延迟加载实体框架错误

Question

I have created an .EDMX file from my database using Entity Framework 6.1.3. Now my code is not compiling with error:

Cannot convert lambda expression to type 'string' because it is not a delegate type.

FEED_DETAIL is not compiling as I have in MASTER_FEED class as:

public virtual ICollection<FEED_DETAIL> FEED_DETAIL { get; set; }

public MASTER_FEED GetMasterFeed(string strSnapshotId)
{
    IList<MASTER_FEED> data=_objDbContext.MASTER_FEED.Include(rw =>rw.FEED_DETAIL).Where(x => x.MAST_SNAPSHOT_RECORD_ID.Equals(strSnapshotId));

    return null;
}

Any help please.
