How to pass connection string to a class library?
asp.net, c#, connection-string
Solution
The .Config that applies to libraries is the one of the executing assembly using those libraries, so you don't have to add an App.Config to your project, it will use the App or Web.Config of your startup project.
In order to get access to the `ConfigurationManager` you need to add a reference to `System.Configuration` in your library project.
Problem
I have a project structure like ``` MySolution -FrontEnd -webforms -console -Mvc -Repositories -Dapper (Class library) -Tests ``` How do I reference the connection string in my repository class library? I tried adding App.Config in my class library project but it is not available in Add New Items. I am using Visual Studio 2013 express for web. Thanks, Damien.
