[BUG] Azure.ResourceManager.Resources ResourcesOperations Slow Response.

Describe the bug Hello MS team, we met a problem that when we create/delete an Azure resource (for example virtual machine image/disk) in Azure Portal, it takes about 20 minutes for the change to eventually update in the result of calling the Azure ResourceManager SDK.

Specifically when calling the ResourcesOperations::ListAsync function with the filter string passed in to get resources of type "Microsoft.Compute/images" and type "Microsoft.Compute/snapshots" in a subscription.

(Function doc is here: https://docs.microsoft.com/en-us/dotnet/api/azure.resourcemanager.resources.resourcesoperations.listasync?view=azure-dotnet-preview)

Expected behavior Calling ListAsync should return the updated list of resources in the subscription without waiting for a long time.

Actual behavior (include Exception or Stack Trace) When calling ListAsync, it takes about 20 minutes to return the updated list of resources. Before that the returned list of resources is outdated and did not reflect the changes been made.

Environment: <PackageReference Include="Azure.ResourceManager.Resources" Version="1.0.0-preview.2" />

@grizzlytheodore , can you pass to the right team member to see if this is an ARM issue or Compute issue, please? Thank you.

@snaheth thx for response. I am taking this from @zep-uipath .

The issue only happens when we use .Net Azure ResourceManager SDK. But not able to repro thru Portal or CLI. So I doubt it is a ARM side issue. (When list thru Portal or cli, we can see the resource immediately)

➜  jingtao.ren az resource list -g Jingtao-Personal-RG --resource-type "Microsoft.Compute/snapshots" -o table
Name     ResourceGroup        Location    Type                         Status
-------  -------------------  ----------  ---------------------------  --------
winsnap  Jingtao-Personal-RG  westus2     Microsoft.Compute/snapshots

Here is how we use this query in SDK var resources = await azureClient.Resources.ListAsync(filter: $"resourceType eq 'Microsoft.Compute/images' or resourceType eq 'Microsoft.Compute/galleries/images/versions'" + $" or resourceType eq 'Microsoft.Compute/snapshots'").ToListAsync(cancellationToken);

Is this because how we construct the query ?
