: VS2012 One-Click Web Publish using file hashes instead of timestamps We have have a small ASP.NET MVC web application that we develop and publish to a remote server using Visual Studio One-Click

@Eichhorn148

Apparently there isn't a way to change it so that these settings are local to the project, but the global operation of VS can be altered.

The answer to the linked question below includes the edit to make this change to your VS.

Currently MSDeploy only uses timestamp/size/attributes to compare whether the files are different. The reason it doesn't use a hash/checksum is just for performance reasons.

So no, you can't use hashes. What you can do, on the other hand, to avoid downtime, is to either have redundant servers, or if you can't afford two servers (or running two virtual machines on a single server), at least have two websites managed by the same IIS server. You can then take offline the first website, update it, bring it back online, take offline the second one and update it.

Note: it appears from the comment of the author of the question that the source is no longer accurate. It is effectively possible to use CRC instead of the timestamp with Web Deploy. It is unclear whether Web Deploy may be customized in Visual Studio to take in account any settings one can use with MSDeploy. Web Deploy: Customizing a deployment package article seems to give some hints. See also How to: Edit Deployment Settings… and TeamCity, Subversion & Web Deploy part 3: Publishing with Web Deploy.
