Overview

This packages implements the Generic Repository pattern for interacting with data in CosmosDB. The goal is to leverage CosmosDB's schemaless capabilities to allow developers to interact only with Plain Old C# Objects (POCOs) and not have to worry about any of the complexity of integrating with CosmosDB. The purpose is to make it easier to deal with 90% of the interaction with CosmosDB. You'll notice that we expose the CosmosDB client out of the repository to allow you to cover the other 10% with your own custom code.

Here is a sample of what using the GenericRepository looks like:

/// A sample POCO that inherits from BaseStorableEntity var item = new TestObject { Collection = new List<string> { "TestVal1", "TestVal2" }, Number = 5, Prop1 = "TestingString", ChildObject = new TestObject { Number = 8, Prop1 = "ChildObject" } }; // Inserting the document into CosmosDB var result = await _testRepo.Upsert(item); // retrieving a document by id var retrieved = await _testRepo.Get(result); // retrieving a document using a predicate (lambda expression) var doc = await _testRepo.FindOne(x => x.Id == result);

The real power of this library is the ability to dynamically query your data using your strongly typed objects.
