You will also be able to easily integrate your front-end projects with an ASP.NET Core backend, and even leverage existing tools in Visual Studio like the Test Explorer. When TypeScripts specified module lookup strategy is unable to resolve a path, it will now resolve packages relative to the specified typeRoots. Follow the tutorial here: https://docs.microsoft.com/en-us/visualstudio/javascript/tutorial-asp-net-core-with-vue?view=vs-2022.
