lately I'm experiencing crashes when stopping a debug session of an Xamarin.Android project.
Happens randomly but would say at least once a day..
Value cannot be null.
Parameter name: key
The stacktrace is :
at System.Collections.Generic.Dictionary`2.FindEntry(TKey key)
at System.Collections.Generic.Dictionary`2.TryGetValue(TKey key, TValue& value)
at Mono.Debugging.Client.DebuggerSession.RemoveBreakEvent(BreakEvent be)
at Mono.Debugging.Client.DebuggerSession.<>c__DisplayClassb.<Dispatch>b__9(Object param0)
at System.Threading.QueueUserWorkItemCallback.WaitCallback_Context(Object state)
at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)
at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)
Hope this is enough.
Could you please provide some more detailed repro steps to help us identify what might be causing this.
Just to confirm you are using the 4.10.1 Alpha release?
I'm using Xamarin.Android 4.10.01057 (62077ce0).
The crash really is random so hard to give you repro steps.
It only happens when I lauched the app in debug mode, and the later hit the "stop" button though.
Crashes say 1/10 times.
4th time today... and I loose all my user preferences until last visual studio launch with every crash.
Starts to be really annoying.
This bug was targeted for a past milestone, moving to the next active non-hotfix milestone.
Looks like under certain circumstances we attempt to Delete a breakpoint twice, the second time around the breakpoint is already null.
Fixed in XamarinVS/master/258fd9d
*** Bug 17067 has been marked as a duplicate of this bug. ***
I'm having exactly the same issue described by baramuse. However, I'm using Xamarin.iOS for VS and not the Android one. The stack trace is identical and the frequency of the crashes is the same too.
It's crashed 7 times today so far... it's extremely annoying and it decreases my productivity.
I'm using version 1.10.39
Any help on the matter would be greatly appreciated.
This bug has been fixed and will be in the next release. There is currently no way to work around the issue since its intermittent.
Do you have an ETA for the next release please?
10 days to fix the bug, that's great !
3 months and still not released...that's REALLY annoying!
Still having the bug with VS2013 & Xamarin.Android 4.12.03003 (7f0e3d3c)
Are you ever going publish the fix or do you just don't want us to use Visual studio with Xamarin ?
My VS keeps crashing about 10 times per day due to this bug - this is a huge drag on productivity.
Is there any concrete plan to ever fixing it?
Same as Marcelo. This bug is a huge productivity killer. PLEASE deploy it ASAP.
I have checked this issue with XVS 3.11.666 + XI 126.96.36.199 and its working fine
at my end.
For now I am closing this issue Feel free to reopen this issue if you are
