We recently migrated from TFS 2013 to Azure Devops 2019 ( on premises ) We have two servers , TFS server is running Azure DevOps 2019 and build controller is running on TFS 2010 As a result , Older XAML build are working fine.
We recently upgraded .net framework on app servers to 4.8 from earlier v 4.5
We want to use latest C# features , but not able to build those on build server.
For this , We want to use tfvctemplate.12.xaml build template which has support for C#-6 language features.
But after changing default.xaml build template to above build tfvctemplate.12.xaml template , and after queuing the builds getting below error.
TF900558: This build process template cannot be run on build server Default Controller - TFSBUILDSVR3. Upgrade this build server to a newer version.
We installed Azure Devops 2019 on build controller but could not configure build controller like we did it for TFS 2010.
Any help is appreciated !
XAML builds are deprecated for TFS 2018 and later versions. If you want to use TFS2019, you need to migrate to the new builds.
This document details the process of deprecating the old build and becoming familiar with the new builds.
Xaml builds are working in our Azure DevOps 2019 , but when we try to use a different template "tfvctemplate.12.xaml" , it shows error. ( This template is required to build C#6 code. ). I think we have two options here 1) Migrate from XAML to YAML 2) Upgrade TFS version on Build controller server from 2010 to 2018 ( as 2018 is the last version to support XAML builds ) Question : Is there any concept of Build controller in Azure devops like earlier TFS version ?
@sagar I suggest you upgrade TFS version on Build Controller Server to TFS2013 or TFS2015. Because document shows that
tfvctemplate.12.xamlapplies to the two versions. For instructions on how to set up build Controller, refer to these two documents, document 1 and document 2.@sagar As far as I know, Azure DevOps Server 2019 cannot set up build controller. You need to have two servers. Azure DevOps Server 2019 and TFS 2013/2015 to config build controller.
