I don't actually know how the project system worked prior to CTP3, but has
anyone tried using this construct* in the pyproj file?
<ItemGroup>
<None Include="**\*.py" />
</ItemGroup>
I vaguely recall issues in the past where VS would occasionally replace this
Include with specific file paths, but my brief experimentation with it this
morning seemed promising. Using Add->New Item to add .py files to the project
didn't affect it. The only immediate downside was files added via other means
required a project reload to show up in VS (but this could be turned into a
single button in the UI).
(*If you aren't familiar with it, this is MSBuild recursive wildcard syntax.)

Thanks Jimmy - that answers all my questions. I would *personally* prefer a
directory based solution (*much*) with include / exclude regexen but I think
our developers will be happy with a VS like solution and I can manipulate the
xml to update the project with new files.
The Chiron problem is a real problem for us and negates some of the advantage
of using Visual Studio. When there is any news on it please let us know.
Also please let me know when there is news on informing the Silverlight xaml
designer about referenced assemblies.
All the best,

Hello all,
I'm working with a team on an IronPython Silverlight application. Some of the
team develop with Windows and would like to use IronPython Tools for Visual
Studio, especially for its debugging capabilities. This means I need to create
a Visual Studio Solution and project(s) from the existing file layout.
We would like to have the project checked in under version control and I'm
aware that we'll probably need to manually manipulate the project files when we
add files outside of visual studio.
I can create the Visual Studio solution and project file and then manually
manipulate the xml to add all the folders and individual files. So far so good.
(Although perhaps not ideal having to add files individually - unfortunately I
was away during the discussion about whether projects should be able to operate
from the filesystem or have to explicitly include files.)
Yes, projects now have an explicit set of files which VS never magically
updates. Unfortunately "Show All Files" isn't supported on IronPython projects
today (well, really MPFProj<http://mpfproj.codeplex.com/> doesn't support it),
meaning there is no "add this sub-directory" option, so it's really annoying to
add a new set of files. Which means a script to update the pyproj file is your
best bet.
Dino and I were discussing a "refresh" button to enable on-demand updating, but
that kinda sucks for someone who just wants a directory browser, which is
sounds like you'd prefer? Personally I like the directory browser + regex
exclusion list, but I understand that others want a closer-to-VS experience.
Maybe there should be a toggle on the project that will put it in one or the
other modes? I say a project-setting because it wouldn't be good if a
explicit-project user created a project, and then it was opened by a
directory-browser user. =P
Next I want to be able to launch our silverlight app from within visual studio
in order to be able to debug.
The html file is in a folder call "devcode". This has a subdirectory called
"python", which becomes "python.xap" when served from chiron.
I set the startup file for the project to "devcode\index.html" and the start
directory to "devcode".
When I launch the app with debugging from Visual Studio I get the message that
Chiron has started on port 1322 and IE opens to the page
http://localhost:1322/index.html
Our html page opens (so far so good again), but unfortunately fails with the
following error:
Line: 31
Error: Unhandled Error in Silverlight 2 Application
Code: 2104
Category: InitializeError
Message: Could not download the Silverlight application. Check web server
settings
So it looks like Chiron is not building python.xap. How can I fix this?
I'm able to reproduce this too; all xap file requests are 500 errors. Must be
an issue with how VS is launching Chiron, as it works when I launch Chiron with
the same set of flags from cmd.exe. Let me poke around a bit more ...
The next problem is that the xaml designer doesn't work. It fails due to all
the external assembly references used in our xaml. Now this itself isn't so
much a problem as I know the xaml designer is ropey at the moment anyway -
however Chiron is going to have the same problem. It needs to know which
assemblies our app uses so that it can serve them (they are served externally
rather than being included in the xap file and need an entry in the Chiron
manifest.)
No need for putting an entry in the Chiron manifest; just create your own
AppManifest.xaml in the "python" directory and put your entries there. Then put
your assemblies somewhere relative to the "python" directory (like, maybe,
"bin"?), and use the same relative paths in the AppManifest.xaml, like this:
<ExternalPart Source="bin/foo.zip" />
If this is never going to work with VS tools I can move the assemblies into the
xap file as we will *probably* need this later anyway in order to allow our
application to be installed and run out of browser.
True, in SL3 ExternalParts did not work OOB, and I don't think that's changed
in SL4.
However I had assumed I could "add a reference" to the assemblies we were
using. The "add reference" dialog doesn't actually allow me to add any
references... The only active button on it is "Cancel". Is it possible to add
references to Silverlight assemblies used by our project? (And preferably have
them picked up by both the xaml designer and by chiron.)
"Add Reference" does not work in any IronPython projects, mainly because there
is no standard place to put "clr.AddReference" ... at the top of the main file?
... in a references.py file? This is more complicated in Silverlight, as it
first requires *either* that assembly to be in the XAP, or as an ExternalPart,
*or* as a zip-file script-tag, before clr.AddReference is used. So for now, the
reference must be manually added depending on how you want it deployed. In your
case, putting it in the AppManifest.xaml will work fine for Chiron, though I'm
almost certain the XAML designer will not work; we'll have to extend the
designer the same way we're doing for WPF, except with knowledge of our
Silverlight app-model.
All the best,
Michael
