+linkTitle: "AI"
+weight: 10000
+description: How to get up and running with the Dapr AI .NET SDK
+no_list: true
+---
+
+The Dapr AI client package allows you to interact with the AI capabilities provided by the Dapr sidecar.
+
+## Installation
+
+To get started with the Dapr AI .NET SDK client, install the following package from NuGet:
+```sh
+dotnet add package Dapr.AI
+```
+
+A `DaprConversationClient` holes access to networking resources in the form of TCP sockets used to communicate with the Dapr sidecar. 
+
+### Dependency Injection
+
+The `AddDaprAiConversation()` method will register the Dapr client ASP.NET Core dependency injection and is the recommended approach
+for using this package. This method accepts an optional options delegate for configuring the `DaprConversationClient` and a
+`ServiceLifetime` argument, allowing you to specify a different lifetime for the registered services instead of the default `Singleton`
+value.
+
+The following example assumes all default values are acceptable and is sufficient to register the `DaprConversationClient`:
+
+```csharp
+services.AddDaprAiConversation();
+```
+
+The optional configuration delegate is used to configure the `DaprConversationClient` by specifying options on the 
+`DaprConversationClientBuilder` as in the following example:
+```csharp
+services.AddSingleton<DefaultOptionsProvider>();
+services.AddDaprAiConversation((serviceProvider, clientBuilder) => {
+     //Inject a service to source a value from
+     var optionsProvider = serviceProvider.GetRequiredService<DefaultOptionsProvider>();
+     var standardTimeout = optionsProvider.GetStandardTimeout();
+
+     //Configure the value on the client builder
+     clientBuilder.UseTimeout(standardTimeout);
+});
+```
+
+### Manual Instantiation
+Rather than using dependency injection, a `DaprConversationClient` can also be built using the static client builder.
+
+For best performance, create a single long-lived instance of `DaprConversationClient` and provide access to that shared instance throughout
+your application. `DaprConversationClient` instances are thread-safe and intended to be shared. 
+
+Avoid creating a `DaprConversationClient` per-operation.
+
+A `DaprConversationClient` can be configured by invoking methods on the `DaprConversationClientBuilder` class before calling `.Build()`
+to create the client. The settings for each `DaprConversationClient` are separate and cannot be changed after calling `.Build()`.
+
+```csharp
+var daprConversationClient = new DaprConversationClientBuilder()
+    .UseJsonSerializerSettings( ... ) //Configure JSON serializer
+    .Build();
+```
+
+See the .NET [documentation here]({{< ref dotnet-client >}}) for more information about the options available when configuring the Dapr client via the builder.

+This part of the .NET SDK allows you to interface with the Conversations API to send and receive messages from
+large language models.
