Have successfully created my TFS2012 XAML builds in TFS2015. This is for a compiled ASP.NET web application and the XAML build output is the entire site folders, compiled DLL, support DLLs etc - the same result as if you do Publish by right-clicking on the project.
Thought I would have a look at how the new VSO build compared so used the Visual studio build template, passed the publishing profile as /P:... and created a drop folder.
The build runs "successfully" but produces no output. The source is copied into the directory on the build machine but the logs show no evidence of the web.config transformation and does not seem to generate any artifacts for copying despite the build reporting "success"....I am sure I am missing something very basic...
