The !version extension displays the version information for the extension DLL.
This extension command should not be confused with the version (Show Debugger Version) command.
Specifies the extension DLL whose version number is to be displayed.
This extension is available in most extension DLLs.
If the extension DLL version does not match the debugger version, error messages will be displayed.
This extension command will not work on Windows XP and later versions of Windows. To display version information, use the version (Show Debugger Version) command.
The original purpose of this extension was to ensure that the DLL version matched the target version, since a mismatch would result in inaccurate results for many extensions. Newer DLLs are no longer restricted to working with only one version of Windows, so this extension is obsolete.
