ReactiveUI: [BUG] PropertyBindingMixins.Bind crashes

Describe the bug ReactiveUI.PropertyBindingMixins.Bind throws android.runtime.JavaProxyThrowable: System.Reflection.TargetParameterCountException: Parameter count mismatch.

Steps To Reproduce

Create new Xamarin.Android project;
Add layout with TextView;
Invoke ReactiveUI.PropertyBindingMixins.Bind inside activity to bind TextView.Text with ViewModel for example:

this.Bind(
                ViewModel,
                x => x.ImportantText,
                x => x.SuperTextView.Text);

Launch app on device;
Observe crash.

Expected behavior No crash

We tracked down the bug and the location (actually to do with some changes with the Reflection.cs file), so hopefully can get a patch out in the next few days.

Thanks @glennawatson!

FWIW, there’s no runtime problem in our Xamarin.iOS or Xamarin.Forms apps, and the Xamarin.Forms app is targeted only for Android.

It seems to be a problem unique to the Xamarin.Android runtime.

Here are some truncated logs:

We’ve passed this bug onto the Reactive Extensions team. See https://github.com/dotnet/reactive/issues/1129 to track it.

Just to add more info to this issue: Looks like this exception also happens when binding to Android.Widget.Switch and not just TextViews. Probably any two-way binding is where the crash occurs, I would guess.
