Automatically update version number

Question

I would like the version property of my application to be incremented for each build but I\'m not sure on how to enable this functionality in Visual Studio (2005/2008). I ha

Answer 1

With the "Built in" stuff, you can't, as using 1.0.* or 1.0.0.* will replace the revision and build numbers with a coded date/timestamp, which is usually also a good way.

For more info, see the Assembly Linker Documentation in the /v tag.

As for automatically incrementing numbers, use the AssemblyInfo Task:

AssemblyInfo Task

This can be configured to automatically increment the build number.

There are 2 Gotchas:

1. Each of the 4 numbers in the Version string is limited to 65535. This is a Windows Limitation and unlikely to get fixed.
   • Why are build numbers limited to 65535?
2. Using with with Subversion requires a small change:
   • Using MSBuild to generate assembly version info at build time (including SubVersion fix)

Retrieving the Version number is then quite easy:

Version v = Assembly.GetExecutingAssembly().GetName().Version;
string About = string.Format(CultureInfo.InvariantCulture, @"YourApp Version {0}.{1}.{2} (r{3})", v.Major, v.Minor, v.Build, v.Revision);

And, to clarify: In .net or at least in C#, the build is actually the THIRD number, not the fourth one as some people (for example Delphi Developers who are used to Major.Minor.Release.Build) might expect.

In .net, it's Major.Minor.Build.Revision.
