Here's an easy way you can do it using Linq2Xml. I've included a single and a list based method. Oh, and like Casper said: you'll need to unload the project from VS before your program can edit it. Then just reload it when done.

    private static void AddFilesToUnitTestProject(FileInfo[] files, string measureBaseDirPath, string measureDataDirSuffix)
    {
        var unitTestProjectPath = measureBaseDirPath + _unitTestProjectFile;
        var unitTestProjectFile = XDocument.Load(unitTestProjectPath);
        var itemGroup = unitTestProjectFile.Nodes()
                          .OfType<XElement>()
                          .DescendantNodes()
                          .OfType<XElement>().First(xy => xy.Name.LocalName == "ItemGroup");

        foreach (var fileInfo in files)
        {
            var xelem = AddProjectContent(measureDataDirSuffix + fileInfo.Name, unitTestProjectFile);
            itemGroup.Add(xelem);
        }
        unitTestProjectFile.Save(unitTestProjectPath);
    }

    private static void AddFileToUnitTestProject(string pathToAdd, string measureBaseDirPath, string measureDataDir)
    {
        var unitTestProjectPath = measureBaseDirPath + _unitTestProjectFile;
        var unitTestProjectFile = XDocument.Load(unitTestProjectPath);
        var itemGroup =
        unitTestProjectFile.Nodes()
                           .OfType<XElement>()
                           .DescendantNodes()
                           .OfType<XElement>().First(xy => xy.Name.LocalName == "ItemGroup");
        var xelem = AddProjectContent(pathToAdd, unitTestProjectFile);
        itemGroup.Add(xelem);
        unitTestProjectFile.Save(unitTestProjectPath);
    }

private static XElement AddProjectContent(string pathToAdd, XDocument doc) 
{ 
    XNamespace rootNamespace = doc.Root.Name.NamespaceName; 
    var xelem = new XElement(rootNamespace + "Content"); 
    xelem.Add(new XAttribute("Include", pathToAdd)); 
    xelem.Add(new XElement(rootNamespace + "CopyToOutputDirectory", "Always")); 
    return xelem; 
}
  • Updated with AddProjectContent method

I don't think there's any tool that will respond to an "add-project" command on the command-line to do this, but I think you could have luck creating a program/script to manipulate the XML content of csproj files directly.

The structure of a csproj file looks like this:

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="...">
    <PropertyGroup>
        <!-- Properties which affect the build process -->
    </PropertyGroup>
    <ItemGroup>
        <!-- Groups of items to process -->
    </ItemGroup>
</Project>

To add a C# code file to a project, you just need to add a Compile element to an ItemGroup element:

<Compile Include="{relative path to file}" />

If you use an existing project file as a template, this should be possible with a very simple XSLT.

.csproj files can be used as input into the MSBuild command line tool.

See the MSBuild reference:

MS Build Reference

And for example, this question.

MSBuild — Use the .csproj file or roll your own?

You can simply use a text editor to edit them and do anything MSBuild allows. If you insert custom build actions Visual Studio might warn a developer when the project is loaded that it contains custom actions, depending on what you do.

Unload the project by right clicking it in solution explorer. Edit the project by right clicking. Add f.ex:

<Compile Include="Properties\AssemblyInfo.cs" />
