DevExpress Troubleshooting - 控件重复加入Visual Studio 2010的ToolBox

似乎是DevExpress的Bug,每隔一段时间，每当打开Visual Studio 2010时，DevExpress 12.1的控件就被重复加到ToolBox一次。在DevExpress意识到这是他们的一个Bug并给出简单的结局方案之前，只能按照DevExpress Support提供的以下方法来修复：

 

The following steps allow you to reset the Toolbox completely and enable Visual Studio to rebuilt it from scratch. In most cases, this procedure solves all issues related to Silverlight toolbox items.

 

Above all, reset the Toolbox from Visual Studio. For this right-click the Toolbox and click the "Reset Toolbox" item. After the reset procedure is done, follow these steps:

1. Close Visual Studio;

2. Open the "c:\Users\<your_user_name_here>\AppData\Local\Microsoft\VisualStudio\10.0" (Windows 7) folder and remove all the .TBD files;

3. Run the "regedit" tool. For this click the "Run" item in the Start menu and type "regedit" without quotation marks;

4. Find the "HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\ToolboxControlsInstaller_AssemblyFoldersExCache" and"HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\ToolboxControlsInstallerCache" keys;

5. Remove everything from these keys leaving them empty;

6. Run Visual Studio again and wait until it recreates all items in the Toolbox.
