Hi, My build failed when I tried with below Version number:- [assembly: AssemblyVersion("1.0.100115... [assembly: AssemblyFileVersion("1.0.10... Here 100115 denotes the Build number in YYMMDD format. I surprised my build is failing with this build number, when I further analysed I observed anything above 65534 is considered as invalid build number in AssemblyVersion. However AssemblyFileVersion is OK with this build number. As per definition Version is Major.Minor.Build.Revision and all parts...
