# OpenTracing instrumentation for .NET Core apps
This repository provides OpenTracing instrumentation for .NET Core based applications.
It can be used with any OpenTracing compatible tracer.
_**IMPORTANT:** OpenTracing and OpenCensus have merget to form **[OpenTelemetry](https://opentelemetry.io)**! The OpenTelemetry .NET library can be found at [https://github.com/open-telemetry/opentelemetry-dotnet](https://github.com/open-telemetry/opentelemetry-dotnet)._
## Supported .NET versions
This project currently only supports apps targeting .NET Core 3.1, .NET 6.0, or .NET 7.0!
This project DOES NOT support the full .NET framework as that uses different instrumentation code.
## Supported libraries and frameworks
#### DiagnosticSource based instrumentation
This project supports any library or framework that uses .NET's [`DiagnosticSource`](https://github.com/dotnet/runtime/blob/master/src/libraries/System.Diagnostics.DiagnosticSource/src/DiagnosticSourceUsersGuide.md)
to instrument its code. It will create a span for every [`Activity`](https://github.com/dotnet/runtime/blob/master/src/libraries/System.Diagnostics.DiagnosticSource/src/ActivityUserGuide.md)
and it will create `span.Log` calls for all other diagnostic events.
To further improve the tracing output, the library provides enhanced instrumentation
(Inject/Extract, tags, configuration options) for the following libraries / frameworks:
* ASP.NET Core
* Entity Framework Core
* System.Net.Http (HttpClient)
* System.Data.SqlClient
* Microsoft.Data.SqlClient
#### Microsoft.Extensions.Logging based instrumentation
This project also adds itself as a logger provider for logging events from the `Microsoft.Extensions.Logging` system.
It will create `span.Log` calls for each logging event, however it will only create them if there is an active span (`ITracer.ActiveSpan`).
## Usage
This project depends on several packages from Microsofts `Microsoft.Extensions.*` stack (e.g. Dependency Injection, Logging)
so its main use case is ASP.NET Core apps and any other Microsoft.Extensions-based console apps.
##### 1. Add the NuGet package `OpenTracing.Contrib.NetCore` to your project.
##### 2. Add the OpenTracing services to your `IServiceCollection` via `services.AddOpenTracing()`.
How you do this depends on how you've setup the `Microsoft.Extensions.DependencyInjection` system in your app.
In ASP.NET Core apps you can add the call to your `ConfigureServices` method (of your `Program.cs` file):
```csharp
public static IWebHost BuildWebHost(string[] args)
{
return WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.ConfigureServices(services =>
{
// Enables and automatically starts the instrumentation!
services.AddOpenTracing();
})
.Build();
}
```
##### 3. Make sure `InstrumentationService`, which implements `IHostedService`, is started.
`InstrumentationService` is responsible for starting and stopping the instrumentation.
The service implements `IHostedService` so **it is automatically started in ASP.NET Core**,
however if you have your own console host, you manually have to call `StartAsync` and `StopAsync`.
Note that .NET Core 2.1 greatly simplified this setup by introducing a generic `HostBuilder` that works similar to the existing `WebHostBuilder` from ASP.NET Core. Have a look at the `TrafficGenerator` sample for an example of a `HostBuilder` based console application.

# Release Process
The release process consists of these steps:
1. Create a GitHub release with release notes. The tag name must be a semantic version, prefixed with "v" - e.g. `v0.1.0` or `v0.1.0-rc1`
1. Wait for the AppVeyor build to finish the *tag* build: https://ci.appveyor.com/project/opentracing/csharp-netcore
1. As a signed-in AppVeyor user, click "Deploy" on the build details page and select "NuGet (OpenTracing)".
This will upload the packages to NuGet.org
