Remarks

MVC requires that a data model be configured to use a metadata provider. Set Current to null reference (Nothing in Visual Basic) to set the current metadata provider to the EmptyModelMetadataProvider provider.

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.
