[QUERY] TokenCredential vs ServiceClientCredentials

[andrei-faber]

Query/Question
I have a C# function application with a system-assigned managed identity, and I need to use SynapseManagementClient from this app.
I authenticate using DefaultAzureCredential and that's enough to work with services that require TokenCredential (for instance ArmClient), but SynapseManagementClient requires ServiceClientCredentials instead which is not compatible with TokenCredential. How do I convert the credentials?

Environment:
Azure.Identity
Azure.ResourceManager
Microsoft.Azure.Management.Synapse

Thank you for your feedback. Tagging and routing to the team members best able to assist.

Assuming the synapse management plan would take a bearer token, I assume one could implement a ServiceClientCredentials that wraps a TokenCredential, but I think it depends more on the specific auth that the management plane requires.

@christothes how do I properly get bearer token from it?

Hi, we also came across this ... it would be nice if all Microsoft.Azure.Management.* libraries could support Azure.Identity.

@andrei-faber, @sopelt thank for reaching us.
Microsoft.Azure.Management.* is track 1 that not support Azure.Identity, and only the new Azure.ResourceManager.* track 2 support.
To Synapse, we will upgrade it to track 2 soon
