如何在 Web Publish 发布包中包含类库的 App.Config 文件

Question

I have ran into a scenario where I have added an App.Config file in a Class Library which I am referencing from my ASP.NET MVC project .

Now while publishing my Web project I can only see the DLL of the class library in the Bin folder but not the App.Config of the same. Is there any way to include that in the Web publish.

Thanks

Answer 1

You need to tell the compiler to copy these files to the output directory. To do so, select the app.config from the solution explorer and hit F4 for properties and select Copy Always like the below example

Answer 2

Your class library shouldnt be using the app.config file. Instead the driver application or consuming application should be having a single app.config and should feed this dll with parameters.

This will also help your application being more SOLID. Your class library should be doing single job. Reading from a app.config file adds a second responsibility.

Also, class library not reading from the app.config file make your class library loosely coupled and it can be taken anywhere.
