Using VS2019 with TFS2018 vnext build system - azure-pipelines-build-task

Does anybody know if it is possible to use VS2019 with TFS2018 vnext build system.
You cannot select VS2019 in the build definition, but you can select "Latest" as version for Visual Studio.
Unfortunately, this does not select VS2019.
I have tested this in a virtual machine with VS2017 and VS2019 installed.
I also upgraded TFS2018 to Azure DevOps Server 2019, which solved the problem.
But this is not a "quick" solution for our production environment.
Here are the logs from my tests. As you can see, selecting "Latest" as version for Visual Studio ended in and error, that no VS was selected at all:

It's not an easy fix. The changes required were pretty extensive.
Officially, the built-in tasks are only upgraded when you upgrade the server to it's next Update version or Major version. TFS 2018 update 3.2 is the latest update version for TFS 2018 and given that Azure DevOps Server 2019 (the new name for TFS) has just been released, I expect that no new versions of the tasks will ship for TFS 2018 update 4 should it ever see the light.
Workaround
CAUTION this may cause issues when upgrading to another server version at a later stage, may require newer versions of the Azure Pipelines Agent and can put you in an unsupported state.
You can clone the Azure Pipelines Tasks repo, build it locally and then use tfx-cli to upgrade the built-in tasks in your server.
git clone https://github.com/Microsoft/azure-pipelines-tasks.git
cd azure-pipelines-tasks
npm install
npm run-script build --task MSBuildV1
npm run-script build --task VstestV2
npm run-script build --task VSBuildV1
npm install tfx-cli#latest -g
tfx build tasks upload --task-path .\MSBuildV2 --service-url {{https://server/tfs/collection}}
tfx build tasks upload --task-path .\VsTestV2 --service-url {{https://server/tfs/collection}}
tfx build tasks upload --task-path .\VsBuildV1 --service-url {{https://server/tfs/collection}}
Repeat for every Project Collection on your server.

I am trying to upload my JS app into Azure DevOps and during the running pipeline, I'm getting an error on the NPM build stage. ##[warning]Couldn't find a debug log in the cache or working directory. I believe this is the reason why NPM build is failing,

Azure file copy Task - [error]Object reference not set to an instance of an object

Within Azure DevOps I have a release pipeline that uses the Azure file copy # version 2.154.19 to copy some files to blob storage.
Recently, the task started to fail with the following error in the logs:
2020-02-03T11:15:33.0304141Z ##[error]Object reference not set to an instance of an object.
The full task logs from Azure DevOps are as follows

Is there any better debugging that I can enable for Azure DevOps tasks?

Hey Kevin if you want to get debug information in a release definition create a variable system.debug and set it to true. I just took a look at github and there is an open issue with the same error message for the v2 version of the task.
I would run it with debug, to see if its the same issue and then try the v3 version of the task.

VSTS Azure App Service Deploy release task doesn't update files

In my release definition, I have a step to deploy Azure web app service.
The step is finished without any errors, however, the application files inside the wwroot folder aren't changed.
Below are the logs for this step:

After clean, the deploy is performed correctly.
I am wondering why application redeploy (update) doesn't change the necessary files.

Please try with the Azure App Service Deploy task with 4.* (preview) version, and select your App Service type correspondingly.

Cannot index into a null array.

BTW I've noticed that the hosted agents were updated recently (2/7/2017), I'm wondering if that could be related to this issue?

Not sure what happened but I was able to fix the problem.
I have deleted the Azure Service Fabric endpoint and created a new one (Certificate Based), with the correct Thumbprint, Client Certificate, Password etc.

The below PowerShell scripts help in converting the PFX file to Base64 string. It outputs the string to a text file.
$fileContentBytes = get-content 'C:\<your-certificate>.pfx' -Encoding Byte
[System.Convert]::ToBase64String($fileContentBytes) | Out-File 'C:\pfx-bytes.txt'
However, when you open the file (that contains Base64 string) in notepad and do a select all (CTRL + A) operation, an extra line (break) at the end of the file gets copied. This extra line gets pasted while adding the Client certificate during the creation of Cluster Service Connection for the task Service Fabric Application Deployment.
Delete that extra line and it should work. I hope this answer helps as well.

I think the problem here could be that you are using the Base64 of the cer certificate file on the SF endpoint, rather than Base64 of the PFX file (which is normally protected by a password).
