I've been doing a lot of research lately about SOA and ESB's etc.

I'm working on redesigning some legacy systems at work now and would like to build it with more of a SOA architecture than it currently has. We use these services in about 5 of our websites and one of the biggest problems we have right now with our legacy system is that almost all the time when we make bug fixes or updates we need to re-deploy our 5 websites which can be a quite time consuming process.

My goal is to make the interfaces between services loosely coupled so that changes can be made without having to re-deploy all the dependent services and websites.

I need the ability to extend an already existing service interface without breaking or updating any of its dependencies. Have any of you encountered this problem before? How did you solve it?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
Finding a Relative Path in .NET

Here’s a nice and simple path utility that I’ve needed in a number of applications: I need to find a relative path based on a base path.
