We are pleased to announce a stability update to SciChart. Version 2.2 includes many fixes and improvements for issues which you have reported on the forums over the past 6 weeks.

Please see the changelog below. It is recommended to update to the latest version if you are experiencing one of the issues listed below:

SciChart v2.2.3123 Release What’s New (23rd September 2013)

Breaking Changes

  • SciChart DLL now named with version name, you can reference two versions of SciChart in the same solution. This will require that you update your csproj files to reference the new DLL name.

    This feature allows you to install multiple versions of SciChart on the same machine and upgrade project by project (Previously SciChart.Wpf.Dll was overwritten by a new version in the output folder, causing FileLoadException).

    In order to minimise namespace pain we strongly recommend using the xmlns:s=” http://schemas.abtsoftware.co.uk/scichart “, in your XAML files, then xml namespaces are no longer assembly filename dependent.
