Question

My application has been successfully updating for ages, and I’ve been making changes, releasing new builds etc every day for the past few months, but now, when the application starts (it checks for updates on startup), it begins downloading the updated version from the server, and then fails 3-quarters of the way through with the following message:

Okay, so that tells me that there is a file that was not found. But I have double-checked, several times, and the file is there.

Anybody know what causes this?

Any help at all is appreciated!

Answer 1

IIS won’t serve up *.config files by default to protect web.config and various other ASP configuration files which usually contain connection strings and other sensitive information involved in running the site. To get around this for Click-Once deployments all files get a .deploy added to the end so a *.config would be automatically renamed *.config.deploy when published. Did you manually add One Stop Management.exe.config or something? You might add a .deploy on the end as a temp workaround but in reality this should have been done for you at publish time. You DON’T want enable configs to download from IIS as this will present a security hole with your site.
