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