I am learning C# so I apologise if I cannot be extremely precise in describing the error.

I was following Pluralsight course and at the section of Unit Testing I realised that the Unit Test does not run on my projects.

It casts the following error:

[19/11/2018 22:13:26 Error] Failed to launch testhost with error: System.AggregateException: One or more errors occurred. ---> Microsoft.Build.Exceptions.InvalidProjectFileException: The project file could not be loaded.

[19/11/2018 22:13:26 Informational] ========== Run test finished: 0 run (0:00:00.0535907) ==========

I have found different resources online
https://developercommunity.visualstudio.com/content/problem/212059/unable-to-debug-unit-test-visual-studio-enterprise.html

And different solutions:
first to disable a VPN (which I don't have) and then to Run “set-mppreference -EnableNetworkProtection 0” in an elevated PowerShell prompt, and restart VS.

None of this method has ultimately work and I am unable to run any test.
