Internal SciChart Exception in getting Scichart to work with Visual Studio 16.3 (2019) and .NET Core 3.0.

I was able to develop and run everything using the scichart alpha build from Jun 11th.
This includes SciChart2D, SciChart3D, with a minor error.
I was using .NET Core 3.0 Preview 6+, Visual Studio 16.3 Preview on a Win7 box.

However, the client wants to upgrade to Windows 10.
So I installed Visual Studio 16.3 (2019), and .NET Core 3.0 and I was able to build all the packages etc.

However, when launching the WPF part of the application, I was at first encountering AccessViolation exceptions in CreateRenderTarget().

I removed all my SharpDX components, and tried again. I was able to get around this problem by using a version of SciChart 6.0 greater than the Jun 11th alpha version – v. 6.0.0.12382-alpha.

I can now load SciChart2D package.

However, SciChart3D is now throwing null reference exceptions when loading. I’ve included the screenshot. This occurs even with the 6.0.0-beta version.

Please advise.
