Publish ASP.NET Core to Azure fails unexpectedly -

i have project based on asp.net core 1.0. can build , run locally without problems, if try publish project azure using publish mechanism in visual studio 2015 (even if try publish locally folder in file system or using ftp) fails unexpectedly without giving me concrete message. if run preview log:

    "publish" task failed unexpectedly.     system.exception:      publishing project.web .netframework,version=v4.5.2/win7-x64     @ microsoft.dotnet.tasks.publish.execute()    @ microsoft.build.backend.taskexecutionhost.microsoft.build.backend.itaskexecutionhost.execute()    @ microsoft.build.backend.taskbuilder.<executeinstantiatedtask>d__26.movenext() 

if try publish ignoring error or if not try preview this:

1>------ publish started: project: kunato.web, configuration: debug cpu ------ rmdir /s /q "c:\users\thimo\appdata\local\temp\publishtemp\kunato.web54\" environment variables: dotnet_configure_azure=1 path=.\node_modules\.bin;c:\program files (x86)\microsoft visual studio 14.0\web\external;%path%;c:\program files (x86)\microsoft visual studio 14.0\web\external\git c:\program files\dotnet\dotnet.exe publish "c:\code\git\web_kunato\src\kunato.web" --framework net452 --output "c:\users\thimo\appdata\local\temp\publishtemp\kunato.web54" --configuration debug --no-build publishing kunato.web .netframework,version=v4.5.2/win7-x64  1>publish failed due build errors. check error list more details. ========== build: 0 succeeded, 0 failed, 7 up-to-date, 0 skipped ========== ========== publish: 0 succeeded, 1 failed, 0 skipped ========== 

if requested , @ error list, there no error , looks good. there other log files or check problem might be?
