我使用 Sharpdevelop 5.1.0.5134 与 .NET 4.5.51209 基于 Windows.Forms
制作桌面应用程序首先，一切都很好，没有警告，设计师正确显示表格，我可以轻松添加组件。
之后我从软件包管理控制台中正确添加了 OxyPlot ，我在自定义组件<中找到了新的 PlotView 组件/ strong>标签。
问题是我无法从工具选项卡中将组件添加到表单中，所以我通过在源文件中编写等效语句来完成它。
构建过程很顺利，应用程序工作正常，但现在我无法在设计器选项卡中看到Form，而是收到了此消息：
Failed to load designer. Check the source code for syntax errors and check if all references are available.
ICSharpCode.FormsDesigner.FormsDesignerLoadException: System.ComponentModel.Design.Serialization.CodeDomSerializerException: Could not find type 'OxyPlot.WindowsForms.PlotView'.

我该如何解决这个问题？
答案 0 :(得分：0)
看起来SharpDevelop 5.1中的一个错误无法解析OxyPlot程序集。
看起来SharpDevelop 4.4没有相同的问题，可以在设计器中打开表单。
作为SharpDevelop 5.1的解决方法，您可以将OxyPlot.dll和OxyPlot.WindowsForms.dll文件复制到C：\ Program Files（x86）\ SharpDevelop \ 5.1 \ bin
然后重新启动SharpDevelop，然后您可以在设计器中打开表单而不会出现任何错误。
此错误应在SharpDevelop 5.1.0.5173及更高版本中修复。
