Autoincrement version in Visual Studio


This is a small application with source code provided. It helps organize version auto increment in C# projects.

Using the Code


vbinc -[af1234]|[-c]|[-h]


  • a Increment assembly version
  • f Increment file version
  • 1 Increment +1.x.x.x (Increments major version)
  • 2 Increment x.+1.x.x (Increments minor version)
  • 3 Increment x.x.+1.x (Increments build)
  • 4 Increment x.x.x.+1 (Increments revision)
  • c Just show current version
  • h this help screen.


vbinc -af34

Increments assembly and file build and revision numbers.

C# has version format like [major version].[minor].[build].[revision]

  • Put vbinc.exe to the root of solution
  • Put lines
if  $(ConfigurationName) == Debug $(ProjectDir)vbinc.exe -af4
if  $(ConfigurationName) == Release $(ProjectDir)vbinc.exe -af34

or if your path contains a space character, try enclosing the $(ProjectDir) in quotes

if  $(ConfigurationName) == Debug "$(ProjectDir)"vbinc.exe -af4
if  $(ConfigurationName) == Release "$(ProjectDir)"vbinc.exe -af34

to Pre-Build event command line of each project.

From now, every Debug build will increment [revision] of assembly and file before build of project.

And every Release build will increment [build] and [revision] of assembly and file.
