The AssemblyInfo.cs file generated by Visual Studio contains the following lines:

// 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")]

I was trying to auto-increment the build number by changing them like this:

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

However, when I looked at the properties dialog for my executable, the file version was "1.0.*".

This puzzled me until I came across Manfred Lange's (Manni on DotNet) very clear explanation of the difference between these attributes and how to use them effectively to auto-increment assembly version numbers. Worth a read.
