System.Web.Http.AcceptVerbs("GET") vs System.Web.Http.HttpGet

Question

What exactly is the difference between

    [System.Web.Http.AcceptVerbs("GET")]
    public string[] SomeArray(string someString)
    {

and

    [System.Web.Http.HttpGet]
    public string[] SomeArray(string someString)
    {

and when would one use which of them, and when would one use both? I already found many examples using

    [System.Web.Http.AcceptVerbs("GET")]
    [System.Web.Http.HttpGet]
    public string[] SomeArray(string someString)
    {

Answer 1

Both of them are same. HttpPost/HttpGet attributes are a shortcut for the HttpVerbs.Post/HttpVerbs.Get since MVC 2.0.

See this :
