Last week I reviewed some code that contains memory leaks and I noticed that they fetched some credentials from the Secure Store Service in a way that just didn't seem right to me. If you look at this code sample on MSDN you should be able to see what I mean.
I have been working on this custom workflow action
which allows you to post data to another servicer. This
can be used to send messages to a web service for
example. One thing I really wanted to have in there is
security. And with security I mean the Secure Store. It
is however very difficult to use the Secure Store from
inside a workflow action.
