Getting Started

1. Install the package with NuGet

Install-Package ConfigCat.Client


dotnet add package ConfigCat.Client

2. Import ConfigCat.Client to your application

using ConfigCat.Client;

3. Go to the ConfigCat Dashboard to get your SDK Key:


4. Create a ConfigCat client instance:

var client = new ConfigCatClient("#YOUR-SDK-KEY#");

We strongly recommend using the ConfigCat Client as a Singleton object in your application.

5. Get your setting value:

var isMyAwesomeFeatureEnabled = client.GetValue("isMyAwesomeFeatureEnabled", false);


6. On application exit:


To ensure graceful shutdown of the client you should invoke .Dispose() method. (Client implements IDisposable interface)

Getting user specific setting values with Targeting

Using this feature, you will be able to get different setting values for different users in your application by passing a User Object to the GetValue() function.

Read more about Targeting here.

User currentUser = new User("435170f4-8a8b-4b67-a723-505ac7cdea92");

var isMyAwesomeFeatureEnabled = client.GetValue(
	defaultValue: false,
	user: currentUser);

Sample/Demo apps

Polling Modes

The ConfigCat SDK supports 3 different polling mechanisms to acquire the setting values from ConfigCat. After latest setting values are downloaded, they are stored in the internal cache then all requests are served from there. Read more about Polling Modes and how to use them at ConfigCat Docs.
