EF2.2

[bnemetchek2]

Entity FrameWork 2.2. Odata rather than JSON. MetaData is formatted in EF6 style.

[HttpGet]
        [Produces("text/plain")] // this will return the raw JSON without the quotes
        public IActionResult MetaData()
        {
            //var oldMeta = _contextProvider.Metadata();
            //return Ok(oldMeta);
            //dynamic parsedJson = Newtonsoft.Json.JsonConvert.DeserializeObject(oldMeta);
            //Newtonsoft.Json.JsonConvert.SerializeObject(parsedJson, Formatting.Indented);

            var metaDataString = Breeze.Persistence.EFCore.MetadataBuilder_EFC2.GetMetadataFromContext(_context);
            return Ok(metaDataString);
        }

Use EnableBreezeQuery I.e.,

[Produces("application/json")]
    [Route("breeze/[controller]/[action]")]
    //[BreezeQueryFilter]
    [EnableBreezeQuery]
    public partial class MyController : ODataController
    {
