In my control panel i am seting "ASP.NET 2.0 Full Trust". What i need to ask for server administrator to change?

Answer 1

You should be able to bin deploy and run the MVC framework in medium trust. There is a possibility that there is some other permission that the hosting company has taken away but it should work. Are you testing with the default MVC project? If you are using other components (Structure Map, for example), that may be causing the error.

Check out Bin Deploying ASP.NET MVC from Phil Haack about deploying and the required trust level.

Answer 2

Medium trust does not allow certain Reflection operations. I guess some part of your code does or calls other part(s) of code.

Answer 3

Web deploy copies some System.Web dlls to bin folder, for example System.web.MVC but not all. It is kind of lot of debugging to determine which ones are missing, like the previous comment said about reflection methods.
