How to create an object in a foreign assembly

gistfile1.cs

using System.Reflection;
using System.CodeDom.Compiler;
using Microsoft.CSharp;

dynamic foreignMember = CSharpCodeProvider
    .CreateProvider("CSharp")
    .CompileAssemblyFromSource(
        new CompilerParameters
	{
	    GenerateInMemory = true,
	    GenerateExecutable = false,
	    IncludeDebugInformation = false
	},
	new[]
	{
	    "public static class Test { public static object GetModel() { return new { Name = new { Last = \"Nancy\" }}; } }"
	})
    .CompiledAssembly
    .GetType("Test")
    .GetMethod("GetModel")
    .Invoke(null, null);

Note this is useful for testing cross-assembly code
