I've been using BinaryFormatter.Deserialize in a project for quite some time.
Today, after updating from 22.214.171.124 to 126.96.36.199 I started getting System.NullReferenceException when using the BinaryFormatter.Deserialize to deseralize a HashTable. I've had to roll back to 188.8.131.52.
We might have inherited a recent mono bug while updated the BCL. Sadly it means that case was not covered by some unit tests (or used in our test applications).
Can you attach a small test case (unit test or a small app) that shows the issue. We'll fix this and ensure it gets part of the test suite. Thanks!
Also do you remember if the NRE occured:
* only occured on the simulator ?
* did the same happen on devices ?
It was in the simulator.
If it works in release (not debug) build for the simulator (or on devices, debug or release) then it's likely a duplicate of bug #14493
Can you try this ? or supply a test case so we can validate this ?
We will try to provide a test case. We are working hard to meet a deadline for a demo and are currently using Version 184.108.40.206 of Xamarin.
I understand, no rush. When you have the time try first 6.4.5 which has a fix (the single fix for that release) for a very similar problem (bug #14552).
Setting back to NEEDINFO (which means we, Xamarin, are waiting on more information on the bug).
I installed 6.4.5 and the issue went away. Thank you.
