Hi,

I have a workflow project which was created in BlackPearl service pack 1.  The process uses a custom assembly.  The reference was added using the new Project Reference Wizard.  The project is then built and successfully completes the build.

If this workflow project is then opened on a new machine where the custom assembly doesn't exist you can not re-add the reference (to change the location) and you can not remove the reference from the Project Reference Wizard.  I also tried removing and re-adding from the extender projects but wouldn't resolve the issue.

When I tried to remove from the Project Reference Wizard, I received the following error.  "The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047).  By viewing details I got a more descriptive error ...

System.IO.FileLoadException.  The given assembly name or codevase was invalid ....

It would seem that when you remove a reference from the Project Reference Wizard, it tries to load the assembly first.  This means you cannot remove or repoint a broken reference in SP1.

Is this a reported issue or has anyone else had similar problems?

Thanks 

Dave

Have you tried to copy the missing dll to the location where studio is expecting it (probably in the same folder structure as on the previous machine) and then see if you can run the project reference wizard again?
