Increment Build Number in VS.NET

Little quick and dirty program (60 lines) which updates the version build number each time a release is built.

Introduction

In VS 6, we had an autoincrement of the build number, if we build a new *.exe file. In VS.NET, I miss this feature. Here I submit a quick and dirty program (60 lines) which updates the version line in AssemblyInfo.cs each time a Release version is build.

Basics

Beau Scinner has written a lot about the basics, but it works only in VS 6. In VS.NET is AssemblyInfo.cs file, which contains the information of the Application.ProductVersion in the form of one line:

// 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 Revision and Build Numbers 
// by using the '*' as shown below:

[assembly: AssemblyVersion("1.0.13")]

IncBuildNo reads this file, increments the last number by 1 and writes it back.

Calling IncBuildNo

IncBuildNo's 1st arg is the path and filename to AssemblyInfo.cs.
Optional it reads a 2nd arg Release. If the 2nd arg is given, but if arg!="Release", IncBuildNo returns without any action, I add this option, that IncBuildNo is able to select the VS.NET environment Release/Debug.
If you omit this 2nd arg or the 2nd arg is Release IncBuildNo increments the last number of the version string (otherwise it skips incrementing).

In the new version, I add some error-output to the Application Event Log.

Installation

If you download the project above, you have a complete installed example.

In your own projects, take the following steps:

  1. Copy IncBuildNo into the same directory as AssemblyInfo.cs (normally the $(ProductDir))
  2. In VS.NET, select Project -> Properties -> Build Events
  3. Insert in Post-build Event CommandLine:
    "$(ProjectDir)IncBuildNo" "$(ProjectDir)AssemblyInfo.cs" $(ConfigurationName)
  4. Select in Run the Post-Build Event? When build updates the project output

Now each time you build a new release, the last number of the version is incremented.

1st Note: After a successful build of a release, AssemblyInfo.cs shows the version of the release +1.

2nd Note: If you use a installation-project when you build your application, you can insert a line in the postbuild event property in the project properties of this installation project. I use e.g.

"$(ProjectDir)IncBuildNo" "$(ProjectDir)..\AssemblyInfo.cs" $(ConfigurationName) 

Attention: In this case, the $(ProjectDir) points to the install project, not to the application project. This is the reason for the ..\ phrase in the above line. But then the increment happened only if the building process is running, i.e., you can build a Release-Version without incrementing the build number.

I hope this will help you.

My first approach to computers was in 1970 a IBM1160, a real desk computer, this means it was as large as a desk and had a cartreader and 32 kByte Memory! But it runs FORTRAN! Ok 'run' is a little too fast

Later I was very proud on my Comodore CBM8032 32KbRAM+32KbRom (uff!) and 2 (in words 'TWO') floppies. But it was able to run a Basic-Interpreter. (There was a young gay in USA, who invent and developed the garbage collecter for such interpreter, his name was Bill G.)

Unfortunatly this CBM8032 burned away due to some "experiements"...

Ok, later I studied physics and work now since 20 years in the cancer research in Switzerland. My own little company Ariadne-Consulting delivers the login name:
