Outlook加载项中的FatalExecutionEngineerRor已从Outlook 2007迁移到2010

我正在尝试将我的Outlook 2007外接程序迁移到Outlook 2010和Visual Studio 2010。我已经完成了这些文档中描述的所有工作:

Required Changes to Run Office Projects that You Migrate to the .NET Framework 4

Updating Form Regions in Outlook Projects that You Migrate to the .NET Framework 4

Updating Ribbon Customizations in Office Projects that You Migrate to the .NET Framework 4

所有的东西都在.NET 4.0中生成,没有错误。但是当我将插件加载到Outlook(使用从vs运行)时,它会显示第一个屏幕(我的加载项在第一次运行时会显示一种启动屏幕),并在它给我之后立即显示 FatalExecutionEngineError . 因此,该外接程序在Outlook中加载良好,但在启动后不久就会崩溃。

错误消息没有提供太多细节,我不知道应该从哪里开始调试。似乎此错误不是由特定代码行引起的,因为Visual Studio无法显示其源代码。

完整错误消息:

FatalExecutionEngineError was detected
The runtime has encountered a fatal error. The address of the error was at 
0xede42270, on thread 0xc48. The error code is 0xc0000005. This error may be a

Common sources of this bug include user marshaling errors for COM-interop or 
PInvoke, which may corrupt the stack.
