asp.net mvc - MVC <form action=@Href -

i'm doing tutorial https://www.youtube.com/watch?v=wwmuftweh6y , i'm having problem understanding why @hrefdoesn't work.

@href i'm asiming should pointing update actionresult in postscontroller, doesn't work, , don't see problem. have postscontroller u can see in picture, , have public actionresult update in postscontroller. why path not found?

i have no hair left end of tutorial!

edit: in picture underlined 2 things, kinda figured out other one.

update:

   public class postscontroller : controller {     //update takes (id, title, body, datetime, tags) public actionresult update(int? id, string title, string body, datetime datetime, string tags) { ....... } 

you should use @url.action("update", "posts"), it's more easy use. full list of overloaded methods here , pick 1 fits needs.

as alternative forms, use @html.beginform(). example of usage here:

@using (html.beginform()) {     @html.textbox("name");     @html.password("password");     <input type="submit" value="sign in"> }
