I haven't used Visual Studio ('17) for a while, but recently I've attempted to create an ASP.NET application and received the following error in the form of a dialog. I've also noticed that the option: ASP.NET Web Application has been replaced.
Error: this template attempted to load component assembly 'Microsoft.VisualStudio.Web.Project, Version[equalstosign]2.3.0.0, Culture[equalstosign]neutral, PublicKeyToken[equalstosign]b03f5f7f11d50a30a'.For more information on this problem and how to enable this template, please see documentation on customizing project templates.
