There are a lot of suggestions on how to resolve this issue but all of them go along the path of editing the config file.
I got my services to work in a testing program (where I can edit the file app.config) without any bigger hardship. The problem occurs when I deploy the DLLs to my customer. At their site, I can't (and I won't be able to) edit the config files.
How can I resolve this issue without accessing the config file?
