c# - 为什么 VS Studio 2019 构建失败，找不到 Microsoft.Azure.WebJobs.Host，但 dotnet 构建成功？

Question

我有一个 Azure Functions 项目，其中创建了一个 Durable Function。当我想在 VS 2019 中构建这个项目时，出现以下错误。但是 dotnet build 成功了，我也可以从 Rider 构建项目。

没有像Microsoft.Azure.WebJobs.Host这样的包，或者至少我没有在Nuget包管理器中找到它。

这里出了什么问题？我无法决定VS是对的，还是Rider/命令行是对的。

WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

由于某些原因，.csproj 文件中的 AzureFunctionsVersion 未正确设置。我有以下内容，该项目在 VS 2019 中编译也没有任何错误。

<AzureFunctionsVersion>v2</AzureFunctionsVersion>
