title: Open Source .net/C# projects and Frameworks?
body: <p>I know that with .net you have Asp.net, and I know that .net it's self is a framework. How ever, I am coming from the land of Java and PHP where frameworks are aplenty.</p>
  
  <p>I understand that C# and .net are usually used in business development ans that a lot of the code is not open due to the nature of MS and the platforms used to develop with such technologies.</p>
  
  <p>I have scoured "C#" on github and ".net" on the same site, how ever the code bases I find, seem to be developed for a while and then fade away, and it also seems, chime in if I am wrong, that there are no frameworks for .net, aside from .net it's self. With that said I have seen Spring .net</p>
  
  <p>The reason I ask is because I have recently began reading the Framework Design Guidelines book  which is mostly discussing .net and .net frameworks, how ever when looking for examples on .net frameworks used in production code, I am either blind or there are none.</p>
  
  <p>Are there any? If I was to develop an application is there any frameworks I could draw on aside from .net it's self.</p>
  
  <p>The application could be desktop, database driven, web.....I am just looking to see what .net frameworks exist and how they are used to get a better understanding of this "closed source" world.</p>
