C# Interactive

REPL-like interface for C#

Opening

Open here: ctrl-e

Open using a project's context:

1. Right click on a project
2. Select "Initialize Interactive with Project"

Accessing Configs

C# Interactive runs as it's own application with its own configuration file. app.configs and web.configs do not get loaded in with the assemblies, so manually loading those is required.

There are two ways to use your configuration data with C# Interactive:

Manual Configuration

Navigate to C# Interactive's configuration file, here's the path: AppDomain.CurrentDomain.SetupInformation.ConfigurationFile

Copy over your necessary configuration elements

Change the Config with Reflection

using System.Reflection;
using System.Configuration;

public static void ChangeConfigTo(string path)
{
    AppDomain.CurrentDomain.SetData("APP_CONFIG_FILE", path);
    typeof(ConfigurationManager)
        .GetField("s_initState", BindingFlags.NonPublic |
            BindingFlags.Static)
        .SetValue(null, 0);

    typeof(ConfigurationManager)
        .GetField("s_configSystem", BindingFlags.NonPublic |
            BindingFlags.Static)
        .SetValue(null, null);

    typeof(ConfigurationManager)
        .Assembly.GetTypes()
        .Where(x => x.FullName ==
            "System.Configuration.ClientConfigPaths")
        .First()
        .GetField("s_current", BindingFlags.NonPublic |
            BindingFlags.Static)
        .SetValue(null, null);
}

ChangeConfigTo(Path.GetFullPath("app.config")); // Replace with web.config if running interactive in the context of a web application
