Because Azure AppServices doesn't (anymore) support .NET Core 2.1 on x64 with framework-dependent deployments, we are currently publishing self-contained win-x64 versions of our .NET Core 2.1 Web API.

I'm trying to setup an Azure Pipeline in Yaml for CI/CD purposes and deploy it to Azure App Service deployment slot.

The issue I'm trying to resolve is this error-message: **project.assets.json' doesn't have a target for 'netcoreapp2.1/win10-x64'**

```
/usr/bin/dotnet publish /home/vsts/work/1/s/MyApp.WebApi/MyApp.WebApi.csproj --configuration Release -f netcoreapp2.1 -r win10-x64 --self-contained true --no-restore --output /home/vsts/work/1/a/MyApp.WebApi

```

This is my yaml file:

```
# ASP.NET Core
# Build and test ASP.NET Core projects targeting .NET Core.
# Add steps that run tests, create a NuGet package, deploy, and more:
# https://learn.microsoft.com/azure/devops/pipelines/languages/dotnet-core

trigger:

pool:
  vmImage: 'ubuntu-20.04'

variables:
  buildConfiguration: 'Release'
  buildPlatform: x64

  inputs:
    command: 'restore'

    nugetConfigPath: './NuGet.config'
    externalFeedCredentials: 'Hangfire Pro'

- task: PublishBuildArtifacts@1
  inputs:
    pathtoPublish: '$(Build.ArtifactStagingDirectory)' 
    artifactName: 'MyAppWebApi'

```

I tried modifying the CSPROJ file by adding these:

```
<PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    **<RuntimeIdentifiers>win10-x64;win-x64</RuntimeIdentifiers>**

and

<PlatformTarget>x64</PlatformTarget>

```
