Just upgraded to latest nightly build, and getting the following error:

TestCase 'NNet.Config.D4Site.CreateSite' failed: TestFixtureSetUp failed in D4Site
TestFixture failed: System.ArgumentOutOfRangeException : Specified argument was out of the range of valid values.

   at Xtensive.Storage.Domain.Build(DomainConfiguration configuration)
   at NNet.AbstractTest.FeatureSetUp() in D:\Project\NNet-Web\NNet-Test\AbstractTest.cs:line 304

I paired the code down to its bare essentials and still getting error:

Xtensive.Storage.Configuration.DomainConfiguration d4config = new Xtensive.Storage.Configuration.DomainConfiguration("mssql2005://NNetTest:NNetTest@localhost/NNetTest");
d4config.UpgradeMode = Xtensive.Storage.DomainUpgradeMode.Recreate;
//d4config.NamingConvention.NamespacePolicy = Xtensive.Storage.Configuration.NamespacePolicy.Synonymize;
// d4config.NamingConvention.NamingRules = Xtensive.Storage.Configuration.NamingRules.UnderscoreDots;
//d4config.NamingConvention.NamespaceSynonyms.Add("NNet.Model", "n");
//d4config.NamingConvention.NamespaceSynonyms.Add("NNet.Model.Config", "n.c");
d4config.Types.Register(typeof(NNet.Model.Config.Site).Assembly);
d4domain = Xtensive.Storage.Domain.Build(d4config);

I tried it with a memory configuration and it works:

            Xtensive.Storage.Configuration.DomainConfiguration d4config = new Xtensive.Storage.Configuration.DomainConfiguration("memory://localhost/DO40-Tests");
