Before moving further, we should definitely attempt a quick test run to ensure that everything is working properly. Doing that should be just as easy as hitting the Run button or the F5 key:
This is an excellent consistency check to ensure that our development system is properly configured. If we see the sample Angular SPA up and running, as shown in the preceding screenshot, it means that we're good to go; if we don't, it probably means that we're either missing something or that we've got some conflicting software preventing VS2017 and its external web tools (NPM/NODE) from properly compiling the project.
In order to fix that, we can try to do the following:
- Uninstall/reinstall Node.JS, as we can possibly have an outdated version installed.
- Uninstall/reinstall Visual Studio 2017, as our current installation might be broken or corrupt. The.NET Core SDK should come shipped with it already; however, we can also try reinstalling it.
- Update the SPA templates using the command-line interface by following the instructions we gave in the previous paragraph.
- Install VS2017 on a clean environment (be it either a physical system or a VM) to overcome any possible issue related to our current operating system configuration.
If none of these works, the best thing we can do is to ask for specific support on the .NET Core community forum, at https://forums.asp.net/1255.aspx/1?ASP+NET+Core.
