Xamarin.Forms - XamlCompilation MissingMethodException

Question

Chcę poprawić wydajność aplikacji UWL Xamarin.Forms, ponieważ jest bardzo powolna w trybie Release (zaznaczono ".NET native"). Więc zastosowanie XAMLC na poziomie zespołu w projekcie PCL:

[assembly: XamlCompilation (XamlCompilationOptions.Compile)] 
namespace MyApp 
{ 
} 

ale z tego atrybutu otrzymuję błąd wykonania:

"Method not found: 'Void Xamarin.Forms.Xaml.Internals.SimpleValueTargetProvider..ctor(System.Object[])'."

Zgodnie z tym:

https://github.com/xamarin/Xamarin.Forms/blob/master/docs/Xamarin.Forms.Xaml/Xamarin.Forms.Xaml.Internals/SimpleValueTargetProvider.xml

się Klasa SimpleValueTargetProvider ma 2 wersje:

• 1.5.0.0 - konstruktor jednego parametru System.Object []
• 2.0.0.0 - konstruktor 2 Parametry System.Object [] i System.Object

stosuję Xamarin.Forms 2.3.3.163 -pre3, więc używam drugiej wersji w moim projekcie (kiedy przechodzę do SimpleValueTargetProvider w Xamarin.Forms.Xaml.Internals, widzę konstruktora z 2 parametrami). Rozumiem, że najwyraźniej "coś" nadal wywołuje SimpleValueTargetProvider 1.5.0.0, ale nie mam pojęcia, co to jest.

Usunąłem wszystkie składniki innych firm, ale to nie pomogło. Kiedyś dziennik fuzyjne, aby dowiedzieć się, co się dzieje, ale to wszystko dostać (szczerze mówiąc nie wiem, czy jest to związane z emisją mam skierowaną w ogóle):

to jest błąd w Xamarin.Forms lub XamlCTask? Czy ktoś napotkał ten problem lub wie, jak to naprawić?

• systemu Windows 10 64-bitowy
• wizualna Studion 15 Podgląd 5
• Xamarin 4.2.1.14
• Xamarin.Forms 2.3.3.163-PRE3

góry dzięki

Answer 1

Jest to najprawdopodobniej kwestia buforowania na poziomie IDE lub projektu.

Jeśli jest to na poziomie IDE: - zrobić czystą - uruchom ponownie VS lub XS - odbudować

ale prawdopodobnie próbował już.

Domyślam się, że jedna z aktualizacji nuget nie została poprawnie oczyszczona, a masz inną wersję XF, do której odwołuje się inny projekt twojego rozwiązania, lub jeden plik .csproj odwołuje się do starego pliku .targets.

Niektóre ręczne czyszczenie domu rozwiąże problem, mam nadzieję.

Answer 2

Jeśli twój projekt zależy od zespołu zewnętrznego, który używa XamlC, a ten zestaw został zbudowany na XF < 2.3.3, nadal możesz dostać ten problem.

Poprawka istnieje i zostanie wydana jako część pierwszego wydania usługi dla XF 2.3.3
