ApplicationInsights, ApplicationInsightsTelemetryWorkerService, Set EnableAdaptiveSampling in config

In a "worker" application (.net core 3.1) I have configured an ApplicationInsightsTelemetryWorkerService by:

 services.AddApplicationInsightsTelemetryWorkerService(options =>
                     {
                         options.DeveloperMode = false;
                         options.EnableAdaptiveSampling = false;
                     });

In the appsettings.json the InstrumentationKey is defined as:

  "ApplicationInsights": {
    "InstrumentationKey": "xxxx-xxxx-xxxx-xxxx-xxxx"   
    },

I want to move the "EnableAdaptiveSampling" setting from the code to json file. When I try to add it to the ApplicationInsights section like "EnableAdaptiveSampling": false, it doesn't seem to pick it up.

What is the correct way to set this in a config file

You have to read the configuration by code and set it. In .net core, there is no automatic pickup of predefined setting for adaptive sampling like InstrumentationKey. For example:

appsettings.json:

"ApplicationInsights": {
    "InstrumentationKey": "xxxx-xxxx-xxxx-xxxx-xxxx",
    "EnableAdaptiveSampling": "false"
    },

Code:

// instrumentation key is read automatically from appsettings.json
services.AddApplicationInsightsTelemetryWorkerService(options =>
                     {
                         options.DeveloperMode = false;
                         options.EnableAdaptiveSampling = hostContext.Configuration.GetValue<bool>("ApplicationInsights:EnableAdaptiveSampling");
                     });
