    I need to install 2020.1.2 version on new hardware. After installing with provided installer I see that my server have version 18.181.32404.7.
    Should I install all patches in sequence, or they are cumulative and I can install only latest Patch #18?

      hi Sergejs
      version is 18.181.32404.7 is effectively 2020.1.2 RTM and you should install latest Patch #18.
      all patches within same version are cumulative and therefore you only need to install #18 but you probably should read the release notes “Azure DevOps Server 2020 Update 1.2 Patch 10 Release Date: November 14, 2023” as they mention to install patch 8 first before install higher version due to build agent updates.

    Given the issues you've linked you've probably seen my Task Zips project and the Compatibility Pack published to the Visual Studio Marketplace.

    In these cases you can set an environment variable to allow Azure DevOps Server to run the latest Azure Pipelines Agent (the one officially built for Cloud). This will fix the capabilities and environment variables

    You can push the build tasks downloaded from Azure DevOps Cloud to your Azure DevOps Server Collection Database using the official tfs-cli (tfx) or by pushing the zip of the task directly to the API.

    Documentation and scripts can be found in the project:

        Hi Gloridel,
        My ticket was closed even though I provided all the necessary information about this issue.
        Thanks for best support.

    hi Gloridal

    why are there some suspect increase in assembly version for:
    Azure DevOps Server 2022.2 Patch 8:
    from 19.235.36624.2 (patch 7) to 19.235.37004.3

    and more suspect:
    Azure DevOps Server Patch 1:
    from 20.0.36719.1 (RTM/GA) to 20.256.37004.2
    where both minor and build version number changed significantly – especially minor is very likely wrong and taken from Azure Devops Server 2022.2 Patch 8 build configuration

      Hello,
      all Azure DevOps Server 2022.2 assemblies have 19.0.0.0 assembly version. Azure DevOps Server has assemblies with version 20.0.0.0.
      You are referring to the file versions. Most binaries in in Azure DevOps Server 25H2 have 20.256.* file versions, but installers have 20.0.* file versions. This is expected.

      Does it cause any issues for you?
      Thanks,
      –Vladimir

    Hey Gloridel,

    Been wanting to switch a few projects over to .NET 10, though a lack of support between the MSBuild and VSBuild tasks are preventing us from moving forward. The last time we tried installing the build tools to our server, the PATH changed, and the VSBuild task could no longer find the build tools. We are going to switch to Azure DevOps Server, though only want to do so once we know the compatibility we need is there. Is there an ETA as to when this will be available, or has .NET 10 and the pipeline task support for...
