Peer to Peer File Sharing Through WCF. Table of Contents Introduction The lack of resources as though computing, storing and data resources, leads to this idea that we can use the huge and infinitive resources which potentially exists in the computers of users throughout the world. For instance, we can use the computing resources of PCs which most of the time are workless, on the other hand, we can use the huge amount of data which have been stored in the computers. Moreover, we can employ these amazing resources to connect straightaway and use their data instead of connecting to a centralized server and satisfying our needs. When we want to work over the centralized architecture, some problems come to the fore and passing time makes those problems tougher and tougher, then these growing problems necessitate us to switch to the more high-powered hardware, infrastructures and the like.
Consequently, we have to use higher bandwidth and stronger servers and likely super computers which cost us high-priced outlays. Background. WCF tutorial. Guide to the Documentation. Juval Lowy on Interface Based Design | ARCast.TV. WCF Concurrency (Single, Multiple and Reentrant) and Throttling. 3 Ways to Do WCF instance Management (Per call, Per session and Single) Introduction Many times we would like to control the way WCF service objects are instantiated on WCF server. You would like to control how long the WCF instances should be residing on the server. WCF framework has provided 3 ways by which we can control the WCF instance creation. In this article we will first try to understand those 3 ways of WCF service instance control with simple code samples of how to achieve them. Finally we will compare when to use under what situations. This is a small Ebook for all my .NET friends which covers topics like WCF,WPF,WWF,Ajax,Core .NET,SQL etc you can download the same from here or else you can catch me on my daily free training @ from here WCF service object instancing basics In a normal WCF request and response communication following sequence of actions takes place:- WCF client makes a request to WCF service object.WCF service object is instantiated.WCF service instance serves the request and sends the response to the WCF client. intCounter++
Every Class a WCF Service with Juval Lowy | ARCast.TV. WCF Programming for Beginners. Windows Communication Foundation (WCF) Windows Communication Foundation (WCF) is a dedicated communication framework provided by Microsoft. WCF is a part of .NET 3.0. The runtime environment provided by the WCF enables us to expose our CLR types as services and to consume other existing services as CLR types. Background: In the world there are a lot of distributed communication technologies that exist. Some of them are: ASP.NET Web Services (ASMX) Web Services Enhancements (WSE) Messaging (MSMQ) .NET Enterprise Services (ES) .NET Remoting Creating and Consuming a Sample WCF Service: Three major steps are involved in the creation and consumtion of the WCF services.
Create the Service. In WCF, all services are exposed as contracts. Service ContractThis contract describes all the available operations that a client can perform on the service..Net uses "System.ServiceModel" Name space to work with WCF services. [ServiceContract] public interface IFirstWCFService [OperationContract] return x + y; Windows Communication Foundation (WCF) Browse by Tags All Tags » Windows Communication Foundation (WCF) (RSS) I just went to the session "Windows Communication Foundation: Building Secure , Reliable and Transacted Distributed Services" by Shy Cohen, that brought a very good overview of the different aspects to building great services with all the quality attributes...
Introduction In the introductory post of this blog series, I explained our mission statement: the creation of a POP3 tunnel over SOAP/HTTP using WCF. The first part of the implementation was covered in part 1 of this blog series: "A simple POP3 client... Introduction In my previous post you learned about this POP3 tunneling idea using WCF. Introduction Lately I've been quite annoyed by the fact that some hotspots and other public networks block some "common ports", like the POP3 port TCP/110. More Posts. WCF Data Services. WCF Data Services uses the OData protocol for addressing and updating resources. In this way, you can access these services from any client that supports OData. OData enables you to request and write data to resources by using well-known transfer formats: Atom, a set of standards for exchanging and updating data as XML, and JavaScript Object Notation (JSON), a text-based data exchange format used extensively in AJAX application.
WCF Data Services can expose data that originates from various sources as OData feeds. Visual Studio tools make it easier for you to create an OData-based service by using an ADO.NET Entity Framework data model. WCF Data Services also includes a set of client libraries, one for general .NET Framework client applications and another specifically for Silverlight-based applications. WCF Data Services Overview. WCF Data Services enables creation and consumption of data services for the Web or an intranet by using the Open Data Protocol (OData). OData enables you to expose your data as resources that are addressable by URIs. This enables you to access and change data by using the semantics of representational state transfer (REST), specifically the standard HTTP verbs of GET, PUT, POST, and DELETE.
This topic provides an overview of both the patterns and practices defined by OData and also the facilities provided by WCF Data Services to take advantage of OData in .NET Framework-based applications. In OData, you address entity resources as an entity set that contains instances of entity types. For example, the URI returns all of the orders from the Northwind data service that are related to the customer with a CustomerID value of ALFKI. OData defines a set of extensions to the Atom Publishing Protocol (AtomPub). Concepts.
