# LegacyGrainId

Package: [Microsoft.Orleans.Core.Abstractions](/orleans/docs/api/csharp/microsoft.orleans.core.abstractions/) 10.0.0

[NuGet package](https://www.nuget.org/packages/Microsoft.Orleans.Core.Abstractions) | [Source](https://github.com/dotnet/orleans/blob/e4e752cedecc2976811db49802c7a999b1f1c704/src/Orleans.Core.Abstractions/IDs/Legacy/LegacyGrainId.cs#L12)

```csharp
[Orleans.GenerateSerializer]
[Orleans.Immutable]
public sealed class LegacyGrainId : IComparable<LegacyGrainId>, IEquatable<LegacyGrainId>
```

Supports all classes in the .NET class hierarchy and provides low-level services to derived classes. This is the ultimate base class of all .NET classes; it is the root of the type hierarchy.
