.NET Core 2.1 ConfigurationBuilder.Build() - StackOverflowException

Question

I've installed VS 2017 Preview and 2.1.300-preview2-008530 SDK. Now, in my Web Application project following sequence generates StackOverflowException:

var builder = new ConfigurationBuilder()
                            .SetBasePath(env.ContentRootPath)
                            .AddJsonFile("appsettings.json");

NET Core 2.1 Preview 2 Known Issues - does not contain anything related to my problem.

Answer 1

Add this package Microsoft.Extensions.Configuration.json

I ran into the same issue after upgrading to 2.1 and found this answer on microsoft online doc
