How many times do we need to understand an application that we did not develop or we develop some time ago and do not remember the dependencies between the different projects within a solution?

Visual Studio 2010 will come with some tools to address architecture understanding, but meanwhile, VS 2008 by default does not come with anything to observe that.

Making a short search, I came accross with this tool that I am going to share: 

Visual Studio Dependencies Manager [ http://www.codeplex.com/vsdm ]

This is a free too, in beta phase that allows to visually see dependencies between projects within a solution, including external assemblies.

Additionally, it allows other things like packaging and publish the .dlls. I only used it for the former.

Despite it has opportunities to be improved, above all graphically, I think it is useful to have a first approach to understand the interdependencies within a solution.

Hope this post is useful. More info in: http://www.codeplex.com/vsdm
