<p class="MsoNormal">Hi all,<br>
I have one wish for the next release of IronPython 2.6.2 (hope it is not too late...) - please make sure it is possible to build IronPython binaries from sources. I have downloaded
<span class="apple-style-span"><span style="font-size:10.0pt;font-family:&quot;Segoe UI&quot;,&quot;sans-serif&quot;;color:#30332D"><a href="http://ironpython.codeplex.com/releases/view/36280#DownloadId=116512" id="fileDownload5">IronPython-2.6.1-Src-Net20SP1.zip</a></span></span>
 and I there is no way for me to build Silverlight binaries from it... <br>
<br>
I have opened the solution in VS 2010, solution file was converted to the new version, I selected 'Silverlight Debug' as a solution configuration and I received meny errors as below when building Microsoft.Scripting.dll:<br>
<br>
<tt><span style="font-size:10.0pt">Error&nbsp;&nbsp;&nbsp; 11&nbsp;&nbsp;&nbsp; The type 'System.SerializableAttribute' exists in both 'c:\IronPython-2.6.1\Bin\Silverlight Debug\Microsoft.Scripting.Core.dll' and 'c:\Windows\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll'&nbsp;&nbsp;&nbsp; C:\IronPython-2.6.1\Src\Runtime\Microsoft.Scripting\ArgumentTypeException.cs&nbsp;&nbsp;&nbsp;
 20&nbsp;&nbsp;&nbsp; 6&nbsp;&nbsp;&nbsp; Microsoft.Scripting</span></tt><span style="font-size:10.0pt"><br>
</span><tt><span style="font-size:10.0pt">Error&nbsp;&nbsp;&nbsp; 12&nbsp;&nbsp;&nbsp; The type or namespace name 'Serializable' could not be found (are you missing a using directive or an assembly reference?)&nbsp;&nbsp;&nbsp; C:\IronPython-2.6.1\Src\Runtime\Microsoft.Scripting\ArgumentTypeException.cs&nbsp;&nbsp;&nbsp;
 20&nbsp;&nbsp;&nbsp; 6&nbsp;&nbsp;&nbsp; Microsoft.Scripting</span></tt><span style="font-size:10.0pt"><br>
</span><br>
My goal was to build debug-able Microsoft.Scripting.Silverlight.dll because I'm receiving AddReference error which I'd like to inspect.<br>
