SharePoint: The final CM frontier

For a long time I thought Biztalk was the elephant in the room when it came to Configuration Management - specifically version control. I'm not talking here about Source Control, I'm talking from a deployment perspective - the 'deploy a given, atomic, integral version into production' problem.

For a traditional .net app (Winforms, ASP.Net, WPF, whatever) it's pretty much sorted. We've had source control integration in the IDE since the dawn of time, CCNet for years, and it's even easier to get CI going now that TFS 2008 supports it out of the box. That's not to say everyone actually does so, but it's there if they want it, right?

Databases are a bit harder, but there are lots of tools around that you can incorporate into your CI cycle, and now that Microsoft's in the space with VSTS for Database Pros (now included with VSTS Dev Edition) the barrier to entry has been dropped again (though it's still a pretty poor story in the SSAS space).

However for Biztalk things are not so rosy. You get source control at least, so you can practice a unified versioning / labelling scheme, but building the project doesn't give you all the artifacts you need to actually deploy into an environment. For that you've got to IDE-deploy to a dev BizTalk instance, configure and then at least export out the binding file (if not a complete MSI). There's NAnt and MSBuild tasks to do the building, but I've not seen anyone wrap up the whole end to end, so Biztalk deployments languish in the 'manual effort with concentration' department. A direct result of this is that integrating your code with biztalk orchestrations (via WS / WCF) is increasingly seen as a more manageable approach than embedding your code, thus alleviating / sidesteping many of the issues.

I thought Biztalk was the frontier of version management - that is until I started working with SharePoint.

I'd previously accepted that working with SharePoint using the Web UI was working uncontrolled, but I'd always imagined that real SharePoint developers used SharePoint Designer, checked things into source control and had established patterns for migrating content between development and production server instances. How wrong I was. Making my first tentative forays into 'how to do this properly' I was struck by the complete absence of any guidance. It appears this is most definitely not a solved problem, which Jeremy pretty much confirmed last night in his great RDN talk on the subject. There's tools out there to manage the problem, but they're pretty new on the block. The book, quite literally, hasn't been written yet.


This is clearly a pretty major failing on Microsoft's part. I appreciate that the main thrust of version-management with SharePoint is version-management of content rather than version-management of configuration, but clearly if they want developers to embrace SharePoint as a platform they're going to have to do a bit better. Time for a 'developers, developers, developers' rant perhaps?


It seems to be that the more productivity-orientated the development environment, the less effort has been put into establishing a viable CM story:



(You could substitute 'maintainability' for 'Ease of CM / CI' if you like: one tends to drive the other)


Clearly it's easier to diff / merge lines of code rather than SharePoint XML manifests (or Workflow XAMLs), but it's a complete abdication to leave these higher-level (ie non-codey) development environments quite so dramatically out the cold.

Surely there's got to be a better answer than using DiffDog for everything?

Welcome to the wonderful world of SharePoint. We all feel your pain.

Looking forward to your next post where you solve this problem for all of us :) KTHXBAI!

That's what I said to Jeremy...

I recently saw a version of this presentation from Matt Smith. He has lots of handy tricks to reduce the deployment pain.

As for actual CM, I think the recommended approach is to deploy using SP "features" and "solutions". That seems to be the official solution to the CM issue, although it then makes deployment more complex. Matt had a handy tip on how to do some stuff interactively, in the browser, and then extract what you've done out to a Feature for robust deployment/CM.

Still way more tricky than traditional non-sharepoint development tho...
