Wix# Bundle doesn't support MspPackage directly. Please add it as a feature request on GitHub/WixSharp (the current home of Wix#).

In a mean time you can ad the element manually. I have extended the Bootstrapper sample with the demo for adding MspPackage element:
bootstrapper.WixSourceGenerated +=
                          (doc) => doc.FindSingle("Chain")
                                      .AddElement("MspPackage", 
                                                  "SourceFile=Patch.msp; Slipstream=no");
