• AutoMapper – A Custom Type Converter That Exposes a Destination Value

  9 January 2011 - 11:45 PM / by Dominic Pettifer. 0 Comments for AutoMapper – A Custom Type Converter That Exposes a Destination Value.

  Cool C# Snippets - Writing a custom ITypeConverter for AutoMapper is easy, just write a class that extends the TypeConverter<TSource, TDestination> abstract type. But it’s possible to supply a pre-instantiated destination object during conversion which the TypeConverter type doesn’t expose.

• How to get a Reference to all Assemblies in the \bin Folder

  14 September 2010 - 12:40 AM / by Dominic Pettifer. 2 Comments for How to get a Reference to all Assemblies in the \bin Folder.

  Technical Article - Something I’ve been stuck on for a while is a reliable way to get a list of all Assemblies (DLL files) that are located in the ASP.NET website’s \bin folder. I’ve frequently needed this for IOC style Controller registration code (find all types in all Assemblies that implement IController for instance), or for my ASP.NET Bootstrapper pattern (find all types that implement IBootstrapperTask). Relying on AppDomain.CurrentDomain.GetAssemblies () can be dangerous as I’ll discuss.

• Static Variable Gotchas - Are Static Variables in Base Classes Shared In Derived Sub Classes?

  29 July 2010 - 11:50 PM / by Dominic Pettifer. 3 Comments for Static Variable Gotchas - Are Static Variables in Base Classes Shared In Derived Sub Classes?.

  Development Gotchas - Something that caught me out recently is the behaviour of static variables in C# classes, and how they behave in derived classes. Also how does this differ with static variables in Generic<T> base classes? Finally, we use this understanding to create a generic base Singleton class.

• Put an IOC Powered Bootstrapper in your ASP.NET MVC Application

  15 July 2010 - 10:30 PM / by Dominic Pettifer. 2 Comments for Put an IOC Powered Bootstrapper in your ASP.NET MVC Application.

  Technical Article - Do you have a fat Global.asax file in your ASP.NET MVC application? Does it contain 1000’s of lines of application start-up code? Want to break it out into separate classes and gain the benefits of decoupling, dependency injection and unit testability? Read on.

• IHttpModule Gotchas – The Init() Method Can Get Called Multiple Times

  10 March 2010 - 11:35 PM / by Dominic Pettifer. 1 Image for IHttpModule Gotchas – The Init() Method Can Get Called Multiple Times. 3 Comments for IHttpModule Gotchas – The Init() Method Can Get Called Multiple Times.

  Development Gotchas - When creating and registering IHttpModules, some people mistakenly think that only a single instance of the IHttpModule is created, and that the Init() method is only called once. I’ll explain how and why this is incorrect, and how this misunderstanding can lead to subtle bugs in your ASP.NET web application.
