ASP .net MVC - Master page

I am new to MVC. Where to write C# code to common functionalis开发者_运维问答ts that is comming under master page(Eg: Login)?

Create partial *.ascx view for login in shared folder and add it to master page like this:

<% Html.RenderPartial("LoginUserControl"); %>

Html.RenderAction() / Html.Action(), which do not require a Model to be passed. That is, what @x2 suggested is OK if the control is not dependent on any model, but if it is, use one of the above methods.

See: The difference between Html.Action and Html.RenderAction
