انتشار PostSharp 6.0 RC
PostSharp 6.0 is the biggest refactoring since the 2.0 version released in July 2010. For a good cause: PostSharp 6.0 now runs natively in .NET Core 2.0. Previous versions of PostSharp executed only under .NET Framework at build time and the support for .NET Core was achieved by using a load of hacks that ended up being unmaintainable, warranting this big refactoring.
Let’s have a look at the new features of PostSharp 6.0 :
- Support for .NET Core 2.0-2.1 and .NET Standard 2.0.
- Support for Portable PDB.
- Support for C# 7.2.
- Ending the PostSharp versioning hell side-by-side: backward compatibility within the same major version.
- Logging: robustness to faults in the logging subsystem.
- Logging: no need to initialize before the first logged method is hit.
- Caching: preventing concurrent execution (locking).
- Visual Studio tooling: support for the new CPS-based project systems.
- GDPR compliance: we no longer collect your name and email for trial, nor use unsecure HTTP, nor use non-resettable user id hashes.

longer importantIt is quite a possible situation to have a user navigating to the client application’s page that sends an HTTP request to the server. While our app processing the request, a user can navigate away from that page. In such a case, we want to cancel the HTTP request since the response is no to that user.
