Compatibility

The .NET Tracer supports all .NET-based languages (for example, C#, F#, Visual Basic).
The .NET Tracer supports instrumentation on .NET Framework 4.5 and above. It also supports .NET Core.
The .NET Tracer library for Datadog is open-source. For more information see the tracer Github repository.

Notes:

Datadog automatic instrumentation relies on the .NET CLR Profiling API. This API allows only one subscriber (for example, APM). To ensure maximum visibility, run only one APM solution within your application environment.
If you are using both automatic and custom instrumentation, it is important to keep the package versions (for example, MSI and NuGet) in sync.

Integrations

The .NET Tracer can instrument the following libraries automatically:

Framework or library	NuGet package	Integration Name
ASP.NET (including Web Forms)	built-in	`AspNet`
ASP.NET MVC	`Microsoft.AspNet.Mvc` 4.0+	`AspNetMvc`
ASP.NET Web API 2	`Microsoft.AspNet.WebApi` 5.1+	`AspNetWebApi2`
WCF (server)	built-in	`Wcf`
ADO.NET	built-in	`AdoNet`
HttpClient / HttpMessageHandler	built-in	`HttpMessageHandler`
WebClient / WebRequest	built-in	`WebRequest`
Redis (StackExchange client)	`StackExchange.Redis` 1.0.187+	`StackExchangeRedis`
Redis (ServiceStack client)	`ServiceStack.Redis` 4.0.48+	`ServiceStackRedis`
Elasticsearch	`Elasticsearch.Net` 5.3.0+	`ElasticsearchNet`
MongoDB	`MongoDB.Driver.Core` 2.1.0+	`MongoDb`
PostgreSQL	`Npgsql` 4.0+	`AdoNet`
RabbitMQ	`RabbitMQ.Client` 3.6.9+	`RabbitMQ`

Note: The ADO.NET integration instruments calls made through the DbCommand abstract class or the IDbCommand interface, regardless of the underlying implementation. It also instruments direct calls to SqlCommand and NpgsqlCommand.
