I'm buidling the e-commerce Website from the book "Beginning ASP.NET E-Commerce."

I got my version of the application running just find on my local Web server, but when I upload my application to my Web Hosting Service, I am getting the following error.

Server Error in '/' Application.
Method not found: System.Collections.Specialized.NameValueCollection System.Web.HttpRequest.get_Params().

Can anyone tell me what is happening here, and how to fix. Please give details because I am new at this.

Thanks.

I was getting similar error but it was HttpRequest.get_QueryString() method not found error. Make sure that ASP.NET runtime environment is same on your development box and your hosting provider. You will get this error if you developed your application using ASP.NET 1.1 (this is the case if you are using Visual Studio.NET 2003), and try to deploy this application on a box that is running ASP.NET 1.0 version.

Hope this will fix your problem.
