Quickstart in Couchbase Lite Query in C# with dotnet and Xamarin

Build an cross platform iOS, Android, and UWP App in Xamarin Forms with Couchbase Lite

This repo is designed to show you an app that allows users to log in and make changes to their user profile information. User profile information is persisted as a Document in the local Couchbase Lite Database. When the user logs out and logs back in again, the profile information is loaded from the Database. This app also demostrates how you can bundle, load, and use a prebuilt instance of Couchbase Lite and introduces you to the basics of the QueryBuilder interface.

Full documentation can be found on the Couchbase Developer Portal.

Prerequisites

To run this prebuilt project, you will need:

For iOS development a Mac running MacOS 11 or 12
For iOS Development Xcode 12/13
For Android development SDK version 22 or higher
For UWP development, a Windows computer running Windows 10 1903 or higher
Visual Studio for Mac or PC

Installing Couchbase Lite Framework

The Couchbase Documentation has examples on how to add Couchbase Lite via nuget package.

App Architecture

The sample app follows the MVP pattern, separating the internal data model, from a passive view through a presenter that handles the logic of our application and acts as the conduit between the model and the view

Try it out

Open src/UserProfileDemo.sln using Visual Studio
Build and run the project.
Verify that you see the login screen.

Conclusion

This tutorial walked you through an example of how to use a pre-built Couchbase Lite database and has a simple Query example to show you how to use the QueryBuilder API in dotnet with C# and Xamarin Forms.
