Get in depth with one serialization setting that prevents problems when serializing Entity Framework entities with navigation properties.
- [Lecturer] We've seen in theory…why the reference loop handling setting is so important,…so now let's look at an example of it in code.…To start we'll add a couple of navigation properties…between our tour and reservation entities.…Here in the reservation entity, let's add…a public tour property called tour.…And, in the tour entity, let's add a public property…which is a list of reservation, called reservations.…
Now we should be able to load these navigation properties…up in our queries.…Back in the context class for Entity Framework,…I wanted to point out that as we discussed earlier,…I've disabled lazy loading so that the navigation…properties that we just added,…won't be loaded automatically under any circumstances.…Now if we go to the reservation controllers,…get all method, and we can add and include here,…and we can tell it we want to include…all the tour for the reservations.…
Now let's go test that in Postman.…When we submit a request to the get all method…in the reservations controller,…you can now see that we get an error back that says,…
