<p>We are happy to announce that <strong>PostSharp 6.7 Preview</strong> is available today. Included in this release are
  long-awaited support for <strong>Xamarin</strong> and <strong>.NET 5.</strong>&nbsp;The download is available on <a
    href="https://www.postsharp.net/download">our website</a>.&nbsp;</p>

<h2>Xamarin support&nbsp;</h2>
<p>PostSharp has supported .NET Standard for a long time, and that opened the way to bring back the support for Xamarin.
  From 6.7 release you will be able to use PostSharp in .NET Standard projects that can be then referenced in your
  Xamarin application project.&nbsp; The support includes creating custom aspects as well as using PostSharp Pattern
  Libraries.&nbsp;</p>
<p>Note that with Xamarin, we still just support .NET Standard libraries, so you cannot use PostSharp on a project that
  is built for Xamarin. As we write this, we are updating our test suite and running them on physical mobile devices.
  Starting with 6.7, we will run these tests regularly and will guarantee (when 6.7 will be stable) that .NET Standard
  assembly, enhanced by PostSharp, will safely work on Xamarin.</p>
<h2>.NET 5 support&nbsp;</h2>
<p>We are implementing full support for .NET 5, not limited only to .NET Standard projects. We've fixed several issues
  that were preventing building with .NET 5.0 Preview 4 SDK and targeting .NET 5.0 framework. We would be happy if you
  will try to build you own projects using the preview SDK or target .NET 5 in your projects with PostSharp.&nbsp;</p>
<h2>Summary&nbsp;</h2>
<p>PostSharp 6.7 Preview is a release with two main improvements: support for Xamarin and .NET 5.&nbsp;</p>
<p>Please note that this is a <strong>preview release</strong>, so do expect minor problems. We are not fully done with
  testing just yet and we will continue to test our product with more .NET runtimes. Please do get back to us to report
  any problems.&nbsp;</p>
<p>Happy PostSharping!&nbsp;</p>
