## Cause
|

|
|
||
|
|
`ConfigureServices` isn't the recommended strategy for registering services in DI in a minimal API application.

## Rule description
|
||
|
|
|
||
|
|
`ConfigureServices` isn't the recommended strategy for configuring logging in a minimal API application.
|
||
|
|
|
||
|
|
```csharp
|
||
|
|
var builder = WebApplication.CreateBuilder(args);
|
||
|
|
|
||
|
|
builder.Host.ConfigureServices(services =>
|
||
|
|
{
|
||
|
|
services.AddAntiforgery();
|
||
|
|
})
|
||
|
|
|
||
|
|
var app = builder.Build();
|
||
|
|
|
||
|
|
app.Run();
|
||
|
|
```
|
||
|
|
|
||
|
|
## How to fix violations
|
||
|
|
|
||
|
|
To fix a violation of this rule, use the `Services` property on the `WebApplicationBuilder` to modify the DI container directly without the need for an additional `ConfigureServices` call.
|
||
|
|
|
||
|
|
```csharp
|
||
|
|
var builder = WebApplication.CreateBuilder(args);
|
||
|
|
|
||
|
|
builder.Services.AddAntiforgery();
|
||
|
|
|
||
|
|
var app = builder.Build();
|
||
|
|
|
||
|
|
app.Run();
|
||
|
|
```
|
||
|
|
|
||
|
|
## When to suppress warnings
|
||
|
|
|
||
|
|
Do ***not*** suppress a warning from this rule.
