Defines GUIDs and IDs that are used by other VSCT elements. For unmanaged code, this information typically comes from the header files that are specified by Extern Element. Managed code uses the child elements of the Symbols element to define this information.

If you create a .vsct file from an existing .cto file, the symbols will be generated as children of the Symbols element. For more information, see How to: Create a .Vsct File from an Existing .Cto File.

The Symbols element should not be confused with the Define Element, which defines name-value pairs for use by the preprocessor.

Syntax

<Symbols>
  <GuidSymbol>... </GuidSymbol>
  <GuidSymbol>... </GuidSymbol>
