-nostdlib prevents the import of mscorlib.dll, which defines the entire System namespace.
Syntax
-nostdlib[+ | -]
Remarks
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 project's Properties page.
2.Click the Build property page.
3.Add the option in the "Extra Command Line options" property
