The input was not valid .Net Core Web API
Don’t use FromBody. You’re submitting as x-www-form-urlencoded (i.e. standard HTML form post). The FromBody attribute is for JSON/XML.

You would need to either explicitly add the context to the service collection Startup services.AddScoped<DbContext, SchoolContext>(); services.AddScoped<IStudentService, StudentService>(); Or update the StudentService constructor to explicitly expect a type the container knows how to resolve.

Json Format for a TimeSpan that can be bound using Microsoft.Extensions.Configuration
Timespan format in .net core is D.HH:mm:nn (so “1.02:03:04” is 1 day, 2 hours, 3 mins, 4 seconds). javascript wont be able to read that (we use a custom JsonConverter for timespan objects for that reason), but .Net can. {“timespan”:”1.02:03:04″}
