Hi scuty,
We have no reason to believe that .NET 4.5 is the cause of this issue, but it's difficult to be sure without knowing the true cause.
By the way, the ClearScript ReadMe contains our recommended procedure for integrating ClearScript into ASP.NET projects, and the discussion thread linked above includes our suggestions for users of the ClearScript.V8 NuGet package.
Good luck!
