Team Build integration: addin or package?

Question

Hi all,

I am writing the extension for Visual Studio (for versions 2005, 2008 and 2010) which connected with managing builds via Team Build engine.

At first, I have created the Addin but now I need to create Visual Studio Document tool windows and, as I understood, I can create such windows only inside a VS integration package.

Then I took a decision to write a package - not an addin. But I need to extend the build definition context menu (it is easy if it doing inside an addin) and now I cannot find any way to do this via CTC file (what parent group ids must be used?).

And my summary is:

I need:

1. extend build definition context menu;

2. Visual Studio document tool windows.

I can:

1. extend build definition context menu inside an Addin;

2. work with Visual Studio document tool windows inside a package.

My questions:

1. is there any way to extend build definition context menu via CTC file?

or

2. is it possible to work with Visual Studio document tool windows inside an Addin?

 

I think that it maybe possible to combine an Addin and a Package together (they can use each other). But it is preferable for me to implement the functionality either inside an Addin or a Package.

 

Thanks in advance
