Sample minimal ASP.NET core API to test dynamic reflection with preloaded Testable instances and posted assemblies containing these.

Assemblies can be created with the Testable package (available from nuget.org) and one or more implementations of the TestableBase class. These can then be tested by posting to the API using https://localhost:7286/UploadTestable (assuming default port and running locally) and the dll file within the form-data.
