Project code structure:

II. Third-party Dependencies

Common dependencies

1. log4net logging.
2. SignalR for communication between server and client; used for friend requests, message notifications, announcements, chat, and audio/video calls.
3. EntityFrameworkCore ORM for database operations; server uses SqlServer, client uses Sqlite.
4. Newtonsoft.Json for JSON serialization and deserialization.

Server side

1. TencentCloudSDK to interact with Tencent Cloud service APIs, used for managing call rooms.
2. aliyun-net-sdk-core to interact with Alibaba Cloud service APIs, used for SMS services.
3. CHSPinYinConv to obtain Chinese pinyin.
4. Portable.BouncyCastle for TRTC encryption.
5. SixLabors.ImageSharp for image processing; because image processing in C# requires GDI from Microsoft, but on Linux it requires the mono libgdiplus library, which is not ideal.

WPF client

1. TXLiteAV to interact with Tencent Cloud TRTC service for local device audio/video streaming and obtaining audio/video data from other users in the room.
2. XamlAnimatedGif for playing GIFs; due to device efficiency issues, the author modified the source code and repackaged it for use.

III. Project Configuration

To run this project properly, please understand the related configuration.

3.1 Backend Configuration:

The backend is developed with .NET Core Web API. Configuration is as follows:

1. Third-party service configuration

Modify the ClassHelper class under the DimensionService.Common namespace.

Please fill in the paid services marked in the red box. This program uses Alibaba Cloud's SMS service and Tencent Cloud's TRTC service. Refer to official documentation for details.

2. Database

This service uses SQL Server 2019 as the database and EF Core as the primary ORM framework. The database needs to be migrated for first-time use.

Open the Package Manager Console and enter:

Update-Database InitialCreate

The project provides an online test service address: http://47.96.133.119:5000 (Note from site admin: this address is currently inaccessible)

3.2 Client Configuration

The client is developed with WPF as shown below:

The content in the red box must be consistent with the server side.

IV. Feature Demo

The author is too lazy to write more details now!

I will provide test accounts and program addresses.

But first, you need to install .NET 6 desktop runtime. Here is the download link: .NET 6 Desktop Runtime
