c# - Details of Assembly version

Question

we will find Assembly version from Assembly.cs in every library.

[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]

My question is what is 1.0.0.0 meant by this?

Thanks

Answer 1

As stated in the file itself:

// 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")]

By changing this the following way:

// 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")]

You'll get an auto set of the last two sections (Build Number and Revision). And this auto-increment works as follows:

• Build Number: Days since 1.1.2000
• Revision: Seconds since midnight divided by two

And last but not least if you use Subversion for SourceControl you can create a template file (copy of the same file with other name) where you replace on a desired place something like this:

[assembly: AssemblyVersion("1.0.$WCREV$.0")]

And within your pre-built event of your project you'll enter something like this:

SubWCRev "$(ProjectDir)" "$(ProjectDir)PropertiesAssemblyInfo.template.cs" "$(ProjectDir)PropertiesAssemblyInfo.cs"

To get your current Subversion revision number into the version information of your application.
