The Dnx Runtime package needs to be installed

In VS2015 running on Windows 10 x64 machine, I am getting below error while trying to build the .net core web project. 

The Dnx Runtime package needs to be installed. See output window for more details

Here is the output window log (only relevant portion)

Going behind the log, I checked Microsoft.DNX.targets file and found this line 

<Error Text="The Dnx Runtime package needs to be installed. See output window for more details." Condition="!Exists('$(RuntimeToolingExe)')" />

Seems like it is trying to find-out the dnx path from $(RuntimeToolingExe) but I am not able to figure-out where it is being set.

Note: The dnx runtimes are already installed and I am able to run the application from command prompt using following command

dnx web

The application is running fine with this. I believe it is an issue with the VS2015 tooling which I am not able to figure-out. Could you please help me on this?

PS: Followed all the steps provided in this SO thread nothing seems to be working.

Solution

  • The issue finally resolved once I uninstall styleCop. Seems like the StyleCop was overriding the dnx path which Visual Studio was looking for. However, this is just a guess, I am not particularly sure why it worked!
