SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and iOS Chart & Android Chart Components

I’m evaluating SciChart v6.1 for a WPF realtime charting application.
So far everything has worked well, except some issues with very slow loading.
On my machine, any app referencing SciChart takes around 5-6 seconds to initialize before the app can continue loading.

Some debugging with dotTrace shows most of the time is spent in the constructor of SciChartSurface calling the Charting2DNativeDllsLoader constructor.

dev machine is Windows 10 Pro x64, core i7, 32GB ram
Visual Studio 2019 Pro
To duplicate create new WPF application, .NET Framework v4.8
In MainWindow constructor add two lines:

SciChartSurface.SetRuntimeLicenseKey("[TRIAL KEY]");
var tmp = new SciChartSurface();

Executing the second line takes around 5-6 seconds.
I have uploaded a sample project that duplicates this issue and dotTrace result.
Let me know if I can provide any other info.
