hubFS: THE place for F#

Today I switched our project to new F# 1.9.6.16 (btw. great work, especially in Silverlight support) and I have problem with build tasks for fslex and fsyacc.
Until now I used solution described in other thread on this forum, http://cs.hubfs.net/forums/thread/3655.aspx, and it worked for me.
However, when I use this approach in 1.9.6.16 I get this error:

FSharp.PowerPack.Targets(33,3): error MSB4062: The "FsLex" task could not be loaded from the assembly C:\Program Files\MSBuild\FSharp\1.0\FSharp.PowerPack.Build.Tasks.dll. Could not load file or assembly 'file:///C:\Program Files\MSBuild\FSharp\1.0\FSharp.PowerPack.Build.Tasks.dll' or one of its dependencies. The system cannot find the file specified. Confirm that the <UsingTask> declaration is correct, and that the assembly and all its dependencies are available.

I wasn't able to solve this. I'm targeting Silverlight runtime when compiling sources.

Any advice?

Looks like we maybe failed to deploy that DLL to the right directory.  Can you try copying from

c:\Program Files\FSharp-1.9.6.16\bin\gac\FSharp.PowerPack.Build.Tasks.dll

to

C:\Program Files\MSBuild\FSharp\1.0\FSharp.PowerPack.Build.Tasks.dll

and see if that fixes it?

Thanks, it works now.
I tried to copy the dll from from bin\ folder and it didn't work, I didn't expect there would be another one in bin\gac
