Well-known launch configuration type identifiers.

## Definition

```csharp
namespace Aspire.Hosting.ApplicationModel;

public static class KnownLaunchConfigurationTypes
{
    // ...
}
```

## Remarks

The launch configuration type tells the IDE which launcher to use for a resource. Integrations are free to define their own identifiers (for example `"go"` or `"python"`); only the identifiers that Aspire itself gives special meaning to are listed here.
