我需要在Unity 3d中使用Microsoft Lync 2013。我已经下载了Microsoft Lync 2013的以下DLL：
在将这些dlls整合到unity项目中之后，我可以访问Lync Client和其他功能，但是unity给我以下错误：
Assembly 'Assets/Plugins/x86/Microsoft.Lync.Controls.dll' will not be loaded due to errors:
Assembly 'Assets/Plugins/x86/Microsoft.Lync.Controls.Framework.dll' will not be loaded due to errors:

我正在使用Unity 2018.3 Beta 7，它在2018.2f1或2018.2f13上均不起作用。 我现在应该怎么做才能使用这些库？
Unity项目设置：
.Net Framework 4.x
平台：独立Windows
