    Workspaces are immutable. That means that any method that sounds like it's going to modify the workspace will instead be returning a new instance with the changes applied.

    So you want something like:

    IWorkspace workspace = Workspace.LoadSolution("MySolution.sln");
var originalSolution = workspace.CurrentSolution;
var project = originalSolution.GetProject(originalSolution.ProjectIds.First());
IDocument doc = project.AddDocument("index.html", "<html></html>");
workspace.ApplyChanges(originalSolution, doc.Project.Solution);

    However, I'm not near a machine with Roslyn installed at the moment, so I can't guarantee this 100%.

    There are two issues here:

    1. Roslyn ISolution, IProject, and IDocument objects are immutable, so in order to see changes you would need to create a new ISolution with the changes, then call Workspace.ApplyChanges().
    2. In Roslyn, IDocument objects are only created for files that are passed to the compiler. Another way of saying this is things that are part of the Compile ItemGroup in the project file. For other files (including html files), you should use the normal Visual Studio interfaces like IVsSolution.
