Getting Exception when trying to upload a big files size

Question

I\'m using wshttpbinding for my service

Answer 1

The upload limit is set at 2 level, 1st by the Application and 2nd by the Server.

Your app configuration looks good to me.

Check your IIS settings as defined in your machine.config file. I found a Microsoft KB article to configure this

You can configure the value at any of these places.
