CAS policy exceptions during CLT running

Problem: you see a lot of exceptions like:

--- EXCEPTION #1/4 [NotSupportedException]
Message = "An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by def ault, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See for more information."
ExceptionPath = Root.InnerException.InnerException.InnerException
ClassName = System.NotSupportedException
HResult = COR_E_NOTSUPPORTED=80131515
