Maven build error: The type or namespace name does not exist in the namespace

I build .Net project using Maven (http://maven.apache.org/). I have used .Net assembly System.DirectoryServices in the project and build pass ok. But when I add assembly System.DirectoryServices.Protocols build fails with errors:

ClassName.cs(13,32): error CS0234: The type or namespace name 'Protocols' does not exist in the namespace 'System.DirectoryServices' (are you missing an assembly reference?) ClassName.cs(684,81): error CS0246: The type or namespace name 'SearchResultEntry' could not be found (are you missing a using directive or an assembly reference?)

It looks like maven unable to resolve assembly name System.DirectoryServices.Protocols and search all classes that placed in System.DirectoryServices.Protocols in assembly System.DirectoryServices.

Assembly System.DirectoryServices.Protocols is added to project file and projects builds ok with Visual Studio, but with Maven not...

So, how I can fix above error or explain me please alghoritm of resolving .Net assemblies in Maven.
