This feature was introduced in OData.NET 8.
Microsoft.OData.Client
uses HttpClient
by default, but this document will guide you on how to configure HttpClient
by providing settings like timeouts and custom handlers using IHttpClientFactory
.
IHttpClientFactory
is a feature in .NET Core that helps you manage HttpClient
instances. Here are some benefits:
- Automatic Management: It handles the lifecycle of
HttpClient
instances, preventing issues like socket exhaustion. - Configuration: You can set up policies like retries and timeouts.
- Dependency Injection: It integrates with .NET Core's DI system, making it easy to use in your services.
To customize HttpClient
with Microsoft.OData.Client
, you can use the HttpClientFactory
property of DataServiceContext
. This lets you inject your custom HttpClient
instance.
You can use the IHttpClientFactory with .NET
to configure and inject HttpClient
instances.
Note that we use an
empty string
here sinceOData Client
does not detectnamed clients
.
Here's how:
var services = new ServiceCollection();
services.AddHttpClient("", client => // We should use an empty string here since OData Client does not detect named clients.
{
client.Timeout = TimeSpan.FromSeconds(160);
});
var serviceProvider = services.BuildServiceProvider();
var httpClientFactory = serviceProvider.GetRequiredService();
var context = new Container(new Uri("{Your endpoint here. For example, https://localhost:7214/odata}"))
{
HttpClientFactory = httpClientFactory
};
Alternatively, you can create a custom HttpClientFactory
:
public class CustomHttpClientFactory : IHttpClientFactory
{
private readonly HttpClient _httpClient;
public CustomHttpClientFactory(HttpClient httpClient)
{
_httpClient = httpClient;
}
public HttpClient CreateClient(string name)
{
return _httpClient;
}
}
Next, create an HttpClient
instance and set the timeout:
var httpClient = new HttpClient
{
Timeout = TimeSpan.FromSeconds(160)
};
var httpClientFactory = new CustomHttpClientFactory(httpClient);
var context = new Container(new Uri("{Your endpoint here. For example, https://localhost:7214/odata}"))
{
HttpClientFactory = httpClientFactory
};

Using IHttpClientFactory
with Microsoft.OData.Client
makes managing and customizing HttpClient
instances easier. Whether you create a custom HttpClientFactory
or use the DI system, integrating HttpClient
with your OData client is straightforward.
Happy coding!
