Is it also possible to do a similar trick when you want to have a property that is a non-serializable framework class? I'd like to have a custom activity with a MailAddress property.

When I try this I get the error: CreateInstance failed for type 'System.Net.Mail.MailAddress'. No parameterless constructor defined for this object.

This is excellent stuff, however while trying to expand on this I get very stuck.

I am trying to create a custom type UI form that will receive it data from a wcf service. However no matter what I try I cannot it to work. I continually get the same error, something along the lines of 'could not find endpoint and contract'. I have tried specifing the details in code, I have tested the service in other applications and it is fine. However calling it in a WF custom type UI is not working. Any ideas on how I could this to work?

Without seeing your project there is no way for me to tell. My email address can be found through my profile at http://forums.microsoft.com/MSDN/User/Profile.aspx?UserID=43676&SiteID=1 if you want me to take a look at it.

I have followed your lead on using custom properties, and can set a value with the designer. But the value is not persisted - if I kick off the workflow containing my custom activity, the value set in the designer is missing. A value for a standard property type (string) is carried over. What might I be doing wrong?
