Are they in a relation?

The question what you want. The .where statement needs a predicate. For example you can use something like this:

context.table1.Include("table2").where(a => a.value = 10));

or

context.table1.Include("table2").SelectMany(a => a.Table2.Where(b => b.value = 20));

or

context.table1.Include("table2").SelectMany(a => a.Table2.Where(b => b.value = 20), (a,b) => new
{
item1 = a,
item2 = b
}
);
