is possible that syntax rule is shown as error because of the VS 2008 support and not the language version? We arent using IronPython 1.x in any computer unless it's a mistake, Im not there now but I dont remember any asp.net sample folder which came with version 1.x<div><br></div><div><div><div><br></div><div><hr id="stopSpelling">From: dinov@microsoft.com<br>To: users@lists.ironpython.com<br>Date: Sat, 20 Nov 2010 19:32:31 +0000<br>Subject: Re: [IronPython] IronPython source code<br><br>

<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:'Calibri','sans-serif';color:#1F497D">Wow, you must still be using IronPython 1.1 or IronPython 1.0. The conditional expression was added in Python 2.5 so it’s in IronPython 2.0 (which maps to
Python 2.5). I’m guessing the VS 2008 support you’re using is IronPythonStudio which I believe is still at 1.0/1.1 as well.</span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:'Calibri','sans-serif';color:#1F497D"> </span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:'Calibri','sans-serif';color:#1F497D">We did release the code for the ASP.Net integration (see Jimmy’s announcement here http://blog.jimmy.schementi.com/2010/07/aspnet-dynamic-language-support-is-open.html)
but I don’t remember if we included / re-built it for the 2.7B1 release. The reason I bring this up is I think the best possible upgrade path if you want both ASP.NET + VS support would be to move to IronPython 2.7 and VS 2010. If that’s not too big of a
jump for you I think you’d find it’s a much better experience than 1.1 and the VS 2008 integration which is a little lacking in some aspects.</span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:'Calibri','sans-serif';color:#1F497D"> </span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:'Calibri','sans-serif';color:#1F497D">But if the conditional expression was the one extra thing you wanted you could also consider back porting it to IronPython 1.1 – it shouldn’t be very difficult.
The parser side of things won’t be much different between 1.1 and 2.7 but the code gen side will require some IL generation which will also give it more of a traditional compiler feel. 1.1 is also a little simpler in some aspects so it might be easier to
get a feel of things there and then when you look at 2.x you can see how the DLR has been added in on top of that.</span></p>

code now (we generally just generate expression trees everywhere). So if you’re interested purely in the compiler side of things you can look at the Tokenizer->Parser->AST transformations but then we’re basically done w/ code gen at that point.</span><span style="font-size:10.0pt;font-family:'Tahoma','sans-serif'"></span></p>

From there you can "upgrade" to IronPython, but then hopefully you'll feel comfortable with just the source code. There are some old docs at <a href="http://ironpython.codeplex.com/wikipage?title=More Information" target="_blank">http://ironpython.codeplex.com/wikipage?title=More%20Information</a>,
