GetUserResponse return a null 204 error

[TeoDanilo]

EDIT / UPDATE

The problem is not with the .net version, is with the NetDevPack.Identity version. This issue occurs with the 1.2.0 version only. Using the 1.1.1 work perfectly even with .net5

---------------------------

Describe the bug
Trying to change the default GetFullJwt to GetUserResponse at Login action in AccountController in a .net5 project return an error 204 when try to Login or create a new Account (note that, even though return an error, the user is created at data base). Using with .net core 3.1 work just fine

To Reproduce
Just try to use with an .net5 project

Expected behavior
The response should be 200 with the user's token and infos.

The method produces an error? Can I you show the details?

This project will be revisited for the new .NET 5 very soon.
