public interface IVsWCFMetadataStorageProvider
The IVsWCFMetadataStorageProvider type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
.gif "Public method") |
AdviseWCFMetadataStorageProviderEvents | Registers the caller for metadata storage provider event notification. |
|
CreateStorage | Creates a new Windows Communication Foundation (WCF) metadata storage. |
|
GetStorageFromMapFile | Returns a Windows Communication Foundation (WCF) metadata storage based on the full path of a .svcmap file. |
|
GetStorages | Enumerates Windows Communication Foundation (WCF) metadata storages in a project. |
|
IsValidNewReferenceName | Returns a value that determines whether a name for a Windows Communication Foundation (WCF) service reference is unique. |
|
MakeValidReferenceName | Returns a unique name and namespace for a Windows Communication Foundation (WCF) service reference. |
|
UnadviseWCFMetadataStorageProviderEvents | Cancels registration for metadata storage provider event notification. |

Remarks
Project systems must implement this interface. Call this interface to create a new storage to save a service reference group, or emulate existing storages in the project.
The project system must determine the correct directory structure to store its metadata.
Examples
The following example uses the IVsWCFMetadataStorageProvider interface to determine whether a project supports WCF service references.
/// Helper method to determine if WCF ServiceReferences are
/// supported by the given hierarchy.
private static bool
ServiceReferencesSupported(IVsWCFReferenceManagerFactory factory,
IVsHierarchy hierarchy)
{
if (hierarchy != null)
{
// Try to see if Reference Manager Factory supports it.
if
(!Convert.ToBoolean(factory.IsReferenceManagerSupported(hierarchy)))
{
return false;
}
/// If factory supports, then ask Hierarchy. They both need to
/// support it.
if ((hierarchy as IVsWCFMetadataStorageProvider) != null)
{
try
{
object objIsServiceReferenceSupported;
ErrorHandler.ThrowOnFailure(hierarchy.GetProperty
(Microsoft.VisualStudio.VSConstants.VSITEMID_ROOT,
(int)__VSHPROPID3.VSHPROPID_ServiceReferenceSupported,
out objIsServiceReferenceSupported));
if (objIsServiceReferenceSupported != null &&
objIsServiceReferenceSupported is bool)
{
return (bool)objIsServiceReferenceSupported;
}
}
catch (NotImplementedException)
{
// If the property isn't implemented in the current
// project system, then we know that
// service references aren't supported.
}
}
}
return false;
}
