    As a workaround in the meantime, you could create global "enums" from your metadata like this:

    .then(function (data) {

    // extract all enums als global objects
    ko.utils.arrayForEach(data.schema.enumType, function (c) {
    window[] = {};
    ko.utils.arrayForEach(c.member, function (m) {
    window[][] = m.value;


    So if you had an enum called "Status", you would now have a global object that you can call:

    var currentStatus = Status.Done; //returns the value as defined in the server side enum

    Yeah, pls, at least show us an example of how to bind the enums to a knockout select dropdown

    Yes please expose these. As stated above you are passing these to the client but we can't access them in the breeze api. I would give this 10 votes if i had it

    This is so trivial, you're actually have it in the metadata.
    Don't understand why they haven't epxosed it in the first place.

    From what I can see this is just a matter of exposing the data in the api? looking at the metadata it includes the definitions for the enums. There just isn't a way to actually get that data out of the metadata store. Looking at the relevant property of my type, it's enumType property has the value Edm.Self.EnumType but it's just a string and no where else can you actually just get those values.
    Correct me if I'm wrong?
