Microsoft Ajax script extensions - same in both ASP.NET AJAX and ASP.NET MVC?

Question

Are the client side javascript extensions, e.g. MicrosoftAjax.js, the same in both ASP.NET AJAX (for ASP.NET WebForms) and ASP.NET MVC?

For example, does it still include:

• Global Namespace
• Sys Namespace
• Sys.Net Namespace
• Sys.Serialization Namespace
• Sys.Services Namespace
• Sys.UI Namespace
• Sys.WebForms Namespace

although I'd suspect that the Sys.WebForms namespace might be redundant for MVC...

Answer 1

Both frameworks share the same MicrosoftAjax.js file, but each has a seperate additional ajax file too:

MVC has a MicrosoftMvcAjax.js file Webforms has a MicrosoftAjaxWebForms.js file.
