Add page to asp.net website if source code/project solution is not available

Question

I have been working on my clients site.

My client has only aspx and dll files now I want to add a new page to website, for testing purpose I have created a new project and uploaded its dll and aspx file but when I run the page it says.

Could not load type 'abc.index1122'

 <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="index1122.aspx.cs" Inherits="abc.index1122" %> 

Answer 1

You need to get the uncompiled solution from your client. Start with that first.

If that code is not available, you have the more difficult road of grabbing a decompiler (I recommend Telerik's JustDecompile), and then reverse engineer a solution out of the DLLs. Only then can you start making additions and recompile / deploy the code to the target machine.
