How to reference to assembly in mvc at runtime

In my Asp.Net MVC application, i have some view file (.cshtml) which has reference to an external library which it will be loaded at runtime. so after app started, i load the assembly by Assembly.Load and i register the controllers by my own custom ControllerFactory and every thing is ok.

But, in some views which has references to the dynamically loaded assembly, throws the :

Compiler Error Message: CS0234: The type or namespace name 'MyDynamicNamespace' does not exist in the namespace 'MyApp' (are you missing an assembly reference?)

exception that tells the razor compiler cannot resolve the related assembly.

My question is that, is there a way to register the assembly at runtime, to able the razor compiler can access to it and resolve it?

Notice that i can't use BuildManager.AddReferencedAssembly method because my assembly have to be loaded after app start, and the BuildManager does not support it.
