Slow showing / drawing dialogue with ListBox?

Question

My application uses entity framework to pull in a small tiny set of results... It takes about 3 seconds for it to do it? Why might this be?

Start.cs

Answer 1

Changing my IEnumerable to IList made a difference:

public static class PreLoadedResources
{
    public static IEnumerable projectTypes;
}

to

public static class PreLoadedResources
{
    public static IList projectTypes;
}

then in my loading (which takes a 2 second hit), I just .ToList it instead... but now the showdialogue procedure takes split seconds.
