Contact Us Email Body not changing

I have changed the body of the email generated, when a User clicks Submit button in Contact Us form.

I made the changes in Modules/ContactUs.ascx.cs as below
                    
body = string.Format("<b>From</b>: {0}<br /><b>Email</b>: {1}<br /><b>Comments</b>: {2}", Server.HtmlEncode(fullName), Server.HtmlEncode(email), body);

I also changed the email Subject as
string subject = string.Format("{0} {1}", this.SettingManager.StoreName, "Contact Us");
//Just removed the "." between the Storename and Contact Us text

But these are not getting reflected when I receive the email.

Is there any other ascx files, I need to make these changes?

I presume that you forgot to recompile the solution

Thanks for that. But for recompiling I could not find the solution file. Where can I find that?

Go here and download nopCommerce with source code.

Thanks
