you need to pass a bundle instance, or a Parcelable java class instance. .net does not support this directly. you create a java class, with Parcelable support. then import this class in .net. you then load the properties, and pass to intent.PutExtra()

sample:

note: if you use this for several windows, I'd create a class that just passed a single string (you might be able to use the Bundle directly). then I'd pass a json string. (the bundle serializes, so you are not passing an object instance).
