If you are an NHibernate’s user and you want to benefit of the Intellisense support during the editing of its configuration files in Visual Studio 2010 environment, just copy these 2 files: nhibernate-configuration.xsd and nhibernate-mapping.xsd, from the NHibernate zip into the following folder:
C:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas
where C:\Program Files (x86)\Microsoft Visual Studio 10.0 is your Visual Studio 2010 installation folder.
