Adding Project reference programmatically

问题

Basically, after read a couple links, i tried the above code:

foreach (EnvDTE.Project proj in soln.Projects)
        {
            if (proj.Name == "BLL")
            {
                VSLangProj.VSProject vsproj = (VSLangProj.VSProject)proj.Object;                    
                vsproj.References.Add(@"C:\Teste\DAL\bin\Debug\DAL.dll");                    
            }
        }

All paths, project names, are hard-coded on purpouse, since im still testing how to achieve it.

Though it would act like if i did Project folder -> References -> Add reference -> Pick one, manually (compile time)

but after loading the solution, BLL project didnt contain any PERMANENT reference to DAL project.

I think that you forget to save modified project , you have to invoke Save at the end
