I want to include the current time and date in a .net application so I can include it in the start up log to show the user what version they have. Is it possible to retrieve
You could update the Assembly version in AssemblyInfo.cs as part of your build. Then you could do something like this
FileVersionInfo lvar = FileVersionInfo.GetVersionInfo(FileName);
FileVersionInfo has the information (build/version,etc) that you looking for. See if this works out for you.
