Microsoft Enterprise Library: Part-II

This post is in continuation to the series started for exploring the Enterprise library here. This post will cover in detail the newly introduced Unity Application Block.


Before we start the discussion there are few concepts that need to be understood for getting a good grasp of the Block.

Inversion of Control (IoC): It means that objects do not create other objects on which they rely to do their work. Instead, they get the objects that they need from an outside source.

Dependency Injection (DI): It means that this is done without the object intervention, usually by a framework component that passes constructor parameters and set properties.

More about DI can be found here

IOC is implemented using DI (Dependency injection).

IOC is a principle while DI is a way of implementing IOC. In DI we have four broader ways of implementing the same:

• Constructor way

• Exposing setter and getter

• Interface implementation

• Service locator


These two concepts forms the basis of this block and more details about these can be found here. (Although it takes JAVA as the language, the concept is applicable to .Net and any other language that implements these patterns).


MSDN has a great article for introduction to Unity
More about the Unity Block can be read here

Asp.Net 4.0: An Overview-Part-III

This is the last post in the series which will explore the following new features of ASP.Net 4.0  Performance Monitoring for Individual Applications in a Single Worker Process Web.config File Refactoring Permanently Redirecting a Page Expanding the Range of Allowable URLs Performance Monitoring for Individual Applications in a Single Worker Process It is a common practice to host multiple ASP.NET applications in a single worker process, In order to increase the number of Web sites that can be hosted on a single server. This practice results in difficulties for server administrators to identify an individual application that is experiencing problems. ASP.NET 4 introduces new resource-monitoring functionality introduced by the CLR. To enable this functionality, following XML configuration snippet is added to the aspnet.config configuration file.(This file is located in the directory where the .NET Framework is installed ) <?xml version="1.0" encoding="UTF-8...

WCF..Why Communication Foundation?

WCF (Basics..for building effective Services) WCF:  Windows Communication Foundation It includes a collection of of .NET distributed technologies that have existed for long , but never got grouped under one name. WCF can be considered as collection of the following technologies. Web Services(ASMX) NET Enterprise Services MSMQ .NET Remoting Code written in WCF can interact across components, applications and systems. WCF is in accordance with SOA (Service Oriented Architecture). Following Sections provide the details of these ABCs. Addresses In WCF, every service has a unique address. The address provides two important elements A)     Location of the service B)      Transport protocol or transport schema used to communicate with the service.  The location indicates the name of the target machine, site, or network; a communication port, pipe, or queue; and an optional specific path or URI. WCF supports th...

WCF-REST Services-Part-II

HOW REST is implemented in WCF Part-I of the series explored the REST conceptually and this post will explore how REST is implemented in WCF. For REST implementation in WCF, 2 new attributes namely WebGetAttribute and WebInvokeAttribute are introduced in WCF along with a URI template mechanism that enables you to declare the URI and verb to which each method is going to respond. The infrastructure comes in the form of a binding ( WebHttpBinding ) and a behavior ( WebHttpBehavior ) that provide the correct networking stack for using REST. Also, there is some hosting infrastructure help from a custom Service¬Host ( WebServiceHost ) and a ServiceHostFactory ( WebServiceHostFactory ). How WCF Routes messages WCF routes network messages to methods on instances of the classes defined as implementations of the service. Default behavior ( Dispatching ) for WCF is to do this routing based on the concept of action. For this dispatching to work, an action needs to be present in ev...
