Compile error when using MQTTnet.AspNetCore v3.0.3 (and 3.0.7).

See original GitHub issue

I get the following compile error when trying to build a sample project with MQTTnet.AspNetCore v3.0.3 from NuGet. I have tried adding MQTTnet v3.0.3 to the project, but with no effect.

The code compile and executes when v3.0.2 is used, but v3.0.3 does not.
