I got this error when try to start Android solution in Xamarin Live Player on VS2017.

"Dependent project xx.csproj failed to build, using old version"

Any clue? Thanks.

  • if you build just the failed project, what does it say? – Jason Dec 18 '17 at 16:47
  • no errors on build – Dracarys Dec 18 '17 at 16:52
  • are you actually looking at the verbose build output? – Jason Dec 18 '17 at 16:56
  • yes, the build complete successfull – Dracarys Dec 18 '17 at 16:57
  • if the dependent project builds, then try re-building the parent project. You may also want to clean it first, or manually delete the bin and obj folders – Jason Dec 18 '17 at 17:13
  • I just installed Xamarin Live Player **16 hours ago** and have the same issue. The first time I used Xamarin Live for the project it worked, but since then it always fails saying "Dependent project xx failed to build" and it uses the old version instead. My changes to project were only one character in the welcome string of the template MainPage. – this.myself Dec 19 '17 at 06:46
  • yes me too. I create a new project and only changed the "hello xamarin" string and have the same problem again. – Dracarys Dec 19 '17 at 07:23
  • maybe it's my impression but I think that message is show for each type of error. I solved it simply ricreate the project and test every time I change some code. So the error is another one and not what the message write, check your code. – Dracarys Dec 19 '17 at 09:44
  • Now tracking this here: https://github.com/xamarin/Xamarin.Forms/issues/1787 with a workaround for today. Will post an update to app soon – JamesMontemagno Feb 05 '18 at 18:54
