推荐答案

我在使用 System.Web 时遇到了同样的问题.我所要做的就是添加来自 GAC 的 System.Web 引用.

I had the same issue with System.Web. All I had to do was to add the System.Web reference from the GAC.

更新

GAC 在这里可能是错误的词.这些是默认的 .net(单声道)框架库.您可以在 Project/References/中找到它们，然后右键单击Edit References"，您会在 Packages 选项卡下找到框架库.

GAC is probably the wrong word here. Those are the default .net (mono) framework libraries. You can find them in Project/References/ and right click to 'Edit References' you'd find the framework libraries under Packages tab.
