LINQ lambda expression for many-to-one inner join involving max() - linq

Question

I have the following schema:
Table1
ID int
Table2
ID int
Table1ID int
Datetime datetime
Table3
ID int
Table2ID int
Name varchar(255)
All columns are not null. How do I write the following SQL query in LINQ using lambda expressions?
select Table1.*
from Table2
inner join (
select Table1ID, max(Datetime) as Datetime
from Table2
group by Table1ID
) a on Table2.Table1ID = a.Table1ID and Table2.Datetime = a.Datetime
inner join Table3 on Table2.ID = Table3.Table2ID
inner join Table1 on Table1.ID = Table2.Table1ID
where Name = 'me'
EDIT:
I am using LINQ to EF. I have tried
var myEntities = new MyEntities();
var a = myEntities.Table2.Select(x => new { x.Id, x.Datetime }).GroupBy(x => x.Id).Select(x => new { Id = x.Key, Datetime = x.Max(y => y.Datetime) });
var b = myEntities.Table2.Join(a.ToList(), x => new { Id = x.Table1Id, x.Datetime }, y => new { y.Id, y.Datetime }, (x, y) => x.Id);
return myEntities.Table3.Where(x => x.Name == "me" && b.Contains(x.Table2Id)).Select(x => x.Table2.Table1).ToList();
but it comes back with
System.NotSupportedException: Unable to create a constant value of type 'Anonymous type'. Only primitive types ('such as Int32, String, and Guid') are supported in this context.
highlighting the last line above. The stack trace shows it is ToList() throwing this exception.

Answer 1

I figured it out; it was that
var b = myEntities.Table2.Join(a.ToList(),
should be
var b = myEntities.Table2.Join(a,
Also, the query should be
var myEntities = new MyEntities();
var a = myEntities.Table2.Select(x => new { x.Table1Id, x.Datetime }).GroupBy(x => x.Table1Id).Select(x => new { Table1Id = x.Key, Datetime = x.Max(y => y.Datetime) });
var b = myEntities.Table2.Join(a, x => new { x.Table1Id, x.Datetime }, y => new { y.Table1Id, y.Datetime }, (x, y) => x);
return b.Join(myEntities.Table3, x => x.Id, y => y.Table2Id, (x, y) => new { x.Table1, y.Name }).Where(x => x.Name == "me").Select(x => x.Table1).ToList();
