Assembly: MSBuild.ExtensionPack (in MSBuild.ExtensionPack.dll) Version: 188.8.131.52
Use this property to find out the largest assembly file version that was generated by the task. If only one assemblyinfo.* file was specified as an input, this will be the resulting assembly file version for that file. If more than one assemblyinfo.* file was specified, this will be the largest build number generated.
When using the MSBuild.ExtensionPack.VersionNumber.Targets file this value is placed in MaxAssemblyFileVersion property after the UpdateAssemblyInfoFiles target is run.
