I created some reports in Visual Studio 2015 with all the latest updates. However, when I try to deploy the reports I get this message:
The definition
The settings below should be set to your sepecific version of SSRS, and then take the RDL from the \bin directory
Or, after updating the TargetServerVersion, simply use right click | deploy
from the rdl.
The accepted answer is significantly more difficult/prone to error/unlikely to work across multiple versions of ssrs, and needs to be applied each time you change the rdl.
