Hi, We have created Cloud Service Project using C# in VS2019. We are using Microsoft.Azure.Cosmos.Table of Version 1.0.8 for Azure Storage Table access When we are deploying the cloud service , WebRole shows "Busy. recovering role with some exception". but Worker role shows Running Status.

@sakash279 We don't intend to make StorageExceptions serializable, at the moment. You need to catch this in your code and extract the relevant information for your debugging purposes. If you handle this exception gracefully, your Cloud Service deployment shouldn't be blocked.

@christopheranderson Hi Christopher. May I ask if we could use [Serializable()] on the relevant code to solve the issue? Like:

[Serializable()] public static void Cosmos_Tables() { ... }

@WY-S You will need to copy StorageException properties to your own serializable class.
