My 10-Year Challenge - WriteableBitmapEx turns 10 with v1.6

It was 2009 when I started my first open source project and announced it with this unspectacular blog post. Back then it was developed with Visual Studio 2008 targeting Silverlight and hosted on CodePlex.
Many things have changed and tech comes and goes but during the last 10 years I always adapted, extended it, added bug fixes and reviewed/merged Pull Requests. Even after all the years WriteableBitmapEx is still quite popular, especially with Windows desktop WPF developers.

Version 1.6.2 of WriteableBitmapEx finally adds dedicated libs for UWP and an UWP sample. For WPF it now supports .NET Core, both the .NET Framework and .NET Core libs are part of the NuGet pack.

If you are using the source code and the VS solution directly, you can choose the .NET Framework 4.5 or .NET Core 3 as the target in the VS drop-down.

WriteableBitmapEx supports a variety of Windows platforms and versions.
WPF and Windows 10 Universal Windows Platform (UWP) are actively maintained.
Silverlight, Windows 8/8.1 WinRT, Windows Phone WinRT and Silverlight 7/8/8.1 are not maintained anymore but the latest stable libs are still part of the NuGet package.

You can download the latest via the updated NuGet package. The packages contain the WriteableBitmapEx binaries. All samples and the source code can be found in the GitHub repository.

A huge shout out and thank you to all the contributors, bug issuers and users of the library. ❤
