## Definition

```csharp
namespace Aspire.Hosting.ApplicationModel;

public class NetworkEndpointSnapshotList
    : System.Collections.Generic.IEnumerable<Aspire.Hosting.ApplicationModel.NetworkEndpointSnapshot>,
      System.Collections.IEnumerable
{
    // ...
}
```

## Constructors

- [NetworkEndpointSnapshotList](/reference/api/csharp/aspire.hosting/networkendpointsnapshotlist/constructors.md#constructor)

## Methods

- [AddOrUpdateAllocatedEndpoint(NetworkIdentifier, AllocatedEndpoint)](/reference/api/csharp/aspire.hosting/networkendpointsnapshotlist/methods.md#addorupdateallocatedendpoint-networkidentifier-allocatedendpoint) -- Adds or updates an AllocatedEndpoint value associated with a specific network in the snapshot list.
- [GetAllocatedEndpointAsync(NetworkIdentifier, CancellationToken)](/reference/api/csharp/aspire.hosting/networkendpointsnapshotlist/methods.md#getallocatedendpointasync-networkidentifier-cancellationtoken) : [Task<AllocatedEndpoint>](/reference/api/csharp/aspire.hosting/allocatedendpoint.md) -- Gets an AllocatedEndpoint for a given network ID, waiting for it to appear if it is not already present.
- [GetEnumerator](/reference/api/csharp/aspire.hosting/networkendpointsnapshotlist/methods.md#getenumerator) : [IEnumerator<NetworkEndpointSnapshot>](/reference/api/csharp/aspire.hosting/networkendpointsnapshot.md) -- Provides a thread-safe enumerator over the network endpoint snapshots.
- [TryAdd(NetworkIdentifier, ValueSnapshot<AllocatedEndpoint>)](/reference/api/csharp/aspire.hosting/networkendpointsnapshotlist/methods.md#tryadd-networkidentifier-valuesnapshot-allocatedendpoint) : `bool` `obsolete` -- Adds an AllocatedEndpoint snapshot for a specific network if one does not already exist.
