How can you check if a configuration section exists in the appsettings.json
in .NET Core?
Even if a section doesn't exist, the following code will always return an instantiated instance.
e.g.
var section = this.Configuration.GetSection<TestSection>("testsection");
Query the children of Configuration and check if there is any with the name "testsection"
var sectionExists = Configuration.GetChildren().Any(item => item.Key == "testsection"));
This should return true if "testsection" exists, otherwise false.
