Question

Now that RC1 is out I need to decide once and for all whether to use MS Ajax libraries or just jQuery for AJAX requests. The application is a new application. Essentially th

Answer 1

Well there is one thing that I found with MS Ajax framework that cannot be done elegantly with jQuery. User controls build MS Ajax are very object oriented. This cannot be easily done with jQuery. For example, lets assume you are building a "address" user control, that will have address1, address2, city, state, zipcode and country. You can build this control with jQuery and Ajax but the benefit that's provided by Ajax library is that it will compartmentalize the address control. You can define a function "reset()" on that control that would reset the contents of address control. Lets say that you want "reset()" to set address1, address2, City to Empty string but State to "AL" and Country to USA. You define the code for Ajax control in (.js) file and that function will be associated with your address control. Same is not possible with jQuery. Any function you define will be global in scope and there is no easy way to tie that function Address control. You can very well call the "reset" function on textbox control on the form!!!

So if you want to create a pure object oriented user controls then i guess better choice is using MS Ajax framework.
