Hi - I am trying to migrate an application using Umbraco 8.17 from on prem to Azure. I have migrated the DB in Azure to SQL MI. Deployed the app to Azure, updated the connection string with the SQL MI one.

Even updated the connection string with Authentication=Active Directory Managed Identity, but still getting the below error:

-> Umbraco.Core.Exceptions.BootFailedException: Boot failed.

-> System.TimeoutException: Cannot acquire MainDom at Umbraco.Core.Runtime.MainDom.Acquire() at System.Threading.LazyInitializer.EnsureInitializedCore[T](T& target, Boolean& initialized, Object& syncLock, Func`1 valueFactory) at Umbraco.Core.Runtime.MainDom.get_IsMainDom() at Umbraco.Core.Runtime.CoreRuntime.AcquireMainDom(IMainDom mainDom) at Umbraco.Core.Runtime.CoreRuntime.Boot(IRegister register, DisposableTimer timer)

After checking the logs, error seems to be as below:

Unable to resolve type: Umbraco.Core.Services.ServiceContext, service name:

Any help would be greatly appreciated.
