One or more types required to compile a dynamic expression cannot be found. Are you missing references to Microsoft.CSharp.dll and System.Core.dll (via: C# 4.0 and .Net 3.5 – Stack Overflow)

If you get any of the two errors below while compiling your .NET app, then one of these things happened:

  1. You moved .NET 4 or higher code that makes use of dynamic into an assembly that does not reference the Microsoft.CSharp.dll and System.Core.dll assemblies.
  2. You tried changing the .NET version of a project back to .NET 3.5 or lower.

Note that it is not so much declaring a variable as dynamic, but using that variable.

Predefined type ‘Microsoft.CSharp.RuntimeBinder.Binder’ is not defined or imported
