getting error in AzureDevOps Release pipeline running due to artifact

Question

Hello I am having a problem. Suppose I am having a simple web app and pushed it to Azure Repos. Now I set up a build pipeline using yaml and then I set up a release pipeline which will require an artifact from the build pipeline. So I am using PublishPipelineArtifact@1. The build pipeline runs fine but my release pipeline fails with error Deployment of msBuild generated package is not supported. Change package format or use Azure App Service Deploy task. D:\a\r1\a_ReleasePipelines\drop\WebApp.zip. So how to provide artifact required by release pipeline in correct naming sequence?

Below is my yaml for build pipeline

`

# ASP.NET Core (.NET Framework)
# Build and test ASP.NET Core projects targeting the full .NET Framework.
# Add steps that publish symbols, save build artifacts, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/dotnet-core

trigger:
- master

pool:
  vmImage: 'windows-latest'

variables:
  solution: '**/*.sln'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'

steps:
- task: NuGetToolInstaller@1

- task: NuGetCommand@2
  inputs:
    restoreSolution: '$(solution)'

- task: VSBuild@1
  inputs:
    solution: '$(solution)'
    msbuildArgs: '/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:DesktopBuildPackageLocation="$(build.artifactStagingDirectory)\WebApp.zip" /p:DeployIisAppPath="Default Web Site"'
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'

- task: PublishPipelineArtifact@1
  inputs:
    targetPath: '$(build.artifactStagingDirectory)'
    publishLocation: 'pipeline'

` Next I am setting up a simple release pipeline using empty job and there in Add Artifact I am supplying the project name and source.

From the MS build arguments in your YAML, it is for Web Deploy method.

If you would like to change the method to Zip deploy, you could follow this official link to change the Arguments: https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/reference/azure-rm-web-app-deployment-v4?view=azure-pipelines&viewFallbackFrom=azure-devops#error-publish-using-zip-deploy-option-is-not-supported-for-msbuild-package-type

Publish build artifacts is recommended: https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/reference/publish-build-artifacts-v1?view=azure-pipelines&viewFallbackFrom=azure-devops

Here is a sample,

steps:
- task: PublishBuildArtifacts@1
  displayName: 'Publish Artifact: drop'
  inputs:
    PathtoPublish: '$(build.artifactstagingdirectory)'
  condition: succeededOrFailed()

In your release pipeline, you need to specify the pipeline artifacts from build :

And use Azure App Service Deploy task for the deployment.
