Since a while I discovered some of my buildagent doesn't have the necessary capabilities anymore to build a .NET Framwork web application. When I installed these build agents a few months ago it worked perfect. For some misterious reasons these capabilities went away. Since a week we have VS2017 installed on that machine. A reboot of the machine where the build agent is running doesn't help. Even we rebooted the Team Foundation Server machine. Can any help me with this problem?
