Ja.NET - Java Development Tools for .NET

Because of my work, I need to find a way to get the fully rendered HTML of a web page build by ajax. After some googling, i found this decent headless browser which support ajax ! http://htmlunit.sourceforge.net/ but it is written in Java while the web site i am working on is build by C# , and after another search I found a tools claim to compile .java file to .net compatible .dll and after including that .dll, one can call the java class function by C# code, have anyone tried it before?
