UWP - Chart not rendering in Release mode

[Zulu]

Hi, I'm writing an UWP application to run in a Windows 10 tablet. The project consists in a realtime chart that shows data taken from device.

All works great in Debug mode but when I change to Release, the lines of the chart disappear.

The only error that appear in console is a marshal error due to the RunAsync call to render the chart on the main thread:

Msg:[Failed to marshal with IID={11D3B13A-180E-4789-A8BE-7712882893E6}]

The same error appear also in Debug, but without causing problem to the chart.

I'm using VS 2019 latest release.

Hi Yuvaraj,

thanks for your reply.

I have tested your project and it works correctly in debug and release mode.

So I have tried to import your class in my project and execute them from it. The result is that in release mode your class don't render lines correctly too. At this point I am afraid is a problem due to some configuration in my project.

In response to your request:

• Syncfusion version: 19.2.0.62, the package is Syncfusion.SfChart.UWP
  
• Machine details:
  • Visual studio version: 16.11.3
    
  • Deployment target version: min. Windows 10 1809 (17763) - dest. Windows 10 1903 (18362)
• Additional project settings:
• .NET Native tool chain is enabled
  
• Solution compiled only in x64

Here a snippet of code from my View:

Have you ever faced similar situation? Is there some test I can do or some setting I should set?

I found a solution for my problem, recreate the project!

I create a new solution and import one by one the classes of broken project. Testing it, the chart render correctly in Debug and Release mode.

I don't get where, in the original project the error, start, but at least I managed to resolve my issue.

Thanks for your support!
