This sample demonstrates the use of custom resources service for GrapeCity ActiveReports Web Designer with an ASP.NET Core backend.

To use custom store for a designer follow these steps:

1. Implement IResourcesService interface. Also you should implement IDisposable interface if you use any unmanaged resources.
2. Implement ResourceLocator for your store. It is required for the correct getting report resources (datasets, themes, images, etc).
3. In GetReport method redefine report site using implemented resourse locator. See CustomStoreReports.cs for more details.
4. In Startup class:
   1. Register your implemented IResourcesService service.
   2. Call UseCustomStore method for viewer (app.UseReporting) with GetReport method as argument.
   3. Call UseCustomStore method for designer (app.UseDesigner) with IResourcesService implementation as argument.

This case contains two different implementations based on the LiteDB and CosmosDB as an example.

LiteDB implementation is used by default. To try CosmosDB implementation, please, follow this guide.
