Assembly Version, Assembly File Version and Assembly Informational Version
Posted in .NET on May 2nd, 2012 by Simon Dean – Be the first to comment.NET provides three assembly-level attributes for adding a version number to your .NET assembly:
[assembly: AssemblyVersionAttribute("1.0.0.0")]
[assembly: AssemblyFileVersionAttribute("1.0.0.0")]
[assembly: AssemblyInformationalVersion("1.0.0.0")]
For the last few years I’ve often left the Assembly Version set to a fixed value (e.g. 1.0.0.0) and then set the AssemblyFileVersionAttribute to the something based on a CI build number (e.g. 2.0.0.272 for build 272).
For more info on the purpose of these assembly attributes see: http://all-things-pure.blogspot.co.uk/2009/09/assembly-version-file-version-product.html
You can retrieve the value of the Assembly File Version within code. This can be useful for things like displaying a version number in your UI. Here’s the code:
var assemblyFileVersion = (AssemblyFileVersionAttribute)Assembly .GetExecutingAssembly() .GetCustomAttributes(typeof(AssemblyFileVersionAttribute), false) .Single(); return assemblyFileVersion.Version;
