Cannot use fluent html lambda expressions in Spark view

I'm attempting to use fluent html and the spark view engine in my asp.net mvc application. I've assinged the proper base class, added the assemblies, and when i do this.TextBox("MyProperty") it works fine. However I get the below exception when i attempt to use this.TextBox(m=>m.MyProperty). Any idea what can be causing this?

Exception:

Dynamic view compilation failed.

If you really assigned the proper base class, then this exception usually means that you have invalid property in your lambda expression. Double-check it. You actually didn't show nor your spark view nor the code. But, as an example, if you have 

public string Name { get; set; }

and use 

this.Hidden(x => x.Name1)

you'll get this error (followed by another exception).
