Why does IntelliSense not offer Dispose on DataTableReader?

Question

Essentially, I have a DataTableReader object and I was reviewing my code to make sure everything disposable was indeed disposed of.

DataTableReader implements IDisposable, but IntelliSense doesn't seem to be picking up on it:

It does however work with other disposable classes, such as FileStream:

So, what gives? DataTableReader IS disposable, right?

Answer 1

It's because the DbDataReader's Dispose method has the EditorBrowsableAttribute set to Never basically telling VS to not show it. Why? I am not sure.

[EditorBrowsableAttribute(EditorBrowsableState.Never)]
public void Dispose() {
    Dispose(true);
}

protected virtual void Dispose(bool disposing) {
    if (disposing) {
        Close();
    }
}
