Can I use an appsettings json file in Azure Functions

Question

I had a doubt if I can use an appsettings.json file in Azure Functions? I referred to this documentation for environment variables: https://docs.microsoft.com/en-us/azure/azure-functions/functions-reference-csharp#environment-variables

But I am using Octopus for deployments and would really like to have appsettings version controlled.

I have tried this:

{
  "frameworks": {
    "net46": {
      "dependencies": {
        "Microsoft.Extensions.Configuration": "1.0.0",
        "Microsoft.Extensions.Configuration.Json": "1.0.0"
      }
    }
  }
}

But I'm getting the following error:

2016-11-23T15:27:03.811 (12,16): error CS0012: The type 'Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime, Version=4.0.0.0

Kindly help.

Answer 1

Only environment variables are supported for app settings and connection strings. appsettings.json is not supported.

However, you can use Azure Resource Manager (ARM) Templates to configure the settings for your Function App. Here's a blog post that describe this in more detail.
