While working on a .aspx and its code behind program, I did many changes and now it is not working as expected, and finaly lost track of the changes. Fortunately I kept a backup of it before making all those changes. Now I am trying replace (or use) its backup version and start all over again. Below are the steps I already tried.
1. Deleted the .aspx and code behind files from the folder and copied from the backup. When tried to Build the application, I got this error message.
Error 105 An error occurred when merging assemblies: ILMerge.Merge: ERROR!!: Duplicate type 'XXX_YYY_ProgName' found in assembly 'App_Web_hpbgdvnu'. aspnet_merge 1 1 ghpWork_deploy
2. Next, I copied and pasted the entire program content from the backup. When tried to Build, got the exact same error as above.
The question here is how can I make use of my backup programs?
Thank you in advance for your time and help.
