As I pointed out in a recent post, with Microsoft’s Task Parallel Library, this is much easier. Though you still need to learn to think in terms of concurrency and the issues that arise from multiple threads accessing the same state.

Our goal is to deliver useful, high quality software to our customers. Software is not “done” until it is deployed and tested by our customers. But we encounter many problems during deployment. This post outlines common problems that lead to failure during deployment, along with common solutions.
Our work is not done until the product passes acceptance tests in the production environment or passes those tests in a target environment that is suitably like production so that we can have confidence in both the product and the process used to deploy it.
I have seen MANY projects struggle to deploy software that everyone thought was “done.” It passed tests in the development environment. But all of a sudden, it seems to be a struggle to get it to work in another environment. Here are the reasons I see and their well-known solutions. If you can offer additional advice, please post it for my benefit and the benefit of others. (more…)
