BeginResolve(IEnumerable<ContractDescription>, EndpointAddress, AsyncCallback, Object)

Begins an asynchronous call that resolves a metadata address into the ServiceEndpoint objects for the specified contracts, using the specified address and asynchronous state and delegate.

public:
 static IAsyncResult ^ BeginResolve(System::Collections::Generic::IEnumerable<System::ServiceModel::Description::ContractDescription ^> ^ contracts, System::ServiceModel::EndpointAddress ^ address, AsyncCallback ^ callback, System::Object ^ asyncState);
public static IAsyncResult BeginResolve (System.Collections.Generic.IEnumerable<System.ServiceModel.Description.ContractDescription> contracts, System.ServiceModel.EndpointAddress address, AsyncCallback callback, object asyncState);
static member BeginResolve : seq<System.ServiceModel.Description.ContractDescription> * System.ServiceModel.EndpointAddress * AsyncCallback * obj -> IAsyncResult
Public Shared Function BeginResolve (contracts As IEnumerable(Of ContractDescription), address As EndpointAddress, callback As AsyncCallback, asyncState As Object) As IAsyncResult

Parameters

contracts
IEnumerable<ContractDescription>

The contracts for which to download and resolve metadata.

address
EndpointAddress

The metadata address.

callback
AsyncCallback

The asynchronous callback delegate invoked when the call is complete.

asyncState
Object

The state associated with the asynchronous call.

Returns

IAsyncResult

The IAsyncResult that references the asynchronous resolve operation.

Exceptions

ArgumentNullException

The address, contract, or callback is null.

ArgumentException

contracts is empty, at least one member of contracts is null, or contracts contains more than one contract with the same name and namespace.

Remarks

The default settings on the System.ServiceModel.Description.MetadataExchangeClient are used to retrieve the metadata and the default System.ServiceModel.Description.MetadataExchangeClientMode is MetadataExchangeClientMode.MetadataExchange.

To download metadata but not resolve the information into ServiceEndpoint objects, use the System.ServiceModel.Description.MetadataExchangeClient directly.

Note

An empty collection is returned if no endpoints were imported or if no endpoints matched the contract. If an empty collection is returned, a warning trace is written.

Applies to

BeginResolve(Type, EndpointAddress, AsyncCallback, Object)

Begins an asynchronous call that resolves a metadata address into the ServiceEndpoint objects for the specified contract using the specified address and asynchronous state and delegate.

public:
 static IAsyncResult ^ BeginResolve(Type ^ contract, System::ServiceModel::EndpointAddress ^ address, AsyncCallback ^ callback, System::Object ^ asyncState);
public static IAsyncResult BeginResolve (Type contract, System.ServiceModel.EndpointAddress address, AsyncCallback callback, object asyncState);
static member BeginResolve : Type * System.ServiceModel.EndpointAddress * AsyncCallback * obj -> IAsyncResult
Public Shared Function BeginResolve (contract As Type, address As EndpointAddress, callback As AsyncCallback, asyncState As Object) As IAsyncResult

Parameters

contract
Type

The contract for which to download and resolve metadata.

address
EndpointAddress

The metadata address.

callback
AsyncCallback

The asynchronous callback delegate invoked when the call is complete.

asyncState
Object

The state associated with the asynchronous call.

Returns

IAsyncResult

The IAsyncResult that references the asynchronous resolve operation.

Exceptions

ArgumentNullException

The address, contract, or callback is null.

Remarks

The default settings on the System.ServiceModel.Description.MetadataExchangeClient are used to retrieve the metadata and the default System.ServiceModel.Description.MetadataExchangeClientMode is MetadataExchangeClientMode.MetadataExchange.

To download metadata but not resolve the information into ServiceEndpoint objects, use the System.ServiceModel.Description.MetadataExchangeClient directly.

Note

An empty collection is returned if no endpoints were imported or if no endpoints matched the contract. If an empty collection is returned, a warning trace is written.

This method requires that you specify a contract type. You can specify the contract by declaring the service interface in the client code or by using a WCF client generated by Svcutil.exe. If the interface changes (adding a new operation, for example) you must update the interface in the client code or generate a new WCF client. If you do not, an exception is thrown. For example, you have a service that implements a service contract called ICalculator that defines Add(), Sub(), Mult(), and Div(). You create a client application and generate WCF client. You then add a method to ICalculator called Echo(). If you then write an application that calls Resolve(Type, EndpointAddress) without generating a new WCF client you get the following exception.

Unhandled Exception: System.ServiceModel.Description.WsdlImporter+WsdlImportException: Cannot locate operation Echo in Contract ICalculator.
