hubFS: THE place for F#

Hi there. I am trying to compile an F# module to target Silverlight 2b1 and have hit a brick wall. The F# file "hello.fs" contains no code, and I get the following error,
   

Implicitly referencing 'C:\Program Files (x86)\Microsoft Silverlight\2.0.30226.2\System.dll'...

Typecheck implementation Hello

Note, optimizations are off.

FS0193: internal error: the module 'System.Net' from compilation unit 'System' did not contain the module/namespace 'Net'

FS0193: Not_found

The command line is

fsc.exe  --fullpaths --progress -a -Ooff -g -o "hello.dll" --no-framework --clr-root "C:\Program Files (x86)\Microsoft Silverlight\2.0.30226.2" --no-mllib "hello.fs"

Note that System.dll is referenced, even though the --no-framework option is specified. I have tried also referencing System.Net but to no avail.

Any help appreciated.

Thanks,
Andrew.

Some digging with ildasm reveals a reference to System.Net.WebResponse in FSharp.Core.dll, which in .NET is defined in System.dll but in Silverlight is defined in System.Net.dll. Could this be the problem? If so, can anyone suggest a workaround?  Merely adding -r System.Net.dll to the command line does not work.

You need to recompile FSharp.Core.dll against the Silverlight framework assemblies. A moderately annoying task since fslib somtimes references method overloads that are not in Silverlight.

Anyway I have done the recompile and it seems to work. With permission from Microsoft I'll post the binary here or contact me privately.

I got the same error
Is there any other solution?

I reverted to version 1.9.2.9, which works. The problem with recompiling the sources is that the licence terms do not permit redistribution, which rather defeats the object of Silverlight.

I reported the issue to Don Syme who kindly passed on a bug report.

Amdrew.

In the 1.9.4.19 minor update we removed a method that depends on System.Net. Please let us know if that improves things here (we believe it should)

thanks

I would be very interested in getting the Silverlight-Compiled Core-Dll. I have been working on a small component for a silverlight application prototype and would like to test that without having to rewrite it in C#. I will have to do that anywayeventually , but I'd just like to postpone that as much as possible.

cheers
