I've created a simple unit test project to read an app.config file. Target framework is Core 2.0. I also created a Core 2.0 console app, to sanity-check myself to make sure I wasn't doing anything weird (same test passed as expected in a .NET 4.6.1 unit test project).
The console app reads the app.config fine, but the unit test method fails and I cannot figure out why. Both are using a copy of the same app.config (not added as a link) and both have the System.Configuration.ConfigurationManager v4.4.1 NuGet package installed.
The App.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="Test1" value ="This is test 1."/>
<add key="Test2" value ="42"/>
<add key="Test3" value ="-42"/>
<add key="Test4" value="true"/>
<add key="Test5" value="false"/>
<add key="Test6" value ="101.101"/>
<add key="Test7" value ="-1.2345"/>
</appSettings>
</configuration>
The Unit Test
using Microsoft.VisualStudio.TestTools.UnitTesting;
using System.Configuration;
namespace ConfigTest
{
[TestClass]
public class UnitTest1
{
[TestMethod()]
public void ConfigTest()
{
foreach (string s in ConfigurationManager.AppSettings.AllKeys)
{
System.Console.WriteLine(s);
System.Diagnostics.Debug.WriteLine(s);
}
//AllKeys.Length is 0? Should be 7...
Assert.IsTrue(ConfigurationManager.AppSettings.AllKeys.Length == 7);
}
}
}
The Console App
using System;
using System.Configuration;
namespace ConfigTestApp
{
class Program
{
static void Main(string[] args)
{
foreach (string s in ConfigurationManager.AppSettings.AllKeys)
{
Console.WriteLine(s);
System.Diagnostics.Debug.WriteLine(s);
}
//Outputs 7 as expected
Console.WriteLine(ConfigurationManager.AppSettings.AllKeys.Length);
}
}
}
Given that I'm still pretty new to the whole .NET Core world, am I doing something totally incorrect here? I sort of just feel crazy at the moment...
