When I develop my web applications in Visual Studio 2010 I use tools such as GhostDoc, SandCastle, AJAX Toolkit, Moq, etc...
I usually use these tools in all my projects. When I downloaded the Moq tool for instance, I had a zip file with inside a couple of assemblies. Therefore, after unzipping the file, I added the relevant assemblies within the folder (in the file system) of the project I was currently developing, and then I referenced the dlls from Visual Studio.
Now the problem, or better organizational drawbacks, with this are 2:
1) I placed the assemblies within a specific project folder. That's ugly, since I would like to put the assemblies in one folder common to all the projects. Where do you usually put them?
2) Everytime I start a new project I need to reference all the assemblies over again. This, especially with the Ajax Toolkit is quite annoying. Is there any way to tell Visual Studio to add a set of predefined assemblies everytime I create a new project?
For the popular tools you can use NuGet. It will help you manage both the downloading, updating and removal of tools and referencing the appropriate assemblies.
Of the ones you mention, I found the following ones in the official NuGet packages repo:
