Whats new in WCF


Kalpana (1948) is a Bollywood movie from a time before the term had been invented. This 155-minute-long black-and-white feature film gives full rein to the talents of choreographer Uday Shankar, the films director and a legend of Indian dance. The film is about a young dancer who dreams of founding his own dance school, played by the director himself. Despite living until the age of 76, Kalpana is the one and only film Uday Shankar directed in his entire career. In the dance world, however, he will be remembered as a veritable master of the art of choreography. Kalpana will be screened at Cannes Classics on Thursday 17th May at 19:30, Salle Buuel.After ..6.40

Far from the world of Indian dancing, After the Curfew (1954) has as its backdrop the post-war period in Indonesia. In the months following independence, Iskandar returns to civilian life. For this medical student it is a time of bitter disillusionment, as he sees corruption and political incompetence take hold throughout the country. The director, Usmar Ismail, is considered as one of the forefathers of Indonesian cinema. He made a major contribution to the development of Indonesian cinema in the 1950s by founding Perfini, the countrys first film studios. After The Curfew will be screened at Cannes Classics on Thursday 17th May at 17:15, Salle Buuel.

Standard endpointsWCF 4 also comes with several preconfigured standard endpointsThese cover some of the most common usage scenariosYou can simply reuse them as-is without changeYou refer to standard endpoints by name using the kind attributeMakes it easier to get up and running in certain scenarios

preconfigured Standard endpoints in v4.0Standard endpoint nameDescriptionmexEndpointDefines a standard endpoint for MEX configured with IMetadataExchange for the service contract, mexHttpBinding as the default binding (you can change this), and an empty address.dynamicEndpointDefines a standard endpoint configured to use WCF Discovery within a WCF client application. When using this standard endpoint, an address is not required because during the first call, the client will query for a service endpoint matching the specified contract and automatically connect to it for you. discoveryEndpointDefines a standard endpoint that is pre-configured for discovery operations within a client application. The user needs to specify the address and the binding when using this standard endpoint. udpDiscoveryEndpointDefines a standard endpoint that is pre-configured for discovery operations within a client application using the UDP binding at a multicast address.Derives from DiscoveryEndpoint.announcementEndpointDefines a standard endpoint that is pre-configured for the announcement functionality of discovery. The user needs to specify the address and the binding when using this standard endpoint. udpAnnouncementEndpointDefines a standard endpoint that is pre-configured for the announcement functionality over a UDP binding at a multicast address. This endpoint derives from announcementEndpoint.workflowControlEndpointDefines a standard endpoint for controlling execution of workflow instances (create, run, suspend, terminate, etc).webHttpEndpointDefines a standard endpoint configured with WebHttpBinding and WebHttpBehavior. Use to expose REST services.webScriptEndpointDefines a standard endpoint configured with WebHttpBinding and WebScriptEnablingBehavior. Use to expose Ajax services.
