'jquery' is not a valid script name. The name must end in '.js'

Question

My ASP.Net project is working well, when suddenly we had a power failure. When I ran my web app, it is now showing a lot of

Could not load assembly S

I had a similar situation, but mine happened after I tried to update DotNetOpenAuth.Core. First it said I needed to update NuGet, which I did, then I updated OpenAuth. After that I started getting the "'jquery' is not a valid script name. The name must end in '.js'.".

If I removed the line adding the jquery bundle, it would happen on jquery-ui etc.

I uninstalled and reinstalled both the AspNet.ScriptManager.jQuery and AspNet.ScriptManager.Bootstrap packages (as it would eventually complain about that), and still no luck.

Final step I did was to uninstall and reinstall AjaxControlToolkit from the package manager console and that fixed it for me.

I had a similar situation and already had the script reference (above) but I also needed to make sure that the dll was copied to the local folder.

F4 on AspNet.ScriptManager.jQuery and AspNet.ScriptManager.jQuery.UI.Combined and set Copy Local to True.

may be a little late to the party but I had the same problem and tried numerous solutions as per above and on other pages. I would get the error on the last script reference, no matter what that reference was. I finally decided to remove all the script references and use bundles instead. For example, default application has the following in bundles.config:

bundles.Add(new ScriptBundle("~/bundles/MsAjaxJs").Include(
    "~/Scripts/WebForms/MsAjax/MicrosoftAjax.js",

ScriptManager.ScriptResourceMapping.AddDefinition(
    "respond",
    new ScriptResourceDefinition
    {
        Path = "~/Scripts/respond.min.js",
        DebugPath = "~/Scripts/respond.js",
    }
);

So I changed 'respond' to a bundle instead of a script reference:

bundles.Add(new ScriptBundle("~/bundles/respond").Include(
    "~/Scripts/respond-1.4.2.js"));

along with all other script references, and added them to the master page header:

<asp:PlaceHolder runat="server">
    <%: Scripts.Render("~/bundles/WebFormsJs") %>
    <%: Scripts.Render("~/bundles/MsAjaxJs") %>
    <%: Scripts.Render("~/bundles/jquery") %>
    <%: Scripts.Render("~/bundles/jqueryui") %>
    <%: Scripts.Render("~/bundles/modernizr") %>
    <%: Scripts.Render("~/bundles/respond") %>
</asp:PlaceHolder>

This removed the error - finally after 2 days - and allowed me to run some basic pages, including the default Register.aspx page. Not sure what I'll run into next but figured I would pass this along.

This fixed my issue. Add this BundleConfig.cs Check your paths.

 ScriptManager.ScriptResourceMapping.AddDefinition("bootstrap", new ScriptResourceDefinition {
                Path = "~/scripts/bootstrap.min.js",
                DebugPath = "~/scripts/bootstrap.js",
                LoadSuccessExpression = "bootstrap"});

And kept this in the ScriptManager on the site.master

  <asp:ScriptReference Name="bootstrap" />
