[IronPython] IronPython Tools for existing project

[Michael Foord]

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.)

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?

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.)

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.

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.)

All the best,

Michael
