String constants and lookup helpers for the DocumentDB versions known to this build of the package.

## Definition

```csharp
namespace Aspire.Hosting.ApplicationModel;

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

## Remarks

Per-version constants (for example [DocumentDBVersions.V0_109_0](/reference/api/csharp/aspire.hosting.documentdb/documentdbversions/fields.md#v0-109-0)) are stable strings and may safely be exposed as `const`. [DocumentDBVersions.Latest](/reference/api/csharp/aspire.hosting.documentdb/documentdbversions/properties.md#latest) is intentionally a property -- not a `const` -- so consumers re-resolve it after a NuGet upgrade rather than inlining the old value at compile time.

## Properties

- [All](/reference/api/csharp/aspire.hosting.documentdb/documentdbversions/properties.md#all) : `IReadOnlyList<string>` `static` `get` -- All DocumentDB versions known to this build of the package, sorted ascending by numeric semantic version. The order of this list is part of the contract: `All[All.Count - 1]` is always the newest known version.
- [Latest](/reference/api/csharp/aspire.hosting.documentdb/documentdbversions/properties.md#latest) : `string` `static` `get` -- The newest DocumentDB version known to this build of the package. This is the version applied by default when no explicit version is selected via [DocumentDBBuilderExtensions.WithDocumentDBVersion(IResourceBuilder<DocumentDBServerResource>, DocumentDBVersion)](/reference/api/csharp/aspire.hosting.documentdb/documentdbbuilderextensions/methods.md#withdocumentdbversion-iresourcebuilder-documentdbserverresource-documentdbversion).
