I am currently developing the Azure function on localhost. Getting this error while executing any MS graph calls: ClientSecretCredential authentication failed: Expression of type 'System.Diagnostics.Activity' cannot be used for return type 'System.Diagnostics.Activity'
Please check the source code attached below for more details.

- Timestamp:
- Function App version: V3
- Function App name:
- Function name(s) (as appropriate):
- Invocation ID:
- Region:

#### Repro steps

1. Create a new Azure functions project in VS.
2. Create MS graph client using Azure AD application : https://learn.microsoft.com/en-us/graph/sdks/choose-authentication-providers?tabs=CS#client-credentials-provider
3. Make any MS graph API call.

#### Expected behavior

Expected behavior is MS graph API calls should succeed.

#### Actual behavior

```csharp
private static void callMsGraphClient()
{
var scopes = new[] { "https://graph.microsoft.com/.default" };
var tenantId = "";
var clientId = "";
var clientSecret = "";

var options = new TokenCredentialOptions
{
AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
};
var clientSecretCredential = new ClientSecretCredential(
tenantId, clientId, clientSecret, options);

var graphClient = new GraphServiceClient(clientSecretCredential, scopes);
var users = await graphClient.Users.GetAsync();
}
```

```csharp

v3












```

Start with the callMsGraphClient reproduction and the listed .NET Framework 4.7.2, Azure Functions v3, Azure.Core, Azure.Identity, and Microsoft.Graph package versions. Reproduce a Graph call locally, then trace the authentication failure across the Functions host and dependency versions. Done means the call succeeds without the System.Diagnostics.Activity return-type error.
