错误索引方法“Class.Method"无法将参数“log"绑定到类型 TraceWriter

Error indexing method #39;Class.Method#39; Cannot bind parameter #39;log#39; to type TraceWriter(错误索引方法“Class.Method无法将参数“log绑定到类型 TraceWriter)

问题描述

我已将一堆 Azure Functions 升级"到 .netstandard 2.0，但出现以下错误:

错误索引方法Class.Method"无法将参数log"绑定到键入 TraceWriter.确保参数 Type 受支持捆绑.如果您使用绑定扩展(例如 ServiceBus、Timers、等)确保你已经调用了注册方法启动代码中的扩展名(例如 config.UseServiceBus()，config.UseTimers() 等).

按照

I have "upgraded" a bunch of my Azure Functions to .netstandard 2.0 and I get the following error:

Error indexing method 'Class.Method' Cannot bind parameter 'log' to type TraceWriter. Make sure the parameter Type is supported by the binding. If you're using binding extensions (e.g. ServiceBus, Timers, etc.) make sure you've called the registration method for the extension(s) in your startup code (e.g. config.UseServiceBus(), config.UseTimers(), etc.).

Following the answer to that question, I made sure I have the latest version of Azure Functions and Web Jobs Tools: it is running 15.0.40322.0. Still, I have the same error.

I know Azure Functions running .netstandard 2.0 is in beta.

What did I miss?

To make it works, turns out I had to:

• Delete the old Function App;
• Create a new one;
• In Function App settings, set the runtime version to beta;
• Publish the Azure Functions.
