Have you ever had a script tag in your code like this?:

<script type="text/javascript" src="@Url.Content("~/Scripts/myJavascriptLibrary.js")" />

What’s more, did you find that it was not actually loading when the page ran?

From what I’ve found out and seen is that you can’t load a javascript file using a self-closing Script tag. You must use an open tag/close tag scenario:

<script type="text/javascript" src="@Url.Content("~/Scripts/myJavascriptLibrary.js")" >
</script>
