Assembly File Version not changing?

Question

I have in my assemblyinfo.cs class the code:

[assembly: AssemblyVersion("1.0.*")]
[assembly: AssemblyFileVersion("1.0.*")]

Calling System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString() works fine and gives the updated version, however, when i look at the generated dll in windows explorer, right click properties, click the 'details' tab, the fileversion says "1.0.0.0" even though the output above says 1.0.3489.17621 ?

You cannot use 1.0.* to auto-increment the AssemblyFileVersion, only the AssemblyVersion. (Checked in all Visual Studio versions from 2005 to 2012).

Comment out the following line

[assembly: AssemblyFileVersion("1.0.*")]

and the File Version will take the same number as the Assembly Version.

Works, im using vs2008 so it seems to have carried over. – maxp Jul 21 '09 at 11:10
Horrible situation, caught me out myself last year, fingers crossed for 2010! – Patrick McDonald Jul 21 '09 at 11:12
Unfortunately it appears they haven't changed it. I get this: warning CS1607: Assembly generation -- The version '1.0.*' specified for the 'file version' is not in the normal 'major.minor.build.revision' format – Eric Cosky Jan 26 '12 at 07:08
Seems the same way with VS 2012. – Ryan Shripat Dec 20 '12 at 17:48

Patrick already gave the correct answer, but here is just a little advice. If you look into AssemblyInfo.cs you'll find the following block at the end:

// Version information for an assembly consists of the following four values:
//
//      Major Version
//      Minor Version 
//      Build Number
//      Revision
//
// You can specify all the values or you can default the Build and Revision Numbers 
// by using the '*' as shown below:
//[assembly: AssemblyVersion("1.0.*")]
[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]

Now go on and flip the comment from the last three lines as follows:

[assembly: AssemblyVersion("1.0.*")]
//[assembly: AssemblyVersion("1.0.0.0")]
//[assembly: AssemblyFileVersion("1.0.0.0")]

And everything works as expected... :-)

Excellente, gave the answer tag to Patrick but would've given it twice if i could :D — maxp, Jul 21 '09 at 11:09
Interesting that trying to blank out the AssemblyFileVersion in the GUI doesn't let you until you comment it out like this says. Thanks! — Brock Hensley, Oct 01 '13 at 21:11
