Remarks

The SQL Server LIKE functionality cannot be exposed through translation of existing common language runtime (CLR) and .NET Framework constructs, and is unsupported outside of a LINQ to SQL context. The use of this method outside of LINQ to SQL will always throw an exception of type NotSupportedException.
