Load Unity mappings from an XML File

I would like to be able to load the following into Unity:

UnityContainer.RegisterType<ClientRegistrationVM, ClientRegistrationVMDesign>();

By loading it via an XML File.

Here would be some psudo code of what I would like to have happen.

FileStream unityMappings = new FileStream(@".\UnityMappings.xml", FileMode.Open)
UnityContainer.CreateFromXML(unityMappings);
unityMappings.Dispose();

And the UnityMappings.xml file would contain the mappings and the dlls that the types are in.

Is what I want even possible with Unity? Has anyone done this before?

You can use XML configuration with Unity, you can even mix the design time config (XML) and runtime (code) configuration.

However the Design-Time Configuration uses the UnityConfigurationSection and the config loading is only supported through this so you need to do a little more work if you want to have the config in different (e.g. not app.config or web.config) file.

Luckily you can find a sample in the documentation under: Loading the Configuration from Alternative Files section:

using System.Configuration;

var fileMap = new ExeConfigurationFileMap { ExeConfigFilename = "unity.config" };

Configuration configuration =
    ConfigurationManager.OpenMappedExeConfiguration(fileMap,                  
                                                    ConfigurationUserLevel.None);

var unitySection = (UnityConfigurationSection)configuration.GetSection("unity");

var container = new UnityContainer().LoadConfiguration(unitySection);
