Azure Function：无法加载文件或程序集 Newtonsoft.Json

Question

I'm aware that this issue is widely covered on the web and at stackoverflow but I could do with some extra help to sort this issue. I'm getting a runtime error relating to loading Newtonsoft, see below;

[11/07/2020 18:37:17] A ScriptHost error has occurred
[11/07/2020 18:37:17] Exception while executing function: Alerts. EmailSender: Could not load file or assembly 'Newtonsoft.Json, Version=12.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies.

I have followed and implemented binding redirects as described in this blog . My azure function is a verion 1 function with .net472, im using Microsoft.NET.Sdk.Functions Version 1.0.36.

The exception occurs when a call to a referenced project is made, in that project there is a reference to Newtonsoft 10.0.2.

Any help is greatly appreciated - thanks!

You'll need to downgrade Newtonsoft to 9.0.1. You'd better read about the v1/v2 breaking changes and rewrite your function to .net core.
