BottomNavigationBarXF: Keep getting System.InvalidOperationException: Sequence contains no matching element

Can you please document how to use this control? I have looked at the source code which compiles and runs fine, but when I use the nuget package instead, I’m getting a runtime exception.

To understand the difference, I added the following to both projects, mine and yours, to compare the difference and find why it’s failing to find methodName == SendAppearing:

        foreach (var item in _targetMethodInfoList)
                Console.WriteLine(item.Name);

The difference was here: and here:

So I think to fix this, you need to change ANY line to use .Contains() after prefix it with . dot along with == in ReflectedProxy.cs

_cachedMethodInfo[methodName] = _targetMethodInfoList.Single(mi => mi.Name == methodName || mi.Name.Contains("." + methodName));

_cachedPropertyInfo[propertyName] = _targetPropertyInfoList.Single(pi => pi.Name == propertyName || pi.Name.Contains("." + propertyName));

@malokuS sorry for the delay, we’re on it 😃

I’m still getting this using the NuGet Package ThriveGmbH.BottomNavigationBar.XF 1.0.0.
