Visual Studio extension: Change the hint path of an assembly reference

Question

I'm writing a Visual Studio extension and I would like to change the hint path of an assembly reference of a C#-project without to trigger the "File Modification Detected"-dialog.

<Reference Include="SomeAssembly">
  <HintPath>C:\ChangeMe\SomeAssembly.dll</HintPath>
</Reference>

But in the VSLangProj110.Reference5-interface I can't find any property that I can use. (Accessed through VSLangProj140.VSProject3.References)

Answer 1

Microsoft.Build.BuildEngine.Project is outdated. Here is an updated working solution.

foreach (var dteProject in dte.Solution.Projects.OfType<Project>())
{
    // You can edit the project through an object of Microsoft.Build.Evaluation.Project 
    var buildProject = ProjectCollection.GlobalProjectCollection.GetLoadedProjects(dteProject.FullName).First();
    foreach (var item in buildProject.Items.Where(obj => obj.ItemType == "Reference"))
    {
        var newPath = SomeMethod(item.GetMetadata("HintPath"));

        item.SetMetadataValue("HintPath", newPath);
    }

    // But you have to save through an object of EnvDTE.Project
    dteProject.Save();
}
