I'm using here the anonymous type because otherwise you will get a NotSupportedException: The entity or complex type 'ProjectName.File' cannot be constructed in a LINQ to Entities query.

var file = context.Files
        .Where(f => f.Id == idFile)
        .FirstOrDefault() // You need to exeucte the query if you want to reuse the type
        .Select(f => new {
            f.Id, f.MimeType, f.Size, f.FileName, f.DataType,
            f.DateModification, f.FileId
        }).FirstOrDefault();

And also its not a bad practice to de-normalize the table into further, i.e one with metadata and one with payload to avoid projection. Projection would work, the only issue is, need to edit any time a new column is added to the table.
