Besides HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SDKs\Silverlight\v4.0\AssemblyFoldersEx\RedControl\Toolbox, you will also need to set HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SDKs\Silverlight\v4.0\AssemblyFoldersEx\RedControl’s default value to its install folder. As to internal classes on toolbox, it was a bug with TCI (many of the internal controls are from non TK assemblies), and should be mostly worked around in latest TK release.

Yes, this only works for VS2010. For VS2008, you have to use TCI, and it is not guaranteed to work. If you develop for Silverlight, your best option is to upgrade to VS2010.

I’m using VS2010 RTM with SL4. And I followed your suggestions in order to register my Silverlight control in Visual Studio Toolbox. It doesn’t work for me. I tried to register my control without using Toolbox Control Installer. I just added the registry key –
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SDKs\Silverlight\v4.0\AssemblyFoldersEx\RedControl\Toolbox

If you add the control to the Toolbox by creating a new Tab and then Choose Items, it works fine.

It is interesting that after installing Silverlight 4 Toolkit March 2010, the Toolkit controls weren’t registered correctly. All of their internal classes were visible.

Do you have any suggestions ?

Thanks.

Sorry for the trouble Yes, the icon issue is known, and there is no publicly documented/supported way to work around it, AFAIK. You may want to try install your controls first, and then install Silverlight SDK, or its updates, and see whether that fix your control registration issue.

We will release a new control registration mechanism, as well as fix the TCI issue, with VS2010, so hopefully this will get a lot easier.

Thanks for the clarification. Is there some other approach I could follow to achieve the same result? This is critical to my project.

I also tried the way silverlight toolkit registers its controls (putting registry entries in Microsoft SDKs/Silverlight… and using the custom action (managed toolkit actioins) to update toolbox but the issue I’m facing here is that I dont see the icons for my controls in the toolbox, instead I see a default icon for all my controls.

Any help is greatly appreciated.

It doesn’t work. As I called out, there are some issues with TCI in VS2008 that will be fixed in VS2010 (not CTP or Beta1). We are also working on simplifying toolbox registration, so stay tuned for next public release of VS2010.

Did setting registry value of SilverlightControls to 1 (instead of WPFControls) for registering silverlight controls in VS work for you? While it works for WPF, its not working for silverlight controls.
