TCI - Toolbox Controls Installer

TCI is a VS Package that is provided by the VS SDK as a redist. TCI allows you to easily add your custom Control to the VS Toolbox. For a brief introduction to TCI you can check the VS SDK documentation. Here I will try to cover what is happening under cover:

When you want to add your custom control to the VS toolbox using the TCI VS Package all you need is to tell TCI where the assembly containing the control is and notify to TCI this event incrementing a registry key. Probably the easier way to achieve these requirements is using a WIX-based installer (as the SDK sample does).

In order to tell TCI where your control is you can use the the fully qualified type name if you are installing the control in the GAC as following:

Or provide a location where the assembly containing the control is using the CodeBase value:

Finally you have to include the MSM containing the custom actions which notify TCI that a new Control has been installed:

The custom action will increment or decrement the "Default Items" value of the following registry entry:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\Packages\{2c298b35-07da-45f1-96a3-be55d91c8d7a}\Toolbox]
"Default Items"=dword:00000001

Note that the {2c298b35-07da-45f1-96a3-be55d91c8d7a} is the GUID for the TCI VS Package.

It's important to check if the TCI Redist is already installed before installing your custom controls if you targeting VS 2500. It's not necessary for VS codename "Orcas" because TCI Package is already installed. You can find the TCI VS Package in the VS's Private Assemblies directory.

GAX 1.3 is out!

This new version of GAX is a must if you are thinking to develop Guidance Packages using VS Codename "Orcas" (previous version of GAX didn't work with the latest version of VS) and it will also provide some new features if your are developing with VS 2005.

A welcomed “fix” is the enhancement of the registration process. Now it's smarter about whether to install VB templates based on the presence of VB as a Visual Studio's product. This means that if your Guidance Package contains VB templates (.vstemplates for VB projects or items) you won't need to add conditional logic in your installer to avoid the registration failure when the package is being installed or registered.

The GAX installer is also improved to use WIX technology but the GAT installer project that is unfolded when you create a new Guidance Package using GAT is still the same VS Setup Project.

At last, the Experimental Hive registration is now a built-in feature in GAX allowing you to register your Guidance Packages in both Normal and Experimental hives.

So it seems that this CTP is a necessary and welcomed update for the runtime but not for the UX of developing Guidance Packages.
