C#

1. This is nothing to do with C#;
2. You're including both jquery.Jcrop.js and jquery.Jcrop.min.js - you only need one of those;
3. You can't use app-relative paths (~/...) in a <script> tag;

<script src="<%= ResolveUrl("~/Scripts/jquery-1.10.2.min.js") %>"></script>
<script src="<%= ResolveUrl("~/Scripts/jquery.Jcrop.min.js") %>"></script>
<link href="<%= ResolveUrl("~/Content/jquery.Jcrop.min.css") %>" rel="stylesheet" />

<script src="@Url.Content("~/Scripts/jquery-1.10.2.min.js")"></script>
<script src="@Url.Content("~/Scripts/jquery.Jcrop.min.js")"></script>
<link href="@Url.Content("~/Content/jquery.Jcrop.min.css")" rel="stylesheet" />
