silverlight - 从 Silverlight 4 升级到 Silverlight 5 导致 AccessViolationException

Question

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

是否有任何指导方针可以防止这种情况发生？

我正在添加堆栈跟踪，其中 AccessViolationException被弹出:

Answer 1

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)，但是我的系统现在更加稳定了。

显然是使用 来自最新工具包的 Bureau Black Theme , 与 的组合文本框 ，导致这个问题。

我为解决它所做的是在没有 TextBox 样式的情况下重新编译此主题 并且 AccessViolation 的问题已经消失，在这个阶段我们没有对整个系统进行深入测试，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。

希望它对某人有所帮助。

问候，
