我尝试重建，但没有成功. 当我打开MainPage.xaml时，对于空白应用程序会发生这种情况. 令我困扰的一件事是该错误报告中System.Runtime的假定版本为0.0.0.0，这可能是解决此问题的一个好提示吗?

I tried rebuilding, of course, with no success. It happens for blank apps, when I open MainPage.xaml. One thing that bothers me is that the supposed version of System.Runtime in this error report is 0.0.0.0, could that be a good hint for solving this?

推荐答案

我能够通过检查在Visual Studio构建过程中自动检查丢失的软件包"来解决类似的错误(允许NuGet下载丢失的软件包"为已经检查过)，然后进行重建.您可以在工具-> NuGet程序包管理器->程序包管理器设置中找到这些设置.

I was able to resolve a similar error by checking "Automatically check for missing packages during build in Visual Studio" (the "Allow NuGet to download missing packages" was already checked), then rebuilding. You can find these settings in Tools --> NuGet Package Manager --> Package Manager Settings.
