Arction.WPF.LightningChartUltimate 5.5 Stability Issue

[msb]

Hi,
I'm experiencing an issue which is causing the runtime to terminate our application. We are in the process of upgrading from an earlier LightningChart version 4.2.2. We plot "live" acquisition data to the control in this case 4-12 channels. Appears the crash occurs when we change plotting modes or perform a scale change when acquisition in running. This appears to happen intermittently but frequently as it's easily re-creatable.

Thanks,

Hello,

this multithread-vertex buffer issue was fixed in LC v.6.0.1. Please update to that.

Another engineer attempted to upgrade to 6 but found the changes incompatible with our current application, as it wasn't close to being a functional system afterward. We would be more comfortable on 5.5 with a patch available to us as we are nearing the end of our development cycle and are completing our integration testing.

We have a .NET4 assemblies pack available which has the fix included.
