How to Impliment LaunchDarkly feature management in .net core api

I would like to add LaunchDarkly feature management in my .net core api.In a real time project how can i add this?

I have one interface file with all features.How will be this interface participate in LD call?

i am confused how to create a generic file for the configuration and call to different controllers! any help will be appreciated!

what I have did in my sample program..

1. I created a flag in the LD website and added below code to main

Configuration ldConfig = LaunchDarkly.Client.Configuration

// TODO: Enter your LaunchDarkly SDK key here

.Default("YOUR_SDK_KEY");

LdClient client = new LdClient(ldConfig);

User user = User.Builder("[email protected]")

.FirstName("Bob")

.LastName("Loblaw")

.Custom("groups", "beta_testers")

.Build();

// TODO: Enter the key for your feature flag key here

var value = client.BoolVariation("YOUR_FEATURE_FLAG_KEY", user, false);

if (value)

{

Console.WriteLine("Showing feature for user " + user.Key);

}

else

{

Console.WriteLine("Not showing feature for user " + user.Key);

}

But now i have a real time api project with huge lines of code, multiple controllers.How can i make this LD class generic? please help me..thanks
