.NetCore CI pipeline error on docker tasks

I am creating a CI pipeline in Azure for a .NetCore 3.1 application and adding Docker "buildandpush" tasks. i have 2 cases, if i run only .Netcore tasks (restore, build, test, publish) my build success With out any error, if i disable above .NetCore tasks and run only docker(buildAndpublish) Tasks my build success and image pushed into my ACR, but if I enable above .NetCore tasks along with Docker tasks throw an error here.
Can any one tell me the Build definition of .netCore tasks, is i am doing the right things.

ERROR

You can use two agent jobs to run your pipeline. On agent job to run the dotnet tasks and the second to run the docker task.

If you are using classic view build pipeline. You can click on the (...) on the Pipeline to add an agent job. Please check below screenshot.

enter image description here

Then run docker tasks in agent job2 and configure agent job2 to depend the successful run of agent job1. Please check below screenshot.

If you are using yaml pipeline. You can define multiple jobs. You can check here for more information.

Update:

Here is an example to build and push to ACR in Microsoft. You donot need to use dotnet tasks to build and publish your project only to check if the build is successful or not, since your dockfile is just repeating the the same dotnet commands. You can only use a docker task to build the dockfile.

Or you can modify your dockerfile to only have the last copy step to copy the published files from output folder of the dotnet publish task(remove the dotnet restore, build, publish steps from dockerfile), for your dotnet tasks already did the retore build and publish tasks.
