title: Need to compare C# source code with dlls
body: <p>We were using a product from a vendor provided to us in form of dll's. Now we are taking over that vendor product's source code. Our core application is dependent on those vendor provided dll's. We want to make sure that the source code that is provided to us is the same as of the dll's we are using. Otherwise our code can break and that could cost us big time. Can anyone please suggest a tool or a way we can compare the source code with dll's.</p>
  
  <p>One way is that we can compile and publish the dll's and then compare the dll's, but that is going to be a huge task as there are multiple packages included in the base product including some aspx and html pages. We are looking for a quick and clean way to perform the task.</p>
  
  <p>Any help 'd be much appreciated. Thanks</p>
