title: Adding custom information to CSPROJ files
body: <p>As part of our development life cycle we have a number of process that we run against the C# source in our projects.</p>
  
  <p>The processes are driven off a GUI that currently reads the *.csproj file to find the source files used within the project. This works fine.</p>
  
  <p>We now have a new requirement to provide some validation processes that require a call out to a web-service. The web-service needs to be provided with some credentials that are project specific. Ideally we could enter and store these credentials within the *.csproj file but I don't see a means of extending it - is there?</p>
  
  <p>We don't really want to introduce a new config. file just for these settings if we can help it. Is it possible to store information like this is the *.csproj file, if not is there any other place to put it.</p>
  
  <p>thanks</p>
