c# - Razor syntax error serializing ASP.NET Model to JSON with Html.Raw

This line is giving me a syntax error in Visual Studio 2012 (literally just 'Syntax Error'):

var data = @Html.Raw(new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(Model));

Model in this case is the instance of @model MyApp.ViewModels.MyViewModel declared at the top of my cshtml.

My model is serialized properly into the data var, and the application works correctly. Cosmetically it's just annoying to have the error permanently in my error list.

How should I modify the line so that the compiler is happy?

edit:

As requested, more context. Here's the entire $(document).ready():

<script type="text/javascript">

    $(document).ready(function () {

        $('#ReportDate').datepicker();
        $('#DispositionDate').datepicker();

        var data = @Html.Raw(new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(Model));

        var vm = new NonconformingProductViewModel(data);
        ko.applyBindingsWithValidation(vm);

        // validate on page load so all reqd fields are highlighted.
        var valid = ko.validation.group(vm, {deep: true});
        valid.showAllMessages(true);

    }); // end document.ready

</script>

Using function

Implement a simple JavaScript set function that returns input argument:

function set(value){
    return value;
}

Use this function to assign Razor model value to a JavaScript variable:

var data = set(@Json.Encode(Model));

As an option you can use self-calling function:

var data = function() { return set(@Json.Encode(Model)); }();
