Forms 3.0: System.Reflection.AmbiguousMatchException #2632

Closed Sebastian1989101 closed 6 years ago

Sebastian1989101 commented 6 years ago

After the update to Xamarin.Forms 3.0 I got AmbiguousMatchException all over the place in my code. I'm not 100% why this happens and what it causes yet. A friend of mine got the same exceptions after the update - he has a complete different coding style and uses complete different libraries. Sadly he dosn't know why this happen and where it comes from. 

System.Reflection.AmbiguousMatchException: Ambiguous match found.

I just migrate from Xamarin Forms 2.5 to 3.1.0 and everything failed with AmbiguousMatchException at application start :(

godrose commented 6 years ago

You should clean and rebuild. This issue has been fixed in the June version.

I'm getting this error since I upgraded from Xamarin 2.5 to 3.2. I removed all the "Source={x:Reference Page}}" in my xaml file but still the error is there. any ideas what else can be the cause?

StephaneDelcroix commented 6 years ago

@alicint please open a new issue, with a reproduction. thx

txarito commented 5 years ago

Hello, i'm getting this error on new Project. VS2017 15.9.3, Xamarin Forms 3.4.0.1008975, .net Estándar 2.0 Page definition: <ContentPage x:Name="ViewX"...> In a control: Parent="{x:Reference ViewX}"

Remove last line solve runtime error, but obviously it's doens't works as expected.

Any workaround, solution?.

Many thanks
