I eventually got it working. First make sure you define your xmlns in the project element...
<project xmlns="http://nant.sf.net/release/0.85-rc4/nant.xsd" ... Then you can tell studio where the schema file is by adding a catalog xml file (any name) into studios schema folder... C:\Program Files\Microsoft Visual Studio 8\Xml\Schemas for example call the file nant.xml and its content would be... <SchemaCatalog xmlns="http://schemas.microsoft.com/xsd/catalog"> <Schema href="file://C:/Program Files/NAnt/schema/nant.xsd" targetNamespace="http://nant.sf.net/release/0.85-rc4/nant.xsd"/> <Association extension="build" schema="file://C:/Program Files/NAnt/schema/nant.xsd"/> </SchemaCatalog> Paths may vary. This associates the xmlns and the build extension to the schema file. I also noticed that studio provides a schemas property for xml files which you can select schemas files from the registered schemas or ones within the solution. I couldn't get this to work properly without manually specifying the xmlns attribute though! Tony ------------------------------------------------------------------------- Take Surveys. Earn Cash.
