Type Methods (LINQ to Entities)

[This topic is pre-release documentation and is subject to change in future releases. Blank topics are included as placeholders.]

The LINQ standard query operators that deal with CLR type conversion and testing are supported in the Entity Framework. Only CLR types that map to the Entity Data Model (EDM) primitive types are supported in LINQ to Entities. For a list of the EDM primitive types, see Entity Data Model Types. The following table lists the supported and unsupported type methods.
