Remarks

You apply the LinqToEntitiesDomainServiceDescriptionProviderAttribute attribute to a domain service to specify that the domain service exposes LINQ to Entities mapped types. Typically, you do not have to manually apply this attribute because it is already applied to the LinqToEntitiesDomainService<TContext> class. The LinqToEntitiesDomainService<TContext> class is the base class for domain service classes that you create through the Add New Domain Service Class wizard when the domain service exposes LINQ to Entities types. You need to manually apply this attribute if you want to expose LINQ to Entities types, but you do not want to use a domain service class that derives from the LinqToEntitiesDomainService<TContext> class.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
