Is '@model dynamic' valid in an ASP.NET MVC3 .cshtml page?
@model Livestream.LoginModel
<!DOCTYPE html>
<html>
<head>
    <title>Remote Observation</title>
    <link type="text/css" rel="stylesheet" media="all" href="/Content/CSS/main.css" />
</head>
<body>
    @{
        dynamic dave = "Sign In";
    }
    <div class='normal center'>
        <p><img src='/Content/images/logo.png' /></p>
        @using(Html.BeginForm("Login", "Main")) {
            <div class='loginBox'>
                 <p>Username<br />@Html.TextBoxFor(m => m.Username)</p>
                 <p>Password<br />@Html.PasswordFor(m => m.Password)</p>
                 <p><input type='submit' value='@dave'></p>
            </div>
        }
    </div>
    <script>
        document.getElementById('Username').focus();
    </script>
</body>
</html>

@model dynamic

@Model.Name

@Html.TextBoxFor(m => m.Username)

@Html.TextBox("Username")
