全新安装 Visual Studio 2017 后，项目抛出 System.IO.FileNotFoundException
After fresh install of Visual Studio 2017, project throws System.IO.FileNotFoundException
我刚刚重置了我的电脑，安装了 Visual Studio 2017，并启动了一个 C# WPF 项目，该项目在我重置我的机器（在 2017 RC 中）之前可以工作，现在可以在其他机器上工作。该项目引用了一个名为 Eagle.Core 的 dll。我在 Debug 中启动它，在 Eagle.Core:
中调用扩展方法 (ObservableCollection.ObservableWhere([lamda])) 时得到了 System.IO.FileNotFoundException
System.IO.FileNotFoundException occurred
HResult=0x80070002
Message=Could not load file or assembly 'System.Reactive.Linq, Version=3.0.0.0, Culture=neutral, PublicKeyToken=94bc3704cddfc263' or one of its dependencies. The system cannot find the file specified.
Source=Eagle.Core
StackTrace:
at Eagle.Core.Utilities.PclWeakEventManager3.AddHandler(TEventSource source, TEventHandler handler, Func2 converter, Action1 add, Action1 remove)
at Eagle.Core.Collections.ObservableQueriedCollection2..ctor(ICollection1 source, IEnumerable1 initItems, LambdaExpression expression)
at Eagle.Core.Collections.ObservableFilteredCollection1..ctor(ICollection1 source, Expression1 filterExpression)
at ObservableCollectionExtensions.ObservableWhere[T](ICollection1 source, Expression1 filterExpression)
at TestWpf2017.MainWindow..ctor() in C:\Builds\Personal\Projects\TestWpf2017\TestWpf2017\MainWindow.xaml.cs:line 34
为了保险起见，我新建了一个WPF项目并引用了Eagle.Core并调用了同样的方法，果然，问题又出现了。
有什么建议吗？

我想这与我的 Visual Studio 安装有关。我第一次安装它时遇到了一些麻烦，我已经安装了 Visual Studio 的核心（没有选择工作负载）然后修改它以添加我需要的其他东西。
出现这个问题后，我修复了Visual Studio。我希望我不必卸载并重新安装。我什至怀疑这会有所帮助。 :(
