Thank you for the clarifications. I did search xml files, the SDK doc, and all of the rest of the doc I could find to try to find out where Function and FunctionSet were supposed to be, and I kept finding things like FunctionAttribute and FunctionSetAttribute which had the right description, but no mention of [Function or [FunctionSet. Is there an easy way to find the mapping from e.g. Function to NAnt.Core.Attributes?
It would also be good to add your comment on the way .dlls are loaded, or a link to it, somewhere in the fundamentals section of the doc. The doc on custom tasks currently reads: "Functions can be implemented in any .NET language and are loaded in the same manner as tasks. ie either by locating your custom function assembly in the NAnt bin directory or using the <loadtasks> task."

Is this a bug? Nope, its not. 1. When starting NAnt, NAnt will load assemblies that match the following pattern (relative to the NAnt base directory) : <!-- include NAnt task assemblies --> <include name="*Tasks.dll" /> <!-- include NAnt test assemblies --> <include name="*Tests.dll" /> <!-- include framework-neutral assemblies --> <include name="tasks/*.dll" /> <!-- exclude Microsoft.NET specific task assembly --> <exclude name="NAnt.MSNetTasks.dll" /> <!-- exclude Microsoft.NET specific test assembly --> <exclude name="NAnt.MSNet.Tests.dll" /> 2. Next, some additional directory are scanned, depending on the runtime framework on which NAnt is running. In general, the following pattern applies: <!-- include assemblies specific to framework family --> <include name="tasks/<framework family>/*.dll" /> <!-- include assemblies specific to framework version --> <include name="tasks/<framework family>/<framework version>/**/*.dll" /> So, for .NET 1.0 you'd get the following pattern: <!-- include assemblies specific to framework family --> <include name="tasks/net/*.dll" /> <!-- include assemblies specific to framework version --> <include name="tasks/net/1.0/**/*.dll" /> Note: For all .NET framework versions the following additional patterns are also added to include a task assembly (and its corresponding test assembly) which is specific for Microsoft NET: <!-- include Microsoft.NET specific task assembly --> <include name="NAnt.MSNetTasks.dll" /> <!-- include Microsoft.NET specific test assembly --> <include name="NAnt.MSNet.Tests.dll" /> 3. Finally, whenever a project is loaded (started) NAnt will scan the following directories for assemblies that match the *.dll pattern: <Project Base Directory>\ <Project Base Directory>\<framework family>\ <Project Base Directory>\<framework family>\<framework version> I'd advise you to create "tasks" subdirectory in the NAnt bin directory and copy your assembly to that directory. > I'm executing the function now, so things are much better.
