How to generate WHERE EXISTS sql command

[tb-mtg]

The following code:

var users = from u in db.GetTable<AM112U>()
            from d in db.GetTable<AM114U>().Where(d => u.WINDOWSDOMAINID == d.ID)
            where d.NORMALIZEDNAME == "fakedomain"
            select u;

var query = from e in db.GetTable<AM113U>()
           where users.Where(u => e.AM_WINDOWSUSERID == u.ID).Any()
           select new { e.ID, e.HR_EMPLOYEEID, e.AM_WINDOWSUSERID };

Generates SQL:

SELECT	e.ID,	e.HR_EMPLOYEEID,	e.AM_WINDOWSUSERID
FROM	AM113U e
WHERE	(
		SELECT '.'
		FROM AM112U u
		INNER JOIN AM114U d ON u.WINDOWSDOMAINID = d.ID
		WHERE d.NORMALIZEDNAME = 'fakedomain' AND e.AM_WINDOWSUSERID = u.ID
		FETCH FIRST 1 ROWS ONLY
) IS NOT NULL

Which doesn't use WHERE EXISTS as expected and causes and error because of the FETCH FIRST 1 ROWS ONLY is unexpectedly added.

The expected SQL should be (which is what is generated when using SqlServer or Access DataProviders):

SELECT	e.ID,	e.HR_EMPLOYEEID,	e.AM_WINDOWSUSERID
FROM	AM113U e
WHERE EXISTS (
		SELECT '.'
		FROM AM112U u
		INNER JOIN AM114U d ON u.WINDOWSDOMAINID = d.ID
		WHERE d.NORMALIZEDNAME = 'fakedomain' AND e.AM_WINDOWSUSERID = u.ID
)

How can I use .Any() to produce a valid SQL statement using WHERE EXISTS?
