/nostdlib (Do Not Import Standard Library) (C# Compiler Options) 

/nostdlib prevents the import of mscorlib.dll, which defines the entire System namespace.

/nostdlib[<U>+</U> | -]

Use this option if you want to define or create your own System namespace and objects.

If you do not specify /nostdlib, mscorlib.dll will be imported into your program (same as specifying /nostdlib-). Specifying /nostdlib is the same as specifying /nostdlib+.

To set this compiler option in the Visual Studio development environment

  1. Open the Properties page for the project. For details, see How to: Set Project Properties (C#, J#).

  2. Click the Build properties page.

  3. Click the Advanced button.

  4. Modify the Do not reference mscorlib.dll property.

For information on how to set this compiler option programmatically, see NoStdLib.
