These are the steps I did for .NET 5 deployment in Azure DevOps.

  1. Created Azure Web App with .NET 5 (Early Access) enter image description here
  2. Created Pipeline in Azure DevOps enter image description here
  3. Created Artifact from new release pipeline enter image description here
  4. Selected Azure App Service deployment template enter image description here
  5. Selected Dev stage enter image description here
  6. Run on agent settings enter image description here
  7. Azure App Service Deployment Settings enter image description here
  8. Created a new release enter image description here
  9. Received error enter image description here 10 ) Error in detail enter image description here

This is the problem that I'm facing right now. Anybody has an idea how to resolve ?

The App Service Deploy task is only capable of deploying a single ZIP file at a time. It probably is detecting a duplicate (although it's possible it's something else). Your deployment path, $(System.DefaultWorkingDirectory)/**/*.zip, makes it convenient to pick up your build package and deploy it, but only if there's one.

You need to change that property to specify the single ZIP you want to deploy. It's ok to leave the ** in the path so long as the rest of the name resolves to a single file. You may want to go back to your last build run result, click on the Artifact that was published, and then inspect the contents to determine correct path and name.

The task Azure App Service deploy field Package or folder means File path to the package or a folder containing app service contents generated by MSBuild or a compressed zip or war file.

enter image description here

The field default value is $(System.DefaultWorkingDirectory)/**/*.zip, it will match all zip file in the path $(System.DefaultWorkingDirectory) and If the number of zip files exceeds one, we will receive the error message: Error: More than one package matched with specified pattern: D:\a\r1\a\**\*.zip. Please restrain the search pattern.

We could specify the zip file for deployment, check the pic below:

Then it should work.

  • Thanks for sharing, as per your instruction I have configured, now it has been working fine. – Parthiban Jun 15 '21 at 07:57
  • Out of interest how would I change this in YML? I have the task and I tried to add a website folder instead of **/*/.zip, but then got an error that said, Website does not exist. – Jason Nov 08 '21 at 10:32

If you visit the previous step of the release plan, you will be able to see zip files Azure found. It looks like there ismore than 1 .zip file. You just need to narrow your filter.
