That assembly does not allow partially trusted callers组件禁止部分信任访问方

This project is exactly was I was looking as I would like to customize VLC. 本项目满足我期望。

However I am having some trouble to test it.
When I debug the demo winform, I get an error at execution time, at :当调试Winform演示程序时，运行时出错，代码位置是：

public   NLogger()
m_logImpl = NLog.LogManager.GetCurrentClassLogger();  
}

Message: 信息
An error occurred creating the configuration section handler for nlog: That assembly does not allow partially trusted callers. (C:\Users\Jo\Documents\Visual Studio 2010\Projects\nVLC\Sources\nVLC_Demo_WinForms\bin\x86\Release\nVLC_Demo_WinForms.vshost.exe.Config line 4)在为nlog创建配置节处理时遇到错误：组件禁止部分信任访问方。
If I continue to run despite this message, I get an exception at: 如果忽略此信息，产生异常：

if (m_hMediaLib == IntPtr.Zero)
{
throw new LibVlcInitException();
}

saying: 提示
Failed to initialize libVLC. Possible reasons : Some of the arguments may be incorrect. VLC dlls' version mismatch.初始化libVLC异常。可能的原因：某些参数不正确。VLC的DLL版本不匹配。

I am using dlls copied from my VLC folder. I think the version is 1.1.11.我从VCL目录下拷贝文件，我认为是1.1.11版本。

I tried to solve the first issue by adding [assembly: AllowPartiallyTrustedCallers] before the namespaces nVLC_Demo_WinForms and Implementation, but then I get this message at run time:
Inheritance security rules violated while overriding member: 'Implementation.MediaPlayerFactory.CreatePlayer()'. Security accessibility of the overriding method must match the security accessibility of the method being overriden.

Your help would be appreciated!
