I am auditing one big legacy application. I use Visual Studio 2010 modeling projects to visualize the design of this legacy application. When I wanted to get my UML diagrams to image files so I can insert them to documents I found no option for it. As it turned out we have to write extension for modeling projects and deploy it as Visual Studio 2010 extension. Here is the installer and source package of my UML.SaveAsImage extension.

I am trying to implement form based authentication (FBA) membership provider that is able to support multiple authentication mechanisms. Take it as an self-training experiment. In this posting I will introduce bases of my experiment and introduce my current plans and ideas.
Read morePatterns of Enterprise Application Architecture
Lately I finished reading the famous patterns book by Martin Fowler – Patterns of Enterprise Application Architecture. This book introduces and describes design patterns you will usually see when building enterprise applications. There are also examples for patterns and although they are simple and primitive they give you the idea how to implement or use specific patterns. If you are working on enterprise applications every day you will find this book very useful and I’m sure you will use it as manual.
