Assembly: Microsoft.VisualStudio.Shell (in

public static readonly Guid UICONTEXT_EmptySolution
public static final Guid UICONTEXT_EmptySolution
public static final var UICONTEXT_EmptySolution : Guid

A successful call to GetCmdUIContextCookie with UICONTEXT_EmptySolution as the first parameter returns the GUID value of the command UI context associated with this specific UI state.

The new UI context (which in this case is UICONTEXT_EmptySolution) may be retrieved with a call to OnCmdUIContextChanged
