Xamarin Android AOT Compilation Availability in AzureDevOps - azure-devops

The documentation around the AOT compilation feature of Xamarin Android states that it is only available when using Enterprise additions of Visual Studio. What does this means for AzureDevops build pipelines if the feature is enabled?
Presumably the build agents don't use an Enterprise addition of the Visual Studio build tools so does this mean a build produced via AzureDevops cannot have the AOT feature enabled? If this is true the feature seems of limited use when using AzureDevops as you won't be able to have it enabled for release builds coming from your build pipelines.

The Build Agent "Windows latest" does have VS 2019 Enterprise installed. See here for a link to the List with all included software.
In addition, last time I tried that out I had to manually install the Android NDK. I used a command line step with this:
C:\"Program Files (x86)"\Android\android-sdk\tools\bin\sdkmanager "ndk-bundle"
Although it might well be that this changed meanwhile since it is listed in the included software.

Azure DevOps: What do I need to build .Net 6 solutions?

We have an on-premises Azure DevOps 2019 server, with build pipelines for numerous .Net 4.x solutions that our small team maintains using VS2019.
The team is about to upgrade to VS2022, and at some point I would like to migrate some solutions to .Net 6. Can DevOps 2019 build .Net 6 solutions, and if so what changes are needed to support this (such as presumably installing VS2022 on the server)?
Will those solutions' build pipelines require any changes or should they continue to work as-is? They don't contain anything too clever, with steps such as: NuGet restore, build solution, run unit tests, NuGet pack & push. (The build pipelines are managed via the web GUI, not YAML, if that makes a difference).
Some solutions will remain .Net 4.x, so the server will still need to support (build) these.
You should just need two things:
First you have to install the corresponding SDK for building the apps (see sdk download - Build apps - SDK) on your build-agents.
(Optional) Add or modify your set SDK Task in your pipelines (see use dotnet core task).
One more hint, you don't need to install a whole VS on the server. The Build-Tools are enough (VS2022 Buildtools preview).

How to get VS build agent capabilities without installing the full Visual Studio application?

I've installed the latest VS Build Tools (2022), but my on-prem build agent isn't picking up the VisualStudio-related capabilities. I've been under the impression that we no longer need to install the full application in order to get these capabilities.
An example from this blog post:
I've added all workloads to my offline layout, and I've included them in my installation.
I know this is possible, because earlier I accidentally included Python and VS 2019 Build Tools in my Node.js installation configuration. The VS-related capabilities were found by the agent then.
But I'm trying to get 2022, so I uninstalled 2019.
How can I get the 2022 VS-related capabilities to be installed and detected by my build agent, without installing the full Visual Studio product?
You need to upgrade the agent to a recent enough version. You can download the agent from the azure-pipelines-agent repository's releases page. Or manually specify the capabilities.
You may need to set a special environment flag on the agent to prevent it from automatically being downgraded to whatever version shipped with your version if Azure DevOps Server or Team Foundation Server.
And then you'll also need to install the latest version of the vsbuild/msbuild and vstest tasks
Required agent version
You will need to install the most recent agent from the azure-pipelines-agent repository for it to auto-detect Visual Studio 2022, or alternatively add the capabilities to the agent manually.
You may need to force Azure DevOps Server to not downgrade back to its preferred agent version. You can do so by setting the following environment variable at the system level on your server before launching the agent:
AZP_AGENT_DOWNGRADE_DISABLED=true
These tricks will work for most tasks in the azure-pipelines-tasks repository, as long as it doesn't depend on a UI extension or service connection type that isn't available in your version of Azure DevOps Server.

How to fulfil Visual Studio demand for self-hosted docker build agent?

I've successfully setup and run a self hosted docker build agent using the instructions here: https://learn.microsoft.com/en-us/azure/devops/pipelines/agents/docker?view=azure-devops however VS builds won't run on that agent because it doesn't fulfil a demand for Visual Studio. So my question is
How do install Visual Studio in the docker build agent?
However I've got a feeling this is the wrong question as the project can be build from the command line using dotnet, so an alternative question might be
How to I remove this demand for VS from my build pipeline?
I can't see as I've declared this demand anywhere in the YAML.
How do install Visual Studio in the docker build agent?
For this issue, you can install Visual Studio Build Tools in docker file and then use the built image in the container.
For details, please refer to this official document.

I can't get Nuget push command to work on Visual Studio Online using latest Nuget tasks

I am using Visual Studio 2017 and Visual Studio Online. My team has recently switched to Asp.Net core 1.1 for our web development. Before we had a working nuget publishing process, but that doesn't work anymore because the old nuget tasks are deprecated.
I'm already aware that there should be Nuget package task before the push task, but that task has a known bug for .Net core. Instead I set up my project in VS so that the build task generates my .nupkg file.
Here is my setup from vs-online:
My setup for Nuget push task
The result looks like this:
The result when running.
I solved my problem myself.
I changed the path to:
**/*.nupkg;-:**/packages/**/*.nupkg;-:**/*.symbols.nupkg

CI Build Error with Visual Studio Test step after .Net 4.6 upgrade - Executor process exited; There was no endpoint listening at net.pipe

I just upgraded all of the projects in my solution to point to .Net 4.6 (There is a web app, some class libraries, a database project, etc.). I have a CI build set up in Visual Studio Team Services (using the new build system, not XAML) which was building successfully prior to the upgrade. This build definition runs Debug, Staging, and Production builds and the build definition is comprised of two steps:
Visual Studio Build
Visual Studio Test
Prior to this framework upgrade, everything was building fine. I upgraded and built everything locally and it all worked great too. I could run the tests and got green across the board. Now, when I checked my code in it kicked off the CI build, and I got the following error/s on the "Visual Studio Test" step (taken from the logs):

The Visual Studio Build passes for all three configurations, and the Test step only fails for Debug because it cannot find any tests for the other two configurations. Additionally, my builds are running off of an Azure VM that I stood up to act as a build server, and when I run the CI build using the Hosted build controller the Test step passes, because it cannot find any tests to execute, but the warning about using 'Isolation mode to run tests...' is still printed out in the log.
Is this a known issue? Has anyone else encountered this after a 4.6 upgrade or in another context in VSTS?
Edit: the .Net Framework 4.6 SDK and targeting pack/s ARE installed on the build machine:
The first warning suggests that the tests are running on .NET 3.5:Warning: ... effective Platform:X86 and .Net Framework:Framework35 ...
So I explicitly set the vstest.console framework version to 4.5. (At this time 4.6 is not an available option). That resolved these symptoms for me.
To do so edit the Visual Studio Test build step. On the Build tab of the step settings, expand the Advanced section, and set Other console options to /Framework:Framework45.
I found a workaround for the time being that works for now. I modified the settings for the Visual Studio Test build step as follows:
On the Build tab of the step settings, expand the "Advanced" section, and change the VSTest version to "Visual Studio 2013".
That's all it took for me. I tried this because my build was working when I switched to the Hosted build controller, and this was one of the differences between the two in the logs. This is the only thing that I changed, and it worked. I have no idea WHY the Visual Studio 2015 VSTest version doesn't work, but will look into it more and add to this if I find anything...
I experienced this error (specifically the VSTest exit code) after upgrading a test project to 4.6.1. The issue was that the packages.config didn't update the test framework runner pacakge correctly leaving it at .Net 3.5. Updating the target framework resolved the problem.
After installing .Net Framework 3.5 feature everything was OK! See "cottsay" comment at https://github.com/Microsoft/vsts-tasks/issues/572
