DbConfiguration.SetDefaultSpatialServices(DbSpatialServices) Method

Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Call this method from the constructor of a class derived from DbConfiguration to set the global instance of DbSpatialServices which will be used whenever a spatial provider is required and a provider-specific spatial provider cannot be found. Normally, a provider-specific spatial provider is obtained from the a DbProviderServices implementation which is in turn returned by resolving a service for DbSpatialServices passing the provider invariant name as a key. However, this cannot work for stand-alone instances of DbGeometry and DbGeography since it is impossible to know the spatial provider to use. Therefore, when creating stand-alone instances of DbGeometry and DbGeography the global spatial provider is always used.

The spatial provider.
Remarks
This method is provided as a convenient and discoverable way to add configuration to the Entity Framework. Internally it works in the same way as using AddDependencyResolver to add an appropriate resolver for DbSpatialServices. This means that, if desired, the same functionality can be achieved using a custom resolver or a resolver backed by an Inversion-of-Control container.
