## Language

- Name: `Language`
- Modifiers: `abstract` `get`
- Returns: `string`

Gets the target language name (for example, "TypeScript"). This must match the [ICodeGenerator.Language](/reference/api/csharp/aspire.typesystem/icodegenerator/properties.md#language) value of the generator that produces the same surface, so a host can resolve one from the other.

```csharp
public abstract string Language { get; }
```
