Here are some NAnt tasks that I wrote while working on a current
project. These are inline, and perhaps they can help others.
- getAssemblyReferences - This task returns a list of an assembly's
references as a comma-delimited string and puts them into the given
property name.
- renameDir - This task renames a directory.
- write - This task writes a string to a file without a trailing
new-line character like the <echo> task does.
- edmXtract - This task extracts the meta-data resources from a Visual
Studio EDMX file into the three SSDL, CSDL, and MSL files needed to
compile an EDM resource into a project.
Below is the XML:
<?xml version="1.0" encoding="utf-8"?>
<!--
NOTE 1
make sure to include the default namespace so that visual studio
will turn on intellisense for this nant build file
NOTE 2
for non .NET developers: for all intents and purpose a solution in
VisualStudio (VS) is the same thing as a top-level project in most other
languages, and VS project is the same as a package. in order to make it
easier for communicate amonst .NET developers working with both VS and
NAnt, this NAnt build file will refer to the top-level project as a solution
and packages as projects.
