Newtonsoft.Json [8.0.3，]'在項目中不存在

Question

雖然安裝了Newtonsoft.Json 9.0.0.0，但在嘗試添加Push Notification nuget（取決於Newtonsoft.Json> = 8.0.3）時出現此錯誤。

這裏是我所得到的：

任何想法？

Answer 1

的.nuspec爲Xam.Plugin.PushNotification 1.2.2包括：

<dependency id="Newtonsoft.Json" version="8.0.3" /> 

因此，當它是解決依賴Newtonsoft.Json [8.0.3,)因爲這將是自SemVer主要版本重大更改它，如果你有Newtonsoft.Json 9.0.0安裝失敗已經改變。
