IIS 7.5: Removing trailing slash doesn't work - trailing-slash

Question

We have ASP.NET application and set in web.config:
<rewrite>
<rules>
<rule name="RemoveTrailingSlashRule1" stopProcessing="true">
<match url="(.*)/$" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
</conditions>
<action type="Redirect" redirectType="Permanent" url="{R:1}" />
</rule>
</rules>
</rewrite>
But, the trailing slash is still there.
Also, I've tried to use the code in Global.asax.cs file:
protected void Application_BeginRequest(Object sender, EventArgs e)
{
if (HttpContext.Current.Request.Url.ToString().Contains("http://concert.local/elki/"))
{
HttpContext.Current.Response.Status = "301 Moved Permanently";
HttpContext.Current.Response.AddHeader("Location", Request.Url.ToString().Replace("http://concert.local/elki/", "http://concert.local/elki"));
}
}
But, it doesn't work as well.
The specific is "elki" is subfolder in the project and has its own web.config file that looks as following:
<configuration>
<system.webServer>
<defaultDocument>
<files>
<add value="Sections.aspx" />
</files>
</defaultDocument>
<httpRedirect enabled="true" destination="/elki" httpResponseStatus="Permanent" />
</system.webServer>
</configuration>
How to make it work, that is remove trailing slash?

<match url="^([^.]+)/$" />
