[IronPython] problems to migrate from Ipy 1.1 to 2.6rc1

With any key, or your own key? The IronPython 2.6 RC1 contains signed assemblies with the key we always sign releases with, so if you just need them to be signed those are the ones I'd suggest using; you do not need to build from source. 

Feel free to read on if there is some other reason to build from sources

We all use .NET 3.5 and VS2008 SP1 on our dev machines here, so I know the project files will open; the "4.0" tools version is just a hack to make the same project files build on .NET 4.0 as well. It may complain about the version number, but it will definitely open and build. Tomas, is there anything you did to make our tools less strict about the version # (I thought not).

>>> I had to change manually the references to 'MSSharedLibdelaySigned.snk' in Src directory, is that key ok? I do not set the option 'delay sign'.

That is only a public key; you'd need your own public/private key to fully sign the assemblies yourself. Even though you are trying to fully sign them, they will be left in a delay-signed state since there is no public key. I assume you just want them signed with the key the releases are signed with, so again I suggest just using those.

>>> But then I cannot load these assemblies, i get a Strong Name validation exception

These assemblies are now delay-signed, so you need to tell .NET not to care about that and treat them as fully signed; "sn.exe" does that for you:

sn -Vr *,31bf3856ad364e35

If sn.exe is not on your path, it's located on my 32-bit machine here: C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\sn.exe. This skips-verification for ANY assembly with that public key token, so it may be a bit overkill, so feel free to specify the exact assemblies if you want.
