The previewer process exited unexpectedly - No rendering system configured

[rehakmatej]

Hello everyone. I have a problem with using of Oxyplot.Avalonia. The previewer is not able to render the window defined in .axaml file. This happens in original solution downloaded from this repository while the whole solution is able to build and run. I set the SimpleDemo as a startup project, built them and tried to run them and everything works correctly. Next when I open MainWindow.axaml the previewer shows error message. Below is the output from Avalonia Diagnostics. I tried to delete bin and obj folders and build the project again, but it did not help.

Next I have created my own project with OxyPlot.Avalonia and same thing happens. I thought that this is problem of AvaloniaUI, so I decided to download samples from AvaloniaUI repo, tried to run them and the previewer works correctly.

The most interesting thing is exception message "No rendering system configured", so my question is how to avoid this exception?

Thank you

I just ran into this issue as well.

According to #58, nuget consider 2.1.0 is newer than 2.1.0-Avalonia11. You need to use the latest version of the repo as a subproject or manually select the version as 2.1.0-Avalonia11 on nuget.
