WCF Tutorial - Basic Interprocess Communication

Posted By: Amit Mehra     Posted Date: December 14, 2009    Points: 2   Category :Others
What the heck is WCF? For a long time, I couldn't tell you exactly what it was. And honestly, I still don't think I can. WCF is such a broad concept that it's hard to boil down into a concise explanation. When I finally started reading about it, and getting beyond the concepts, things started to clear up. That's what today's tutorial is about - cutting through all the concepts and just use WCF to build a basic server and a basic client.

Using Serialization/Deserialization versus flat file for Interprocess Communication?


I have a process A that gathers data and hands it over for processing to process B. The amount of data is anywhere near 650MB or more, the transport should be as fast as possible, yet painless (if possible). A and B are different processes, so the scenario could be considered Inter Process Communication.

Here is what I've done and found so far:

  1. Process A created an object filled with all information and serialized it into a file. B deserialized and processed the data.
    - the computational time on the serialization is OK.
    - the deserialization is many times bigger than serialization to the point that I consider it useless because it takes too long.
  2. I do not serialize/deserialize instead use a flat file for the communication.
    - it's quick and same speed for read and write
    - lacks flexibility and is not very elegant either.
  3. I used namedPipes to transfer the serialized object between processes A and B, which is elegant but ever slower because of the issue in #1 and the fairly poor performance of namedPipes and big data?



  1. Can somebody please advise me on how to best deal with my requirements?
  2. Explain to me why deserialization is soooo slow (I understand that depending on type a lot of object have to be created) and what better approach one should take.

Windows Communication Foundation ( WCF ) Tutorial

Performance comparison between distributed technologies:

When we migrate distributed applications made with ASP.NET Web Services, WSE, .NET Enterprise Services and .NET Remoting to WCF, it will in almost all cases result in a performance boost:

SQL Injection Walkthrough / Tutorial

SQL Injection is a trick to inject SQL query/command as an input possibly via web pages. Many web pages take parameters from web user, and make SQL query to the database. Take for instance when a user login, web page that user name and password and make SQL query to the database to check if a user has valid name and password. With SQL Injection, it is possible for us to send crafted user name and/or password field that will change the SQL query and thus grant us something else.

SharePoint Tutorial - Web Parts

A page in SharePoint is comprised of web parts the exist within zones. Web parts are available for just about everything. For example in the page below there are four web part highlighted by different colors. The purple web part displays a short list of the new announcements stored in the annoucements library. The pink web part displays events from a calendar within the site. The green web part displays an image from a location the user specifies. The gray web part displays a list of links from the links list on the site.

SharePoint Tutorial - Team Sites

Team sites are small web sites that are created to store everything about a particular thing. For example a site can be created for a department in an organization like human resources. I site can be created for a particular project. A site can even be created for a meeting. Everything about the thing (department, project, meeting) like documents, lists, calendars, etc. is stored in that site.

SharePoint Tutorial - Libraries

A library is a feature in SharePoint that stores files (documents). Think of a library as a folder on your file system. For example, a library can be created to store resumes in the human resources team site. A library is usually created for a specific type of file. Libraries can contain metadata to describe the particular file in more detail and to make it easier to find.

SharePoint Tutorial - Lists

A list is a feature in SharePoint that stores a lists of information. For example, a list can be created to store web links in the human resources team site. A list is usually created for a specific type of information. Lists can contain metadata to describe the particular information in more detail and to make it easier to find.

SharePoint Tutorial - Security

Security in SharePoint is comprised of users, groups and roles.

Users, Groups and Roles

A user account comes from the authentication system. For example, if Active Directory is used to authenticate then the user accounts will come from it.

There are two types of groups SharePoint uses: domain groups and SharePoint groups.

SharePoint Tutorial - SharePoint Logical Architecture

The SharePoint logical architecure consists of nested and isolated levels. These levels provide benefits for security, navigation, search, branding and ect. depending on the level

SharePoint Farm
The base level for any SharePoint implementation is the SharePoint farm. Physically a farm can consist of one server or many servers. An organization may implement one or more farms. This usually depends on security and performance needs.

SharePoint Tutorial - Content Types

SharePoint content types provide users with a way to manage and organize content in a more meaningful way. It's a reusable of settings you want to apply to a particular type of document in a library or item in a list.

SharePoint Tutorial -SharePoint Physical Architecture

The SharePoint physical architecture consists of services running on one or more servers.

There are three types of services that together run the SharePoint farm: web, application and database services. Web services through Internet Information Server is what processes the ASP.Net and sends back the html to a user's browser. Application services is where the "brains" of SharePoint are located. All of the SharePoint specific logic and services are processed there. Database services are run by SQL Server and it's where all the data/content for SharePoint is stored.

The Class Diagram

The class diagram is core to object-oriented design. It describes the types of objects in the system and the static relationships between them.

WCF Tutorial - Events and Callbacks

we described how to make a very simple client/server application where clients would call functions on the server through a shared interface. In this tutorial, I'm going to expand that application to allow the server to execute functions on the client by using callbacks. Essentially, this is WCF's mechanism to allow events to be raised from the server to it's connected clients.

Getting Started with Windows Communication Foundation

Windows Communication Foundation (WCF) provides a unified framework for rapidly building service-oriented applications that makes it easy to build and consume secure, reliable, and transacted Web services. It unifies the capabilities in ASMX, WSE, Remoting, COM+, and MSMQ; therefore developers need to learn only one programming model.

The GridView control is a powerful tool and is simple to implement.

First, you will need to import the System.Data.SqlClient namespace.

How to run Office macros by using Automation from Visual Basic .NET

This step-by-step article describes how to call Office macros from a Visual Basic .NET Automation client.

You can use Microsoft Office Automation to open a document or create a new document that contains a Visual Basic for Applications (VBA) macro and execute the macro at run time.
