c# - Possible to remove and add a reference to csproj programmatically via a batch file?

Question

I am writing a short batch file to prepare a control library DLL with Examples project for deployment via sip file and have the following question.

Given a csproj file at known location and a DLL at known location, is it possible to programmatically update the csproj from the batch file (via third party command line exe, or other scripting) to add the new DLL?

My folder structure is

/Build 
   /SDK
      /WPF
          /4.0 : ControlLibrary.dll sits here
   /Examples
      /WPF
          /4.0 : Examples.csproj sits here

Assuming the batch file is at the /Build level, is there any way to modify Examples.csproj to reference ControlLibrary.dll ?

Just to clarify, the reason why I have the structure like this is I wish to deploy an examples csproj to ship with my control library. Examples.csproj should reference the obfuscated control library under SDK/. Examples.csproj also exists on dev trunk (where it has been copied from) and in the development solution it references output of ControlLibrary.csproj on non obfuscated form.

Essentially what im creating here is a folder structure to zip up and ship the ControlLibrary plus examples, hence, the need to update the reference.

Update - Solved using Powershell

Answer 1

csproj files are XML files - you can easily write a command line application to manipulate these files (adding, removing nodes etc).

You can call such a command line application from your batch file.

You can find the schema for this file at:

%windir%Microsoft.NETFramework[framework version]Microsoft.Build.xsd
