Calling Analytics.Client.Flush() when there are pending events can cause deadlock

[tombogle]

This problem is illustrated here: sillsdev/DesktopAnalytics.net#27
To reproduce:

1. Build the SampleAppWithForm project
2. Run SampleAppWithForm
3. Click the Track button
4. Without delay, select the Flush checkbox
5. Click the X to close the window.

The call to Analytics.Client.Flush() never returns, and the window never closes.

I've also seen this in a project, but didn't have consistent steps to reproduce.

Thanks for your report, we start looking into this

Hi @tombogle I tried replicate the issue but I don't have success, could you help us sharing your example project on a public repo, please?

[tombogle]

The repo linked above is public.

Hi @tombogle we identify on which place is the possible issue, we still working on your issue reported

[edsonjab]

Hi @tombogle we created a new LIB that you can use for your project, CSharp in this library fixed the issue.

[tombogle]

Thank you. It might take a few weeks before I get to it, but I will try to retrofit our code to use this new library to see if it solves the problem for us. It's not entirely clear to me why this could not be fixed in the existing implementation. The name of the new library is a bit confusing since it kind of implies that it is for C# only, but the description suggests that it is compatible with .Net applications in general. But the original library already purports to be the one for .Net. How will potential users know when to use Analytics.Net and when to use Anayltics-Csharp?

@tombogle The CSharp LIB is a new LIB that is meant to completely replace .Net and Xamarin. There was more interest in building this new LIB out with newer features as a replacement vs continuing development on the existing LIBs. I do hope it solves your issues, please let us know if you run into anything.

Thank you
