Question

We are currently reorganizing our source code, moving stuff around in a new directory structure. This impacts our Visual Studio solution and project files, where things like ass

Answer 1

In my experience, the easiest way to manipulate Visual Studio solutions using PowerShell (from within or outside of Visual Studio) is to load the project file as XML and use PowerShell to manipulate it.

$proj = [xml](get-content Path\To\MyProject.csproj)
$proj.GetElementsByTagName("PostBuildEvent") | foreach {
    $_."#text" = 'echo "Hello, World!"'
}
$proj.Save("Path\To\MyProject.csproj")

If you're running your script in the NuGet Package Manager Console, you can get the paths to all of the project files like so:

PM> get-project -all | select -expand FileName
C:\Users\Me\Documents\Visual Studio 10\Projects\MyProject\MyProject.csproj
C:\Users\Me\Documents\Visual Studio 10\Projects\MyProject\MyProjectTests.csproj
