1) Create an assembly (dll) that references the GwxRuntimeCore assembly.

2) Derive a new class from GwxPickCommand and override virtual members to provide command-specific functionality.

3) Included the assembly name or assembly codebase in the "GwxPickCommands" section of the file Gwx.config.xml. For example:

CopyC#

<GwxPickCommands assemblyName1="SampleCommands1" assemblyName2="SampleCommands2" assemblyCodebase1="SampleCommands3.DLL" assemblyCodebase2="http://www.iconics.com/SampleCommands4.DLL" />

Note: if an assembly codebase is specified as a relative URL, the assembly location will be assumed to be relative to the location of GwxRuntimeCore.dll.

When deriving from this class, add properties to represent the parameters of the command (these properties must be XML-serializable in order to be saved). Override the virtual funtions to provide command-specific behavior.
