# Microsoft.Extensions.Logging.Debug

**Kind:** Service

**Source:** `Pams/Web/Pams.Web/Pams.Web.csproj` (line 1)

**Part of:** [Pams](subsystem-pams)

NuGet package dependency

`Microsoft.Extensions.Logging.Debug` is a NuGet dependency declared by `Pams.Web.csproj`. It adds the .NET debug logging provider, allowing application log entries to be written to the debugger output when the web project configures debug logging.

    participant App as Pams.Web
    participant Logging as ILogger
    participant Debug as Debug Logger Provider
    participant Output as Debug Output

    App->>Logging: LogInformation(message)
    Logging->>Debug: Write log entry
    Debug->>Output: Emit formatted message
```

## Usage

```ts
import { spawn } from "node:child_process";

const app = spawn("dotnet", ["run", "--project", "Pams/Web/Pams.Web/Pams.Web.csproj"], {
  env: {
    ...process.env,
    Logging__LogLevel__Default: "Debug",
  },
  stdio: "inherit",
});

app.on("exit", (code) => {
  console.log(`Pams.Web exited with code ${code}`);
});
```

## AI Coding Instructions

- Keep `Microsoft.Extensions.Logging.Debug` declared as a package dependency in `Pams.Web.csproj` when debug logger output is required.
- Configure the provider in the .NET application startup code with `AddDebug()` before expecting debug output.
- Use `ILogger<T>` through dependency injection rather than creating logger instances directly.
- Check the active log-level configuration when debug messages do not appear; `Debug` entries can be filtered by application settings.
