.netframework4.0 iso_whid 错误

在用visual studio 2010 调试时会向dbgview输出大量的如下信息：

*** HR propagated: -2147024774
[8092] ***   Source File: d:\iso_whid\x86fre\base\isolation\com

找了下有以下这些解决方案
1.在dbgview中设置过滤器
在dbgview中添加如下的excludefilters。
Workaround is to add some Exclude filters, but doesn't exclude blank lines:

*originated*;*iso_whid*;*propagated*; ;
 
2. 使用tracespy
另一个类似dbgview的项目

3. 禁用混合调试模式
This output is occuring inside the .NET runtime, and only appears when attachedwith a native debugger (usually because you are doing interop debugging). If you do not need to be doing interop debugging, disabling mixed modedebugging and enabling only managed debugging will prevent this output fromappearing.

4. 安装更新包

安装更新包：NDP40-KB2468871-v2-x64.exe
安装看了下，似乎不成

5. 没有PID的话，那么空行将不会被输出

If you can live without them , uncheck the menu item Options \ Win32 PIDs and then don't get the spurious blank lines
