I compiled NHibernate with VS2005 and ran the tests in NHibernate.Test against a SQL2005 database. Test FooBarTest failed on the following assertion at line 2114 in FooBarTest.cs

Assert.IsTrue( NHibernateUtil.IsInitialized( f.TheFoo ) );

The test works fine under VS2003. Comparing SQL Profiler traces from VS2003 and VS2005 shows more SELECT's using VS2003 generated by the statement preceding the assertion

list = s.CreateCriteria( typeof( Foo ) )
.Add( Expression.Expression.Eq( "Integer", f.Integer ) )
. Add( Expression.Expression.Like( "String", f.String ) )
.Add( Expression.Expression.In( "Boolean", new bool[ ] {f.Boolean, f.Boolean} ) )
.Add( Expression.Expression.IsNotNull( "TheFoo" ) )
.SetFetchMode( "TheFoo", FetchMode.Eager )
.SetFetchMode( "Baz", FetchMode.Lazy )
.SetFetchMode( "Component.Glarch", FetchMode.Lazy )
.SetFetchMode( "TheFoo.Baz", FetchMode.Lazy )
.SetFetchMode( "TheFoo.Component.Glarch", FetchMode.Lazy )
.List();

Has anyone else seen this problem?

EDIT - More Info: Here's the log output from the two tests (VS2003 and VS2005).
