a lot) but ASP.NET still has a real problem with too much magic.

For example, the secret incantations required to output a mere string as raw json mimetype or log incoming deserialization errors* are unintuitive and very labourious - see InvalidModelStateResponseFactory. Or that I had to create a custom output formatter to output raw json. Why? Sometimes I just want ASP.NET to get out of my way and it's not trivial to tell it to let go.

* For example, url?parameter=1 for a boolean parameter, which would have worked with .NET Framework but won't for .NET Core/.NET.
