Solved:I was using wrong Static Resourcei was writingStyle="{StaticResource AddHwType }"and it should be Style="{StaticResource AppButtons}":)
解决：我用错了Static Resource我写的Style="{StaticResource AddHwType }"，它应该是Style="{StaticResource AppButtons}":)
回答by Bas
It seems that one of the StaticResources used does not exist:
似乎StaticResource使用的s之一不存在：
Either:
任何一个：
AddHwType(Button Style)AppButtons(Button Style)BooleanToVisibilityConverter(Converter)
AddHwType（按钮样式）AppButtons（按钮样式）BooleanToVisibilityConverter(转换器)
You might miss a merged dictionary somewhere or forgot to add a resource before using it. Review the XAML Resources page on MSDNfor more info.
