How to disable browser cache in ASP.NET core rc2?

I tried this Middleware but the browser still saving files.

I want user will always get the last version of js and css files.

public void Configure(IApplicationBuilder app)
{
    app.UseSession();
    app.UseDefaultFiles();
    app.UseStaticFiles(new StaticFileOptions
    {
        OnPrepareResponse = context =>
            context.Context.Response.Headers.Add("Cache-Control", "no-cache")
    });
}

Method 1

Disabling browser cache in ASP.NET core:

public class HomeController : Controller
{
    [ResponseCache(NoStore =true, Location =ResponseCacheLocation.None)]
    public IActionResult Index()
    {
        return View();
    }
}

Method 2

Try adding an Expires header as well:

app.UseStaticFiles(new StaticFileOptions()
{
    OnPrepareResponse = context =>
    {
        context.Context.Response.Headers.Add("Cache-Control", "no-cache, no-store");
        context.Context.Response.Headers.Add("Expires", "-1");
    }
});

Another approach would be to add a querystring that changes to the end of your requests in development. Middleware would not be required in this case.

<environment names="Development">
    <link rel="stylesheet" href="~/lib/bootstrap/dist/css/<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c3a1acacb7b0b7b1a2b3eda0b0b0fc8387a2b7a697aaaea6ed8dacb4ed97aaa0a8b0">[email protected]</a>" rel="nofollow noreferrer noopener" />
    <link rel="stylesheet" href="~/css/<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="5a29332e3f74392929651a1e3b2e3f0e33373f7414352d740e33393129">[email protected]</a>" rel="nofollow noreferrer noopener" />
</environment>

Method 3

Another way would be using an ASP-Attribute when you link your files in your _Layout.cshtml by using asp-append-version you will add a fresh hash everytime the file changed, so writing:

<script src="~/js/minime.js" asp-append-version="true"></script>

will in the end lead to:

<script src="/js/minime.js?v=Ynfdc1vuMOWZFfqTjfN34c2azo3XiIfgfE-bba1"></script>

so you get caching and the latest version out of the box.

Method 4

[ResponseCache(Location = ResponseCacheLocation.None, Duration = 0, NoStore = true)]

Try adding an annotation above the controller class.It works for me.
