Using ELMAH in medium trust

Question

I'm building an ASP.net mvc app, and am having some problems getting ELMAH deployed using xml logging to a medium trust server, though it works fine on my local machine. It keeps getting a 404 error.

The problem might be that the host doesn't allow relative filepaths, so the "~/App_Data" doesn't work for logging. I switched that to:

logPath="\\Something\Something\ID\www.website.com\web\content\App_Data"

in the web.config. The syntax might be completely off, but I've tried a few variations and none of them worked.

I subsequently found this question and added the recommended code to my web.config, but still no luck. Does anyone know how to get ELMAH to work on medium trust?

Thanks!

Answer 1

The asp.net worker process (or the aspnet user) has minimum rights to write into the filesystem. Try a place like c:\temp where everybody can write files. After this check and set access rights for aspnet user.

Answer 2

It turned out that the ELMAH.dll was calling SQLite, which isn't allowed under medium trust, and was causing ELMAH to fail when deployed to medium trust. I needed to download the source code for ELMAH and re-build it without the reference to SQLite. It is now working. Yay!
