Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type ITaggable. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Remarks

Specifying overlapping lists of tags in tagsSet and tagsNotSet always returns false.

Specifying empty lists of tags for both tagsSet and tagsNotSet always returns true.

See Support for Tags for an overview of using this method and the use of the ITaggable interface.

This method may also be used in where-clause expressions for evaluation on the server. See Querying Tags for an overview of querying for specific tags within a LINQ where-clause.
