Avalonia projects and test different functions.

These projects were developed as part of the learning process for Avalonia and PostgreSQL.

Projects

• CRUD: This project focuses on basic CRUD (Create, Read, Update, Delete) operations using Avalonia and PostgreSQL.
• ChitChat: ChitChat is a project showcasing chat functionality developed with Avalonia and PostgreSQL. This system is designed to support the transmission of messages between individual employees and groups of employees.
• Hospital: Hospital provides a comprehensive view of hospital wards, allowing you to efficiently manage patient occupancy. With our intuitive drag-and-drop feature, you can seamlessly move patients between words (drag&drop).
• Statistic: This project aims to implement various charts using Live Charts 2, a powerful charting library for .NET applications.
• TestApi: This API is designed for CRUD operations. Data transmission occurs via the request body.
• Usb device driver: using System.IO.Ports in Avalonia. Feel free to explore each project for more details and contributions.

To connect our PostgreSQL database to an Avalonia project

We need to install the following packages in the Avalonia project:

Microsoft.EntityFrameworkCore.Design

To install Microsoft.EntityFrameworkCore.Design package using .NET CLI, run the following command:

dotnet add package Microsoft.EntityFrameworkCore.Design --version 9.0.0-preview.2.24128.4

To install Microsoft.EntityFrameworkCore.Design package using Package Manager, run the following command:

NuGet\Install-Package Microsoft.EntityFrameworkCore.Design -Version 9.0.0-preview.2.24128.4

Npgsql.EntityFrameworkCore.PostgreSQL

To install Npgsql.EntityFrameworkCore.PostgreSQL package using .NET CLI, run the following command:

dotnet add package Npgsql.EntityFrameworkCore.PostgreSQL --version 9.0.0-preview.1

To install Npgsql.EntityFrameworkCore.PostgreSQL package using Package Manager, run the following command:

NuGet\Install-Package Npgsql.EntityFrameworkCore.PostgreSQL -Version 9.0.0-preview.1

This command is used for reverse engineering PostgreSQL databases and automatically generating model classes based on the existing database schema.

dotnet ef dbcontext scaffold "Host=0.0.0.0;Username=postgres;Password=password;Database=DataBaseName" Npgsql.EntityFrameworkCore.PostgreSQL --output-dir <Folder where you want to generate classes>

To overwrite existing classes, use the --force option.

dotnet ef dbcontext scaffold "Host=0.0.0.0;Username=postgres;Password=password;Database=DataBaseName" Npgsql.EntityFrameworkCore.PostgreSQL --output-dir <Folder where you want to generate classes> --force

dotnet tool install --global dotnet-ef --version 7.*
