HI Riswan,
Did you followed the same steps below mentioned,
1. Close all instances of Visual Studio.
2. Stop the following services: AOS web service and Batch Management service.
3. Delete the package folder C:\AOSService\PackagesLocalDirectory\MyModel1. On cloud-hosted environments this folder may be located on another drive letter such as K:.
4.Restart the services that you stopped in step 1.
5.Refresh models from Visual Studio
6.In Visual Studio, perform a full database synchronization (Visual Studio > Dynamics 365 > Synchronize database).
Restarting of AOS web service and Batch Management service is important.
Let me know if you are still facing this problem.
Thanks,
Shwetha
