Answer 1

This page explains how to create an oDataController.

1) To install the package on your project, open the console manager and type this:

Install-Package Microsoft.AspNet.Odata

2) Open your WebApiConfig.cs and, inside Register method, add this code:

 ODataModelBuilder builder = new ODataConventionModelBuilder();
            builder.EntitySet("File");            
            config.MapODataServiceRoute(
                routeName: "ODataRoute",
                routePrefix: null,
                model: builder.GetEdmModel());

3) Create your oDataController replacing the yourDataSourceHere to use your own class:

public class FileController : ODataController
{
    [EnableQuery]
    public IQueryable Get()
    {
        return yourDataSourceHere.Get();
    }

    [EnableQuery]
    public SingleResult Get([FromODataUri] int key)
    {
        IQueryable result = yourDataSourceHere.Get().Where(p => p.Id == key);
        return SingleResult.Create(result);
    }

    public IHttpActionResult Post(FileDto File)
    {
        if (!ModelState.IsValid)
            return BadRequest(ModelState);

        yourDataSourceHere.Add(product);

        return Created(File);
    }
}

OBS: To test this solution, I changed the FileDto's property Content. More specifically, it's type! From Stream to byte[]. Posted the content as Base64 string.
