I've opened issue on github, but no response yet. Possibly someone here knows a workaround...
The problem is that "XamarinClient.Android" project hangs on connection attempt. I've tested it on my device with Android 8.1.
The problem is in the file Opc.Ua.Core/Security/Certificates/DirectoryCertificateStore.cs line 613:
entry.Certificate = new X509Certificate2(file.FullName);
This line of code never finishes. I tried to comment this code, but it hangs further (also when trying to make some manipulations with certificates).
Any ideas what to do with this?
