SqlClient for Entity Framework Functions
The .NET Framework Data Provider for SQL Server (SqlClient) for the Entity Framework provides a set of functions to perform mathematical and aggregation calculations, as well as functions to perform System.DateTime and string operations. These functions are in the SQLServer namespace.
For a list of functions that should work with any provider, see Canonical Functions.
