WF4.5 not compiling side-by-side c# workflows

Question

I have an IIS hosted xamlx workflow with c# expressions that I\'m trying to run in side-by-side versioning.

I did exactly like this article: Side by side versioning

Answer 1

After analyzing the source code from .Net, I realized that the method CreateWorkflowServiceHost that I override in my custom workflow factory, adds all supported versions in it's return object.

All I had to do is iterate this collection and compile them all.

Final source code:

    protected override WorkflowServiceHost CreateWorkflowServiceHost(WorkflowService service, Uri[] baseAddresses)
    {
        var host = base.CreateWorkflowServiceHost(service, baseAddresses);

        // add your customizations here…
        CompileExpressions(service.Body);
        foreach (var supportedVersion in host.SupportedVersions)
        {
            CompileExpressions(supportedVersion.Body);
        }

        return host;
    }
