# AL0106 - Avoid Task.Run in ASP.NET Core handlers

> ASP.NET Core already runs on the thread pool, Task.Run adds overhead

Source: [Al0106AvoidTaskRunInAspNetCoreAnalyzer.cs](https://github.com/ANcpLua/ANcpLua.Analyzers/blob/main/src/ANcpLua.Analyzers/Analyzers/Al0106AvoidTaskRunInAspNetCoreAnalyzer.cs)

## Description

ASP.NET Core request handlers already execute on the thread pool. Using `Task.Run()` adds unnecessary overhead by scheduling work to another thread pool thread.

## Bad Code

```csharp theme={null}
app.MapGet("/orders", async () =>
{
    return await Task.Run(() => db.Orders.ToList());
});
```

## Good Code

```csharp theme={null}
app.MapGet("/orders", async (AppDbContext db) =>
{
    return await db.Orders.ToListAsync();
});
```

## Properties

* **Category**: ASP.NET Core
* **Severity**: Warning
* **Enabled by default**: True
* **Code fix available**: False

## Configuration

```editorconfig theme={null}
dotnet_diagnostic.AL0106.severity = warning
```
