Repair Warning in code.
## 💬 Manage Warnings Repair

Three code analyzers are being used, plus sonar on the server. But he's getting little he caseed. The code generates 2307 Warnings. That should be fixed.

Starting with c# 8, the way null values are treated has changed and would need to be modified.

How is this managed?

I usually fix these problems little by little, when I modify a class, I solve the Warnings that it has.
