Is there MicrosoftMvcAjax client library reference/documentation anywhere?

There is an good reference for their "traditional" Ajax client library here. But I cannot find any references to their MVC client library (usually contained in MicrosoftMvcAjax.js script which is included in MVC2 pro开发者_开发问答ject template). Does it exist at all?

MsAjaxMvc was only an intermediate library which currently only exists for down-level-compatibility to MVC 2.0. I would recommend you to use jQuery which is the default lib in MVC 3.0 and higher.
