ASP.net. services.AddTransient();

Question

services.AddTransient<JsonFileChampService>();

Does anyone know what the the less than and greater than symbols do after the method name but before the ()?

JsonFileChampService is a .cs file.

In general, what does the '< >' do in C#/.Net/ ASP.net?

Thank you!

Besides `JsonFileChampService` being a cs file, it is also a class that is used to initialize the transient method via AddTransient method of `Type` `JsonFileChampService`. [Read here for Transient method](https://stackoverflow.com/a/38139500/1390548) — Jawad, Jun 29 '20 at 01:08
Search online for `c# generics`. Plenty of documentation to find on it — NotFound, Jun 29 '20 at 07:44

'<>' symbol defines a type.

For example you want to initialise a list of integers:

var listInt = new List();

Or a list of an object: var listObj = new List();

So it defines that the list we are initialising has integers or objects. As for your sample attached it defines that you add a service of type JsonFileChampService.

ASP.net. services.AddTransient();
