Refreshes the schema of the underlying data source.
Assembly: System.Design (in System.Design.dll)
If you implement the IHierarchicalDataSourceDesigner interface to create your own data source and the schema will never change, the CanRefreshSchema property should always return false and the method should raise a NotSupportedException.
Typically, if the is called by the design host as a result of user action, the preferSilent parameter would be false, because the user would expect to be notified of any problems with refreshing the schema. But, if the schema is refreshed implicitly, such as after a call to the Configure method, or if the refreshing process involves a number of steps, preferSilent should be set to true.
