Methods

EscapeLikeArgument(String)	Provider writers should override this method to return the argument with the wildcards and the escape character escaped. This method is only used if SupportsEscapingLikeArgument returns true.
GetDbInformation(String)	When overridden in a derived class, this method returns provider-specific information.
GetEdmType(TypeUsage)	When overridden in a derived class, this method maps the specified storage type and a set of facets for that type to an EDM type.
GetFacetDescriptions(EdmType)	Returns the FacetDescription objects for a particular type.
GetInformation(String)	Gets the provider-specific information.
GetStoreFunctions()	When overridden in a derived class, returns a collection of EDM functions supported by the provider manifest.
GetStoreType(TypeUsage)	When overridden in a derived class, this method maps the specified EDM type and a set of facets for that type to a storage type.
GetStoreTypes()	When overridden in a derived class, returns the set of primitive types supported by the data source.
SupportsEscapingLikeArgument(Char)	Indicates if the provider supports escaping strings to be used as patterns in a Like expression.
SupportsInExpression()	Returns a boolean that specifies whether the provider can handle expression trees containing instances of DbInExpression. The default implementation returns `false` for backwards compatibility. Derived classes can override this method.
SupportsIntersectAndUnionAllFlattening()	Returns a boolean that specifies whether the provider can process expression trees not having DbProjectExpression nodes directly under both Left and Right sides of DbUnionAllExpression and DbIntersectExpression
SupportsParameterOptimizationInSchemaQueries()	Indicates if the provider supports the parameter optimization described in EntityFramework6 GitHub issue #195. The default is `false`. Providers should change this to true only after testing that schema queries (as used in the Database First flow) work correctly with this flag.
