DbXmlEnabledProviderManifest Class

Represents a base class that implements the DbProviderManifest based on an XML definition. You can use the DbXmlEnabledProviderManifest class to obtain provider-specific information at runtime.

Namespace:  System.Data.Common
Assembly:  System.Data.Entity (in System.Data.Entity.dll)

public abstract class DbXmlEnabledProviderManifest : DbProviderManifest

The DbXmlEnabledProviderManifest class is especially appropriate for the providers whose type mapping to EDM is symmetrical. In symmetrical type mapping scenarios, each storage type maps to a single Entity Data Model (EDM) type regardless of the mapping direction. In other words, the EDM-to-provider type mapping is the same as the provider-to-EDM type mapping.

In symmetric mapping scenarios, you can either derive your custom provider class from the DbXmlEnabledProviderManifest class or the DbProviderManifest class. We recommend that you derive your custom provider class from the DbXmlEnabledProviderManifest class for symmetric mapping scenarios because the DbXmlEnabledProviderManifest class will allow you to specify the manifests declaratively.
