  InnerException: 

解决方案：

将App.Config里面有一段，对Runtime的设置

原：

   <startup >
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />

    </startup>

修改为：

        <startup useLegacyV2RuntimeActivationPolicy="true">

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />
</startup>
