WSDL Merger
Working with Web Services is supposed to be interoperable, but that's not quite 100% true, there are always some glitches when working with other platforms.
Recently I faced one of those. With .Net I could easily create and consume web services by using WSDLs that had imports, but it seems that some tools don't support that keyword so I had to merge all the generated files (wsdl and xsds) into a single one.
Searching a little bit in live.com (https://search.live.com/results.aspx?q=%22wsdl+merger%22) I found a link to a post that had a really simple tool (and really helpful) to do the task.
