Upgrade From Silverlight 4 to Silverlight 5 causing AccessViolationException?

I have found one source of the issue (I am not sure that it solved all these AccessViolationException issues), but my system is much more stable now.

We have upgraded our project from Silverlight 4 to Silverlight 5 and now we are experiencing AccessViolationException from time to time in different places in the code, this exception is also causing the browser to crash. Is there any guideline how to prevent this from happening? I am adding the stack trace where the AccessViolationException was popped: Managed to Native Transition System.Windows.

1 Not a real answer, so I'm putting this in the comments. But it seems you're not alone: stackoverflow.com/questions/8495242/…, forums.silverlight.net/t/245247.aspx/1, ... – Peter Jan 5 at 14:48 I'm still fighting with this one. Are you able reproduce this?

I'm not able to make this happen outside of my project. – Aligned Jan 5 at 19:13 Are you using Telerik's controls? They have fixed one occurrence of this (I've been following some links, copying this info here).

– jv42 Jan 6 at 14:40 I am not using telerik controls, didn't tried to create a test project, – liorklain Jan 8 at 7:35 @jv42: Have Telerik provided any info about the fix, what it required, or even the cause of this behavior? – MichaelS Jan 8 at 20:02.

I have found one source of the issue (I am not sure that it solved all these AccessViolationException issues), but my system is much more stable now. Apparently the use of Bureau Black Theme from the latest toolkit, with combination of TextBox, caused this issue. What I have done to solve it is to recompile this theme without the Style of the TextBox and the issue of AccessViolation has disappeared, at this stage we didn't do deep testing on the entire system, but this is solving an issue that I could repro rapidly so I assume that this might have fixed more issues like that.

Hope it helped someone. Regards, Lior.

Ok, I've found a solution. Previously I had the overall app styles/theme set in the Mainpage. Xaml file - and the theme rippled down to all child navigation pages at runtime.

This was causing the problem somehow. If I explictly set the style on a page by page basis - everything works! Thus: (using the BureauBlue toolkit theme) xmlns:SystemColors="clr-namespace:System.Windows.Controls.

Theming; assembly=System.Windows.Controls.Theming. BureauBlue" .

My guess is it is either a faulty runtime installation, or browser add-on or antivirus. Troubleshoot it this way: What does DrWatson logs show? Tess Ferrandez has a lot of information on how to read crash logs.

Or post your crash log here. Does it happen with different browsers? Can you turn off any Add-Ons?

Does it happen on all computers? Does your app use any COM automation or PInvoke?

2 This error reaccour on different computers (more than 2) and on different browsers. – liorklain Jan 11 at 11:23 Please post your crash log. – Chui Tey Jan 11 at 20:22 I have also attached screen shot to the qustion, but this is what I get as exception.

System. AccessViolationException was unhandled Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

InnerException: – liorklain Jan 15 at 15:43 Have a look at this ContentManagerSilverlight! ContentManagerSilverlight. TextPropertyPanel.

Set_ItemDe? Tails Perhaps it is cross-thread access. – Chui Tey Jan 15 at 22:43 No, it is happenning from the Main thread of the application (i have doubled checked it from my Visual Studio) – liorklain Jan 16 at 10:07.

We have the same thing happening on a TextBox_GotFocus() event, where I perform a ((TextBox)sender).SelectAll(); call. The code is fine in the Silverlight 4 runtime, but executing it on a PC with Silverlight 5 installed crashes out the browser. We have tried this on several different machines with the same result - getting users to downgrade back to the 4.

X runtime fixes it everytime. This is obviously a bug on Microsofts side - no matter what, it should never result in the browser crashing!. However we need this code to run in Silverlight 4 first and foremost - so any fix has to work in that version too.

We are using the Bureau Blue style in this app. Will try it without the styles, but it still doesn't explain why its failing?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
