• nathan l Problems with state persistence and timer services

  Hi, I've experimented with adding the SQL state, timer and tracking services to the Lab1 sample step 4 (the expense report approval workflow).

If I disable the state and timer services the workflow unfolds as expected. I use the (really cool) Workflow Monitor sample to view the results, and the progress ...Show All

• Deefer SDK compatability with VS2005 RC

  First of all, the software looks great. The time and dedication is evident with the thoroughness of the design. Currently, we have our own proprietary workflow engine and were about to look at re-envisioning our designer as a DSL. With this announcement, we will have to re-evaluate our position.  We have a few guys at PDC this year and they have been very impressed with the demonstrations and labs (I just had to pick this yea ...Show All

• Jaxsurfer Using the Rules Engine with complex data containers

  We are currently working on an implementation of the WF Rules Engine to validate complex data containers. These data containers contain not only simple properties, but collections of other data containers which themselves may also contain collections of other containers.

At some point in code where the workflow gets persisted the workflow terminates himself, because certain objects I use are not [Serializable]. I assume, that the Runtime tries to persist the workflow. The contained parameters in the workflow are not all [Serializable] and therefore cannot persist the workflow. Then it terminates itself. My question: Has anyone e ...Show All
