问题描述
>
1）我试图在C＃中创建一个简单的BHO，如下所示已经回答： http://stackoverflow.com/a/5740004/285594
2）但是不幸的是，他们都尝试了少于IE11，其中一些使它工作，一些失败了
你可以在IE7的Windows 7 64位上运行。下载我准备的Visual Studio 2013版本：其中包括所有的源代码和IE11的详细信息：
https://www.dropbox.com/s/60kg212vkjb7yud/ClassLibrary2.rar
Q。任何人都可以建议/建议/帮助我如何使这个BHO的一个你好世界？
我也试过其他人从codeproject中取样，但仍然没有人能够工作，从4个星期，我失去了，请告诉什么是在我的ClassLibrary2.rar中是错误的，这是不是文本浏览器？
我完全失去了，请指教。

解决方案
我试图做同样的 - 我只是注意到在构建日志中有一个错误
无法向高速缓存添加程序集：尝试安装程序集
而没有强名称
所以我添加了* .snk和突出显示工作（使用ie11到x64），但突出显示选项菜单项不起作用
1) I am trying to make a simple BHO in C# like here already answered: http://stackoverflow.com/a/5740004/285594
2) But unfortunately they all tried less then IE11, where some made it work and some failed too
3) after following everything as mentioned in that answer, i also purchased official code sign but it simply does not working in IE11 Windows 7 64-bit.
You can download my prepared version of Visual studio 2013: which includes all the source code and details for IE11:
https://www.dropbox.com/s/60kg212vkjb7yud/ClassLibrary2.rar
Q. Can anyone please advise/suggest/help how can i make one hello world of this BHO?
I have also tried others sample from codeproject, but still none of them i was able to make work yet, trying since 4 weeks, i am lost, please advise what is wrong in my ClassLibrary2.rar which is not hilighting the text "browser"?
I am completely lost, please advise.

解决方案
i'm trying to do the same - and i've just noticed that in build log there was an error
Failure adding assembly to the cache: Attempt to install an assembly without a strong name
so i've added *.snk and highlighting worked (using ie11 to, x64), but 'highlight options' menu item isn't working
