Impact of changes to the CAS policies in .NET 4.0?

Question

As stated here, the way evidence is loaded will change in .NET 4.0. How will this impact systems like SharePoint where you can specify exactly which permission will be granted for a dll in the wsp-package? Isn’t SharePoint using AppDomain.ExecuteAssembly(Name,Evidence) internally to make this possible, or am I missing something?

Answer 1

.NET 4.0 won't be used for SharePoint until the release after SharePoint 2010. We will still be on .NET 3.5 until then. So perhaps revisit this issue at a later date.
