I've just upodated to latest version of solutionBuildEvents (0.11.2.50249) to check if an issue I found is resolved but ...
Thing is like this - I have four projects under my solution and I've made a small program to fix version numbers. Thus I created a pre-build event with settings: Control: Enabled, Waiting for completion, MSBuild Support, SBE-Scripts support Processing mode: Files mode Files to execute: versionfix $(ProjectDir)VersionNo.h
versionfix is a small program that changes the .h file to set my desired version number. Now the issue is this - No matter which project I build, SBE always prepares and executes command for the project, which is set as 'Start-up project', and not for the one currently being built.
Should be easy to reproduce - create a solution with two projects, add a pre-build event in file mode, using the $(ProjectDir) in the path/parameters, then try to build the non-startup project and check the SBE output.
