AssemblyInfo.AssemblyBuildNumber Property

To change the assembly build number set this to the specific build number you want. In most cases you do not want to use this property. Instead, use the AssemblyBuildNumberType and AssemblyBuildNumberFormat properties to have this value determined automatically at build time.

To force the build number to a specific value when using the MSBuild.ExtensionPack.VersionNumber.Targets, use the AssemblyBuildNumber property, and set the AssemblyBuildNumberFormat property to DirectSet.

<AssemblyBuildNumber>0</AssemblyBuildNumber>
<AssemblyBuildNumberType>DirectSet</AssemblyBuildNumberType>
