从 Silverlight 4 升级到 Silverlight 5 导致 AccessViolationException [英] Upgrade From Silverlight 4 to Silverlight 5 causing AccessViolationException

问题描述

我们已将项目从 Silverlight 4 升级到 Silverlight 5，现在我们正在体验AccessViolationException 在代码的不同地方不时出现，这个异常也是导致浏览器崩溃的原因.

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.

是否有任何指导方针可以防止这种情况发生?

Is there any guideline how to prevent this from happening?

我正在添加弹出 AccessViolationException 的堆栈跟踪:

I am adding the stack trace where the AccessViolationException was popped:

推荐答案

我找到了问题的一个来源(我不确定它是否解决了所有这些 AccessViolationException 问题)，但我的系统现在更加稳定了.

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.

显然是使用最新工具包中的Bureau Black Theme，结合TextBox，导致了这个问题.

Apparently the use of Bureau Black Theme from the latest toolkit, with combination of TextBox, caused this issue.

我解决的是重新编译这个主题没有TextBox的Style，AccessViolation的问题就消失了，现阶段我们没有对整个系统做深入的测试，但这正在解决一个我可以快速重现的问题，所以我认为这可能解决了更多类似的问题.

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.

希望对某人有所帮助.
