You can notice one thing that it has created a new file “project.lock.json”. You can also find the same in the log of “dnu restore”



In NuGet v3 all packages are downloaded only once to a user level packages directory. The project.lock.json provides the package information to the build system to allow it to only pick packages from the global location that are relevant for the project it is building.

It stores the list of files and relevant content for compilation and runtime so that the build system only has to read a single file instead of many nuspec files.

dnu build

Now run “dnu build”
D:\VSCode\ASPNET5FirstWebAppWithVSCode>dnu build
