The error tells you what you need to know. Look at it again

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[MvcStudent.stu]', but this dictionary requires a model item of type 'MvcStudent.Models.StuModel'.

You are passing an object of type System.Collections.Generic.List`1[MvcStudent.stu] from your controller to your view. Your view is expecting an object of type MvcStudent.Models.StuModel.

Look again at your controller -

public ActionResult create()
{
    return View(stdb.stus.ToList());
}

Because you have not specified a view, it uses the name of the action to choose which View to try to load - so in this case: Create. Your 'Create' view contains this line at the top

@model MvcStudent.Models.StuModel

This declares you must pass an object of that Type for the view to load.

That explains the error you are getting - it seems to me like you are mixing a 'create' view with a 'list' view. Perhaps consider separating them out.
