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).

Updated contracts for BCL types

  • Added missing contracts in System.Linq.Expressions.Expression (#171)
  • Contracts for System.Reflection.CustomAttributeExtensions (#180)
  • String.IndexOfAny contract incorrect (#200)
  • False contract assumption encountered on System.Decimal.op_Explicit (#203)
  • Added missing contracts in Directory class (#251)
  • Add missing contracts in System.Windows.Input.InputManager (#285)
  • Add missing contracts in System.Windows.Data.MultiMinding (#286)
  • Extend postcondition on Path.GetTempFileName (#305)
  • Contracts for System.Version (#318)
  • Contract reference assemblies for .NET Framework (#291)
  • Update System.Threading.Tasks.Task for NET4.5/4.6 (#296)
  • Add contracts for System.OperatingSystem (#306)

  • ccrewrite produces an incorrect type name in
  • Static checker can't prove ForAll on Roslyn-compiled inline arrays (#204)
  • BadImageFormatException when using Contract.Ensures in async method, that returns task without any await (#235)
  • NullReferenceException in ccrewrite-generated code (#191)
  • Contract.Require(x != null) gets translated in!(x <= null)` in the documentation rewritten by CC (#307)
  • Using capturing precondition in async method in struct lead to invalid IL (#168)

Other bug fixes

  • Malformed Contract. Found Requires after assignment (#29)
  • Bad application of visibility rules on method parameter attribute (#273)
