  A new release of Code Contracts is now live. And we almost made our once-a-month release schedule! This is mostly a release that fixes a lot of problems reported on the forum. Check out the release notes for the details.
  
  Please keep using the forum to let us know how you're using Code Contracts and what problems you're running into. Of course, we'd be thrilled to hear of any success stories too.
  
  And we'll be at PDC 2009! We'll be having a session along with Pex and also a demo booth. If you're going to PDC (and of course you should), please come by and see us.

• Welcome to Code Contracts for .NET

  Mike BarnettMSFTFreitag, 20. Februar 2009 02:28
  We are so happy that you are interested in Code Contracts! You are at exactly the right place for learning how to use contracts from any .NET language to:
  

  • Specify method preconditions for expressing conditions that a caller must meet in order to call a method.
  • Specify method postconditions for expressing conditions that the implementation of a method must meet before returning. Conditions can be specified for both normal termination as well as exceptional termination.
  • Specify object invariants that describe the healthy states for an instance of a class.

   

  We currently provide three tools for making use of contracts:

  • A binary rewriter that operates as a post-build step to inject the contracts into the appropriate places for them to be evaluated at runtime.
  • A static checker that operates as a post-build step to analyze your code without even executing it for potential contract violations.
  • A documentation generator that adds information about the contracts to the XML documentation files for your project.

  The installer for these tools is available for either commercial or non-commercial use.

  We welcome you to use the forum to ask questions about how to use contracts and the tools, to make suggestions for how we can improve, and --- if you really must --- to report bugs and problems.
