Question

当我在我的项目中添加一个新的Telerik表单时，我得到一个错误。

运行向导时出错。

在该路径上创建"ControlScenarios“目录后，在添加Telerik表单时出现以下错误。

此错误是一个已知问题，与跨多个Telerik扩展的共享资源相关。在您的案例中，最有可能的是用于WinForms扩展的Progress Telerik UI和Progress Telerik WinForms转换器。要解决此问题，您可以从Extensions -> Manage Extensions ->安装的Extensions中禁用或删除Telerik WinForms转换器扩展。
