What permission set does the AppDomain CreateInstance required?

Question

I have the following code,

appDomain.CreateInstance(
                assemblyName, typeName, false, BindingFlags.NonPublic | BindingFlags.Instance,
                null, new object[] { language, encoding }, CultureInfo.CurrentCulture, null).Unwrap()

I am getting this error,

System.Security.SecurityException: Request failed.

It should inherit it, because otherwise marshaling between two different AppDomains won't work. In that case it will try to serialize\deserialize your type from appDomain to current AppDomain — Sergey Litvinov, Jan 14 '14 at 14:03
You use AppDoman just for creation object? It's a bit strange for me, because the only thing that will happens in AppDomain is creation, and then it will try to serialize it. Are you trying to make Sandbox AppDomain? — Sergey Litvinov, Jan 14 '14 at 14:05
@SergeyLitvinov, Actually I am debugging RazorEngine. See my previous quesion. — Imran Qadir Baksh - Baloch, Jan 14 '14 at 14:11
Try setting permissions specified here http://msdn.microsoft.com/en-us/library/3c7zbfty(v=vs.110).aspx (.NET Framework security section) — garf1eld, Jan 14 '14 at 14:34
