WIX XmlConfig

2008-07-23T19:20:00Z

Can't find good documents on WIX XmlConfig. There are some posts with examples that help me getting started:

Here is the summary of what I learned from the try-and-error approach,

VerifyPath

when setting attribute value, it has no effect
when creating element

if exists, XmlConfig does nothing - skip the action and also all the XmlConfig that reference the id;
if not, creates the element, and other XmlConfig that reference the Id;

ElementPath reference Id

Does not work when Node is 'value' - it fails saying the path can not be found.
It works when Node is 'element'

Modifying attribute:

    <util:XmlConfig Id='SetServiceCertificateFindValue'
                    On='install'
                    Action='create'
                    Sequence='100'
                    File='[WebConfigFilePath]'
                    ElementPath='[XPath_serviceCredentials]/serviceCertificate'
                    Node='value'
                    Name='findValue'
                    Value='[SERVICE_CERTIFICATE_FIND_VALUE]' />

file based workflow peristence service

WF comes with SqlWorkflowPersistenceService out of the box. But SQL is not always available, or you may just want to try your workflow program with the persistence. I implemented a file based persistence service as attached. Note it does not implement the UnlockWorkflowInstanceState which is needed only when multiple workflow runtime share the instance persistence store.

To use it, simply add the service to the runtime.

FileWorkFlowPersisetenceService fServ = new FileWorkFlowPersisetenceService(".");
workflowRuntime.AddService(fServ);

UnloadOnIdle returns true always in the implementation. So you can see that the workflow is persisted after each call when it becomes idled if you hook up the appropriate event:

workflowRuntime.WorkflowPersisted += delegate
{
Console.WriteLine("Workflow persisted");
};
