Reading settings from app.config in .net 4.5

Question

I've added a reference to System.Configuration. I've created App1.config in my project and populated it with the following code:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
 <appSettings>
  <add key="ResistanceA" value="0.04"/>
  <add key="ResistanceB" value="0.04"/>
  <add key="ResistanceC" value="0.01"/>
  <add key="TempBattLow" value="40"/>
  <add key="TempBattHigh" value="45"/>
  <add key="TempLoad" value="40"/>    
 </appSettings>
</configuration>

Then I try to read the values using the following code,

using System.Configuration;

string str = ConfigurationManager.AppSettings.Get("ResistanceA");

However I do not get the data. Any idea what I am doing wrong? Thanks.

Make sure the (app name here).config file actually appears in the same folder as your (app name here).exe file. Being that you called it App1.config, I'm guessing that you have more than one.

Visual Studio renames App.Config to the actual (app name here).config file during a build, not App1.config.
