&引用；“未找到项目”；及；对象引用未设置为对象的实例；在Ubuntu 16.04上使用Rider的C#项目中

我刚刚在我的Ubuntu16.04笔记本电脑上安装了和，我正在尝试构建一个项目，但我遇到了以下错误：

我见过，但对我没有帮助。欢迎任何指点。到目前为止，我还没有弄清楚为什么需要这个“AxImp.exe”。

您的项目中有COM引用。它在非Windows平台上不受支持

非常感谢您的回答。我对c#很陌生-你知道我怎样才能知道这个参考是什么吗？我们将为这个问题添加诊断。现在，您可以尝试在解决方案资源管理器中查找带有黄色警告图标的引用。谢谢。我在.cproj文件中的

Make sure the SdkToolsPath is set and the tool exists in the correct processor specific location under the SdkToolsPath and that the Microsoft Windows SDK is installed
