---编辑--- 确保我使用了正确的运行时，现在会产生以下错误

我确实安装了2.2.0-preview1-35029

这是由于在旧函数运行时

2.0.11960.0

中引用了

Microsoft.Azure.WebJobs.Extensions.CosmosDB

的最新版本

3.0.1-beta1/2

Microsoft.NET.Sdk.Functions 1.0.19

和

Microsoft.Azure.WebJobs.Extensions.CosmosDB 3.0.1-beta2

取决于运行时

2.0.12050.0

使用相关错误信息检查此项，以中断最新运行时的更改

2.0.12050.0

如果您现在不想移动到最新的运行时，请将

Microsoft.Azure.WebJobs.Extensions.CosmosDB

降级为

3.0.0-beta7

，并将

Microsoft.NET.Sdk.Functions

降级为

1.0.14

否则只需确保VS使用最新的函数runtime

2.0.12050.0

在VS菜单->扩展和更新上。查找Azure功能和Web作业工具。确保它>=15.8.5023。（需要先将VS更新为15.8）

删除旧功能核心工具（Cli）文件夹

%localappdata%\AzureFunctionsTools

重新启动VS并创建新的Azure函数。在“创建”对话框等待VS下载新的Cli和模板，直到我们看到对更新的提示更改就绪

更新

检查Cli输出，恐怕正在使用旧版本2.0.11651.0

Starting Host (HostId=xxx, InstanceId=xxx, Version=2.0.11651.0, ...)

转到

%localappdata%\AzureFunctionsTools\Releases

，您可能还会看到一个空文件夹

2.5.1

由于网络等原因，下载失败。再次重复上述步骤。如果无法工作，请尝试手动下载Cli。接近或领先

1）。打开

%localappdata%\AzureFunctionsTools\feed.json

查找v2的最新下载url

e、 g.cli:

2）。将解压后的文件夹重命名为

cli

，将其置于

2.5.1

下

3）。将

cli

文件夹中的

templates

文件夹移动到

2.5.1

4）。在

2.5.1

下创建manifest.json（更改用户名）

函数SDK参考了Microsoft.AspNetCore.Mvc.Abstractions 2.1.0的设计。删除

2.2.0-preview1-35029

，否则执行时可能会出错

Microsoft.Azure.WebJobs.Host: Exception binding parameter 'req'. System.Private.CoreLib: Cannot create an abstract class.

这是由于在旧函数运行时中引用了最新版本

3.0.1-beta1/2

的

Microsoft.Azure.WebJobs.Extensions.CosmosDB

Microsoft.NET.Sdk.Functions 1.0.19

和

Microsoft.Azure.WebJobs.Extensions.CosmosDB 3.0.1-beta2
