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


Good evening!
I wrote a test program with your library, the following situation arose:
On Windows 10 everything works fine, and on Windows 7 the following error (for 3D Charts)

XamlParseException: The invocation of the constructor on type 'SciChart.Charting3D.SciChart3DSurface' that matches the specified binding constraints threw an exception.

I ran the SciChart WPF Examples Suite program and saw the same message.

Please tell me what to do (preferably without a new version, I read that only SciCharts 5 work stably for Windows 8 and below)

System Information:
Windows 7 64-bit, 8GB RAM, 1TB SSD, .NET Framework 4.5.2
SciCharts: Version

in version the situation is similar

Hi Aleksandr,

Thanks for your inquiry.
Please note that Microsoft has stopped supporting Windows 7 on January 14, 2020. Please take a look:

That means we are also stopping supporting this OS, as it’s deprecated.
However, you can submit a support ticket here and attach a small sample project reproducing the issue. We will try to investigate it and help you.

With best regards,
