Answer 1

After some trials and error I found that the TextBox EditorFor view was the culprit. I documented what I found in my answer here http://forums.asp.net/t/1855963.aspx/1?Validation+messages+don+t+show+up+what+is+missing+

Basically, as long as I use this EditorFor

@*@using WebDemo.Helper*@
@model CardNumbers.Objects.PhoneInfo

<div id="PhoneInfo">
    <div class="float-left">
        @* @Html.EditorFor(model => model.Phone, EditorTemplate.TextBox)*@
        <div class="editor-label">
            @Html.LabelFor(model => model.Phone)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Phone)
            @Html.ValidationMessageFor(model => model.Phone)
        </div>
    </div>
    <div class="float-right">
        @*@Html.EditorFor(model => model.Ext, EditorTemplate.TextBox)*@
        <div class="editor-label">
            @Html.LabelFor(model => model.Ext)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Ext)
            @Html.ValidationMessageFor(model => model.Ext)
        </div>
    </div>
</div>

All seems to work OK. But if I try to switch to a shorter syntax and use this EditorFor for the textbox:

<div class="editor-label">
    @Html.Label((ViewData.ModelMetadata.DisplayName??ViewData.ModelMetadata.PropertyName),
        new Dictionary<string, object>
            {
                { "for", ViewData.ModelMetadata.PropertyName }
            })
</div>
<div class="editor-field">
    @Html.TextBox("", (object)Model,
        new Dictionary<string, object>
            {
                { "id", ViewData.ModelMetadata.PropertyName },
                { "name", ViewData.ModelMetadata.PropertyName },
                { "class", "text-box single-line"},
                { "data-bind", "value: " + ViewData.ModelMetadata.PropertyName },
            })
    @Html.ValidationMessage(ViewData.ModelMetadata.PropertyName,
        new Dictionary<string, object>
            {
                { "data-valmsg-for", ViewData.ModelMetadata.PropertyName }
            })
</div>

Validation messages do not show anymore.

Hopefully this answer will help someone or you may see what I am missing here.

I don't see a form anywhere on your page. A form context is required for validation to work. You need to wrap the Editor attributes in BeginForm block.
