Problem with TimerInfo in Azure functions .net 5 version

[jmaragon]

When using Timer binding function, the TimerInfo object is available in Microsoft.Azure.WebJobs.Extension package, but when that package is added to the project, there is a ambiguity within TimerTriggerAttribute, as it is defined both in Microsoft.Azure.WebJobs.Extension and in Microsoft Azure Functions.

Please clarify how to support binding to TimerInfo injected class should be done.

Thanks

Hello @jmaragon - Could you elaborate on the ambiguity part more? Both the TimerInfo and the TimerTriggerAttribute types are under the same Microsoft.Azure.WebJobs namespace: https://github.com/Azure/azure-webjobs-sdk-extensions/tree/dev/src/WebJobs.Extensions/Extensions/Timers

Ambiguity is in TimerTriggerAttribute, which exists both in Microsoft.Azure.WebJobs and Microsoft.Azure.Functions.Worker namespaces.

Resolving ambiguity to WebJobs causes error AZFW0001, as WebJobsAttribute is not supported in .NET Worker (Isolated Process)

Resolving ambiguity to Functions.Worker causes function to throw an exception:

System.Private.CoreLib: Exception while executing function: Functions.PrintingFilesCleanup. System.Private.CoreLib: Result: Failure Exception: Microsoft.Azure.Functions.Worker.Diagnostics.Exceptions.FunctionInputConverterException: Error converting 1 input parameters for Function 'PrintingFilesCleanup': Cannot convert input parameter 'myTimer' to type 'Microsoft.Azure.WebJobs.TimerInfo' from type 'System.String'.

Now even I am stuck with this. What a nightmare.

I was able to fix this issue by updating the Microsoft.Azure.Functions.Worker.Extensions.Timer package to 4.3.0, TimerInfo has been added to the package in this version.
