In this blog post I am presenting a simple validation framework that you can reuse in your code. Also I will be putting here two code snippets that will make it easier for you to add preconditions to your code.

When Visual Studio 2010 was first realeased, one of the features that I expected the most was code contracts. Unfortunately after including them in one of my large projects, it became more clear that at this moment it is not mature enough to be used. Build time increases rapidly when having a lot of source code files and using the code contracts. Enabling static contract validation is even worse, almost doubling the build time on an average development machine.

All that being said, I really like the code contracts way of specifying preconditions. Most of the time I don’t use post-conditions, but being able to specify validation criteria means that the code will be more robust.

I am a big fan of the DRY principle. This means that whenever I can do something that can be reused with minimal or no effort, I try to do it. Recently I’ve started developing a REST framework for our projects, which is not based on WCF (will blog about this too). One of the most problematic areas is how to create service proxies easily without having to duplicate loads of code, but at the same time maintain maximum flexibility. After going through several options, the most attractive is creating a Visual Studio custom code generator.

Since there are almost no resources (and the existing ones are very blurry) I’ve decided to create a series of blogs that will be a guide to creating custom code generators, followed by some other posts with real examples and solutions to problems.

The series is divided into four parts:

Part I (this one) – creating a Visual Studio Package

Part II – creating and registering a code generator

Part III – generating code & debugging

Part IV – creating the setup project and deploying the package

*DISCLAIMER* – Even if everybody is in the new VS2010 hype, I still think there are a lot of developers that are and will be working in VS2008 for a while.
