>at first I thought you wanted the assembly version # at runtime. to get the assembly version at runtime I use Application.ProductVersion.

Yes, that is something I will eventually need. But, presently, from the assembly file, in the 2.5.* format, for the AssemblyVersion property, when I look at the file property from Windows Explorer, it see it ok in the assembly version. But, if I use Application.ProductVersion, will it get it from AssemblyVersion or from ProductVersion?Because, I do not see any way to specify the ProductVersion in the assembly file. So, from Windows Explorer, it always give 1.0.0.0 for that one.

>I kind of miss the auto increment version number in VFP (although it was not always fun to see how many times the assembly had been built<s>) . In .NEt if you put a * in the version number digit it uses the date time ticks (I think) to figure out what number to put in)

Ok, that would explain the 10 incrementing issue.

Thanks
