WPF with SciChart in the separate AppDomain

I’m trying to run my WPF with SciChart aplication in the separate AppDomain, but method SciChartSurface.SetRuntimeLicenseKey() is not working for me – no any exception, but in SciChart control I can see “Sorry! Your trial of SciChart has expired. Please contact sales if you require an extension.” instead of Chart.

In the default AppDomain it works fine.

I tried to run SetRuntimeLicenseKey method from both AppDomains – Default and separate, but without luck.
