Website may be up and down over next few months. I'm currently doing a complete overhaul of everything. Going back to simple individual .htm pages, new overall site theme, sanitizing and cleaning up html of all pages and blog posts, attempting to implement a new tooling and publishing system etc etc.

Provides a helper method for instantiating all types within the app domain that implement an interface

/// <summary>
/// Initializes a collection of types that implement an interface.
/// </summary>
/// <typeparam name="T">The interface type to check for.</typeparam>
/// <param name="loadingErrors">The loading errors that may have occurred.</param>
/// <returns>A list of type <see cref="T"/>.</returns>
public IEnumerable<T> GetPlugins<T>(out IEnumerable<Exception> loadingErrors)
    // search for types in each assembly that implement the type
    var fullName = typeof(T).FullName;
    var list = new List<T>();
    var errors = new List<Exception>();

    // search through all assemblies
    foreach (var asm in AppDomain.CurrentDomain.GetAssemblies())
        // search through all types
        foreach (var type in asm.GetTypes())
            // ignore abstract classes
            if (type.IsAbstract)

            // get interfaces that the type implements
            foreach (var inter in type.GetInterfaces())
                    // check if type implements interface
                    if (string.CompareOrdinal(inter.FullName, fullName) == 0)
                        // create/add type to list
                        var obj = asm.CreateInstance(type.FullName);
                        var instance = (T)obj;
                catch (Exception ex)
                    // record error

    loadingErrors = errors;
    return list;
