Answer 1

It looks like the actual error message here is:
Failed to resolve System.Web.AspNetHostingPermissionLevel
This type is in the System.dll assembly (according to MSDN). Unity references the System.dll assembly, so it should be able to find this assembly. However, Unity can target different .NET profiles.
Look for the current profile setting by choosing File > Build Settings from the menu, then select the Player Settings button. You should see something like this in the inspector:
Make sure that you are using the ".NET 2.0" option here, not the ".NET 2.0 Subset" option. The type System.Web.AspNetHostingPermissionLevel does not exist in the .NET 2.0 Subset profile.
It is likely the case that some pre-built assembly in the project was built against the .NET 2.0 profile, so it is trying to use this type.
