ASP.NET Web Application (MVC) Deployment Automation and Subversion
We are trying to automate the build process to our staging servers but have run into a snag, albeit fairly minor. We are using the Publish functionality built into VS2010, committing to Subversion, and then a 3rd party app (Beanstalk) automatically pulls the updated files and FTPs them to the Staging server.
The problem we've run into is that we only appear to have the following choices:
My question: Is there an easy work around for this, or a totally different deployment option we're overlooking (we do not want to publish directly to the server from VS, as we want to track who/what/when a deployment takes place)? The only thing I've come across is to delete the file contents manually prior to publishing, while leaving the folder structure intact, then deploying with "Replace matching files with local copies". Unfortunately, this brings on a whole new meaning of the word "automation".
Any ideas on how best to accomplish this?
You may want to consider using NAnt or something similar for tasks you wish to automate, like building and publishing to Subversion. This is most of my build file for a WebApplication Project. It might be different for MVC. If so, I'm sure you can use this as a starting point. I am by no means an NAnt expert so there may be some flaws, but this is definitely working for me.
I had to add a PublishToFileSystem target to each .csproj file I wanted to publish. The source for that can be found here.

We also deploy out of SVN and ran into the same problem. Our solution is to essentially branch the project for "significant" upgrades -- situations where we were adding and deleting files, not just fixing small bugs and making tweaks which you can usually handle by xcopy. Svn layout looks like:
--project
---production
----20100101
----20100213
[etc, etc]
Procedure-wise, it is pretty simple -- if there are big enough changes, check in build artifacts as appropriate.
Another thing you might want to try, especially if you cannot get your production bits to "switch" branches easily, would be to use something fancier such as powershell to execute the delete files command, that could filter out the *.svn folders.
I would say "fortunately" this brings a whole new meaning to the word automation :) What you're describing is knows as Application Release Automation, also sometimes called Deployment Automation. If you really want to know who did what and where, what was the outcome, etc. then you are looking for a product like Nolio ASAP (http://www.noliosoft.com). Please let me know if this helps, since from what you're describing, it seems like a perfect match.
