[IronPython] Problem with Creating Executable using SharpDevelop

[Dino Viehland]

Ok, I just confirmed that mixing APTCA + SecurityTransparent + GAC works as expected so putting ourselves in the GAC should be perfectly fine to do.  There may be some additional internal process hurdles for us to jump over but we can look into that.

The big problem w/ installing into the GAC from our perspective is that assemblies in the GAC are fully trusted and can be loaded by anyone.  Combine this w/ the AllowPartiallyTrustedCallers attribute which we apply to our assemblies and you potentially have a recipe for disaster.  In theory we believe this is ok because we're also SecurityTransparent but we haven't had the deeper conversion w/ the CLR team about combining all 3 of these so we continue to be conservative and not install into the GAC.

We should probably look into removing APTCA though - the reason why we applied it in the 1.x time frame was due to a performance problem w/ signed non-APTCA assemblies which may now be fixed in the CLR.

As for actually doing the installation you now need to invoke gacutil 5 times - once for each DLL.  IronPython, IronPython.Modules, Microsoft.Scripting, Microsoft.Scripting.Core, and Microsoft.Scripting.ExtensionAttribute.  In 2.6 there'll be one more assembly to add to the list - Microsoft.Scripting.Debugging.

Installing IP into the GAC is something apparently not much discussed in polite company (e.g. AFAICT not at all in "IP in Action" or "IP URLs".)

For us .net ignorami:
* What is the downside to installing IP into the GAC? Is it that different apps will be dependent on different IP versions so better just to keep the IP DLLs together with each app?
* Is installing into GAC still done by invoking gacutil twice as described here:?

Thanks.

In general you need IronPython to be present to run IronPython apps - even
if they're compiled.  And IronPython will need to be next to the app
unless IronPython has been installed into the GAC (which we do not
do by default).  Also you probably want to include IronPython.Modules.dll
as well in addition to the DLLs you have here.  I imagine at some point
in the future we could add some sort of tree shaking compiler support
that links in IronPython w/ the app but we're a ways off from making
that a priority.

The SharpDevelop specific question I'm less sure about.
