This is probably the most wonderful this I have explored in .net. What happens here is a user can actually make the EXE file on the fly. System.Runtime.Emit Namespace provides necessay class to do this.
After compiling this file and running it on the Console a new file is generated in your folder called TestAsm.exe. This Exe file print@#s a message "Hello World" on the Console.

Source Code:

RuntimeEmit.cs   using System; using System.Runtime; using System.Runtime.Emit; Class RuntimeEmit { public static void Main(String [] args) {          AppDomain ad = AppDomain.CurrentDomain;          AssemblyName am = new AssemblyName();          am.Name = "TestAsm";         AssemblyBuilder ab = ad.DefineDynamicAssembly(am,AssemblyBuilderAclearcase/" target="_blank" >ccess.Save);         ModuleBuilder mb = ab.DefineDynamicModule("testmod","TestAsm.exe");         TypeBuilder tb = mb.DefineType("mytype",TypeAttributes.Public);           MethodBuilder metb = tb.DefineMethod("hi",MethodAttributes.Public | MethodAttributes.Static,null,null);         mb.SetEntryPoint(metb);         ILGenerator il = metb.GetILGenerator();         il.EmitWriteLine("Hello World");         il.Emit(OpCodes.Ret);           tb.CreateType();         ab.Save("TestAsm.exe"); } }

Save this file as RuntimeEmit.cs  and Compile C:/>csc RuntimeEmit.cs and run this file C:\>RuntimeEmit  
to run the Exe file generated  C:\>TestAsm
