问题
What and how should I put into an app.config file.
The scenario is this, I have created a C# Windows Forms application (.NET 4.0), and it runs fine on the development computer. When I deploy it using ClickOnce on other computers I get a permission error for the machine.config file. This is a corporate domain so I do not have rights to change the permissions in the machine.config file on the target computers. From what I have been reading, I believe that whatever is being accessed in the machine.config file can alternately be placed into the app.config file. The problem is I do understand what would need to be placed into the app.config file, and I do not understand some of the aspects of the configuration such as 'keys', etc.
How can I avoid the use of the machine.config file altogether, and what exactly needs to be configured to do so?
