You will find something similar to the following .method private hidebysig static void Main string args cil managed .entrypoint Code size 15 0xf .maxstack 1 .locals init 0 class Chapter3.DynamicComplex.TestClass t IL_0000 nop IL_0001 newobj instance void Chapter3.DynamicComplex.TestClass .ctor IL_0006 stloc.0 IL_0007 ldloc.0 IL_0008 callvirt instance void Chapter3.DynamicComplex.TestClass Method1 IL_000d nop IL_000e ret end of method Program Main However if we alter our t variable to the following dynamic t new TestClass t.Method1 . then the IL will look very different I have removed some of the IL to save some trees class mscorlib System.Collections.Generic.IEnumerable 1 class Microsoft.CSharp Microsoft.CSharp.RuntimeBinder.CSharpArgumentInfo IL_003a call class System.Core System.Runtime.CompilerServices.CallSite 1 0 class System.Core System.Runtime.CompilerServices.CallSite 1 class mscorlib System.Action 2 class System.Core System.Runtime.CompilerServices.CallSite object Create class System.Core System.Runtime.CompilerServices.CallSiteBinder IL_003f stsfld class System.Core System.Runtime.CompilerServices .CallSite 1 class mscorlib System.Action 2 class System.Core System.Runtime.CompilerServices.CallSite object Chapter3.DynamicComplex.Program Main oSiteContainer0 p__Site1 IL_0056 callvirt instance void class mscorlib System.Action 2 class System.Core System.Runtime.CompilerServices.CallSite object Invoke 0 1 Whoa what is happening here Well the short answer is that calls to dynamic methods are sent to the Dynamic Language Runtime for resolution. It is time to take a look into how the DLR works. 57 CHAPTER 3 LANGUAGE AND DYNAMIC CHANGES Dynamic Language Runtime DLR The Dynamic Language Runtime DLR is behind all the cool dynamic functionality and sits just above the core .NET framework. The DLR s job is basically to .
