iBatis Framework 4.0 Ambiguous match

[GoogleCodeExporter]

What version of the MyBatis.NET are you using?
Data Access 1.9.2
Data Mapper 1.6.2

Please describe the problem.  Unit tests are best!
If I run the project and unit test with framework 3.5, it works...but if I 
upgrade to 4.0 I get an error Ambiguous Match here
var builder = new iBatisNet.DataAccess.Configuration.DomDaoManagerBuilder();
                builder.Configure("iBatisConfig\\dao.config");

I've googled but no answer around...

Please help me!!!!
