I've created a blank solution in VS2019. Using the option "add existing website" I've added a website to the solution which was built in VS2010. Normally, after that, I was used to add a Web Deployment Project to the solution, to compile all the code in one dll, and upload the result to the web server. But this kind of project does not seem to be compatible anymore with the newer versions of VS.
Please advice. TQ

Users of that project type have been recommended to migrate to ASP.NET Web Application project type for years, and now of course ASP.NET Core/Blazor.
