On this page of ReSharper options, you can configure ReSharper's NuGet package restorer.
ReSharper also provides its own implementation of NuGet restorer, which works with all Visual Studio versions. By default, ReSharper makes sure that all related NuGet packages are restored before each build, but you can disable it by clearing the corresponding check-box on the Tools | Build | General page of ReSharper options. If the automatic restore is disabled, you can always run it manually by clicking Restore NuGet packages on the toolbar of Build & Run window.
Log level for writing NuGet package restorer messages to output
If logging to the Output window is enabled on the Tools | Build | General page of ReSharper options, you can use this selector to specify which NuGet restorer messages should be logged.
Click this button to display log messages from NuGet restorer in the current Visual Studio session.
