Azure DevOps Pipeline PostSharp failure on linux VM

Question

I had planned to move my DevOps Pipeline to linux vm. Unfortunately, I faced with this problem. I am using Postsharp 6 on my .Net Core 2.2 project.

Build FAILED.

/home/vsts/.nuget/packages/postsharp/6.1.18/build/PostSharp.targets(148,5): error MSB4062: The "PostSharp.MSBuild.PostSharpValidateLanguageVersion" task could not be loaded from the assembly /home/vsts/.nuget/packages/postsharp/6.1.18/build//net471/PostSharp.MSBuild.v6.1.18.Release.dll.

PostSharp doesn't work on Linux VM.

The only solution is using Windows Server on yaml. Even Selenium removed Postharp support.

trigger:
- master

pool:
  vmImage: 'windows-2019'

variables:
  buildConfiguration: 'Release'

steps:
- script: dotnet build --configuration $(buildConfiguration)
displayName: 'dotnet build $(buildConfiguration)'

You can look at the pictures to understand the steps better.

• Update

PostSharp 6.3.5 preview version supports Linux and macOS builds.

Also, you can create a docker image too. I am using these images:

FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-stretch-slim AS base
FROM mcr.microsoft.com/dotnet/core/sdk:2.2-stretch AS build
