The asp-net-core
solution demonstrates the use of ASP.NET Core to compose a UI with data from several services.
If the answer to your question is not listed here, consult your on-site trainer.
The simplest method is to delete all databases, which will be automatically created by LiteDb.
The databases are individual files that are located in a .db
folder under the solution folder. The entire folder can be deleted.
The exercises use the LearningTransport and LearningPersistance. Delete the entire .learningtransport
under the solution folder.
You can download LiteDb Studio and open each database individually. The database files are stored in a .db
folder in the root of each exercise its solution folder.
NOTE: If you open a database, open it as 'shared' as otherwise LiteDb Studio will lock the database and your exercises won't work anymore.
Sometimes there are issues in the API. Because of the CompositionGateway it might not be directly clear what the problem is.
- Verify if the different API projects are running in Visual Studio and/or JetBrains Rider
- Divergent.Sales.API
- Divergent.Finance.API
- Divergent.Customers.API
- Divergent.CompositionGateway
- Verify if the response is correct using Postman be sending HTTP requests to the following uri:
- http://localhost:20185/api/orders/ for sales
- http://localhost:20187/api/prices/orders/total?orderIds=1 for finance
- http://localhost:20186/api/customers/byorders?orderIds=1 for customers
- http://localhost:4457/orders/ for the Composition Gateway
