Previous changes from v1.10.10126.2

  • Summary

    🚀 This is the first major community-driven release of the DotNet CodeContracts. This release addresses a lot of pending issues with installer, new IL patterns introduced by Roslyn Csc compiler, and more reasonable implementation of the postconditions in async methods, a lot of changes in the BCL contracts and more.

    📦 Nuget Package

    📦 DotNet.CodeContracts at nuget.org

    👌 Improvements and new features

    • Proper implementation of async methods postconditions. Now async postconditions are implemented via call to ContinueWith method that checks a postcondition only when task finishes successfully (more details at #278).
    • 🔀 Postcondition for async method now runs synchronously to reduce additional overhead (#275).
