On 14. August 2017 ASP.NET Core 2.0 was released by Microsoft. Why is this relevant to SEO? Well, ASP.NET Core 2.0 is much faster than the previous version. And performance matters, especially when it comes to SEO.
A big improvement is the warm up of an ASP.NET Core 2.0 web application. As the razor pages and views are precompiled, an ASP.NET Core 2.0 website will start faster after it gets deployed on the server or to Azure.
