推荐答案

成功构建后，当前项目中的用户控件将自动添加到工具箱中，而您无需执行其他任务即可.

User controls which are in the current project will be added to toolbox automatically after a successful build and you don't need to perform additional tasks to do so.

工具箱中未填充新用户控件的此类问题通常是生成错误或设计者错误.要解决该问题，您可以执行以下任务:

Such problems which the toolbox not being populated with new user controls, are usually build error or designer errors. To solve the problem you can perform these tasks:

• 关闭Visual Studio

• 删除Visual Studio设计器中的缓存文件.为此，请转到以下路径并删除所有文件夹:

• Close Visual studio

• Delete Visual Studio designer cached files. To do so, go to below path and delete all folders:

%userprofile%\appdata\local\Microsoft\VisualStudio\11.0\Proj‌​ectAssemblies 

删除项目的 bin 和 obj 文件夹.
