# -nostdlib (Visual Basic)

Causes the compiler not to automatically reference the standard libraries.

## Syntax

-nostdlib


## Remarks

The -nostdlib option removes the automatic reference to the System.dll assembly and prevents the compiler from reading the Vbc.rsp file. The Vbc.rsp file, which is located in the same directory as the Vbc.exe file, references the commonly used .NET Framework assemblies and imports the System and Microsoft.VisualBasic namespaces.

Note

The Mscorlib.dll and Microsoft.VisualBasic.dll assemblies are always referenced.

Note

The -nostdlib option is not available from within the Visual Studio development environment; it is available only when compiling from the command line.

## Example

The following code compiles T2.vb without referencing the standard libraries. You must set the _MYTYPE conditional-compilation constant to the string "Empty" to remove the My object.

vbc -nostdlib -define:_MYTYPE=\"Empty\" T2.vb
