Breaking Changes in PostSharp 5.0
PostSharp 5.0 contains the following breaking changes:
The OnMethodBoundaryAspect aspect will now advise the state machine of async methods and iterators by default instead of the kick-off method. The ApplyToStateMachine property is deprecated in favor of SemanticallyAdvisedMethodKinds and its default value is now true. The behavior of existing code that ignored the PS0215 warning will silently change.
The PostSharp.Reflection.Syntax namespace has been renamed PostSharp.Reflection.MethodBody and classes inside this namespace have been renamed to reflect the fact this namespace is definitively not a syntax tree. (We were tired to apologize for this misnaming.) You must modify your code (hopefully just a few files) otherwise it will no longer build.
The PostSharp.MessageLocation class has been moved to the PostSharp.Extensibility namespace. You must modify your code (hopefully just a few files) otherwise it will no longer build.
The PostSharp.Patterns.Diagnostics has been completely revamped. See Upgrading from PostSharp Diagnostics 4.3 for details. You must modify your code (hopefully just a few files) otherwise it will no longer build.
The GenericArgs family of classes, a legacy from PostSharp 1.5 that no longer worked, was deleted.
It is no longer allowed to add an aspect or an advice to an anonymous method or to a method of a compiler-generated type, including the MoveNext method of a state machine type. To avoid the error, implementations of IAspectProvider and pointcuts should use method.GetSemanticInfo().IsSelectable to determine whether a method is a valid aspect or advice target.
The PostSharp.IgnoreWarningAttribute class has been renamed SuppressWarningAttribute and moved to the PostSharp.Extensibility namespace. You will get an obsolescence warning until you modify your code.
Silverlight, Windows Phone and WinRT are no longer supported. These projects will no longer build.
Xamarin is temporarily unsupported. These projects will no longer build. Please contact our support team if you are affected by this change.
PostSharp Professional has been renamed PostSharp Framework and no longer includes PostSharp Diagnostics. Please contact our sales team if you have a PostSharp Professional license and rely on PostSharp Diagnostics.
PostSharp Express has been renamed PostSharp Essentials is no longer compatible with PostSharp Express 4.2 and earlier. The licensing of PostSharp Express was modified in PostSharp 4.3, but PostSharp 4.3 included a backward-compatibility licensing mode. It has now been disabled.
Use of the license server is now restricted to the new PostSharp Enterprise license. Please contact our sales team if you are affected by this change.
Please contact our sales team if you are a commercial user and are affected by the licensing changes. We will find a solution that is acceptable for both.
