Common Intermediate Language (CIL, pronounced either sil or kil), formerly called Microsoft Intermediate Language (MSIL), is the lowest-level human-readable programming language defined by the Common Language Infrastructure (CLI) specification and is used by the .NET Framework and Mono. Languages which target a CLI-compatible runtime environment compile to CIL, which is assembled into an object code that has a bytecode-style format. CIL is an object-oriented assembly language, and is entirely stack-based. Read more on Wikipedia...

Example from the web:

.assembly Hello {}
.assembly extern mscorlib {}
.method static void Main()
{
    .entrypoint
    .maxstack 1
    ldstr "Hello, world!"
    call void [mscorlib]System.Console::WriteLine(string)
    ret
}

Example from Riju:

.assembly main {}
.class Main
{
  .method static void Main() cil managed
  {
    .entrypoint
    ldstr "Hello, world!"
    call void [mscorlib]System.Console::WriteLine(string)
    ret
  }
}

Example from hello-world:

// ilasm cil.il
.assembly HelloWorld {}
.method public static void Main() cil managed
{
     .entrypoint
     .maxstack 1
     ldstr "Hello World"
     call void [mscorlib]System.Console::WriteLine(string)
     ret
}

Example from Wikipedia:

.method assembly static void modopt([mscorlib]System.Runtime.CompilerServices.CallConvCdecl)
        test_pointer_operations(int32 param) cil managed
{
  .vtentry 1 : 1
  // Code size       44 (0x2c)
  .maxstack  2
  .locals ([0] int32* ptr,
           [1] valuetype A* V_1,
           [2] valuetype A* a,
           [3] int32 k)
// k = 0;
