Parameters

The following table describes the parameters of the Vbc task.

Parameter Description

If true, suppresses display of compiler banner information. This parameter corresponds to the /nologo switch of the vbc.exe compiler.
NoStandardLib Optional Boolean parameter.

Causes the compiler not to reference the standard libraries. This parameter corresponds to the /nostdlib switch of the vbc.exe compiler.
NoVBRuntimeReference Optional Boolean parameter.

Internal use only. If true, prevents the automatic reference to Microsoft.VisualBasic.dll..

If true, the task suppresses all warnings. For more information, see /nowarn.
Optimize Optional Boolean parameter.

If true, enables compiler optimizations. This parameter corresponds to the /optimize switch of the vbc.exe compiler.
OptionCompare Optional String parameter.

Specifies how string comparisons are made. This parameter can have the following values:

- binary
