🚀 Quick Start

Prerequisites

• .NET 8.0 SDK or later
• Windows OS (for .cmd scripts) or cross-platform support with .NET

Standard Update Demo

1. Clone the repository

   git clone https://github.com/GeneralLibrary/GeneralUpdate-Samples.git
   cd GeneralUpdate-Samples/src

2. Run the standard update demo

   start.cmd

   This script will:

   • Build the Client, Server, and Upgrade projects
   • Copy compiled files to the run directory
   • Start the Server application
   • Start the Client application
   • Automatically trigger the update process

3. Verify the update

   • The Client will detect available updates from the Server
   • Download and apply the update package
   • Restart automatically after update completion
   • Check for the new file Congratulations on the update.txt in the run directory

OSS Update Demo

For a simplified update mechanism without server-side code:

cd src
oss_start.cmd

This demonstrates OSS-based updates using only a version.json configuration file on a file server.

📦 Sample Projects

Client Sample (src/Client)

Demonstrates the main application that requires updating. Key features:

• Version detection and verification
• Update package download with progress tracking
• Event-based notification system
• Automatic restart after update

Key Code:

var configinfo = new Configinfo
{
    UpdateUrl = "http://127.0.0.1:5000/Upgrade/Verification",
    MainAppName = "ClientSample.exe",
    ClientVersion = "1.0.0.0",
    ProductId = "2d974e2a-31e6-4887-9bb1-b4689e98c77a"
};

await new GeneralClientBootstrap()
    .AddListenerMultiDownloadStatistics(OnMultiDownloadStatistics)
    .AddListenerMultiDownloadCompleted(OnMultiDownloadCompleted)
    .AddListenerException(OnException)
    .SetConfig(configinfo)
    .LaunchAsync();

Server Sample (src/Server)

Minimal API server providing update information and package distribution:

• Version verification endpoint
• Update package download endpoint
• Update status reporting

Key Code:

app.MapPost("/Upgrade/Verification", (VerifyDTO request) =>
{
    var result = new List<VerificationResultDTO>
    {
        new VerificationResultDTO
        {
            Version = "1.0.0.1",
            Url = "http://localhost:5000/packages/packet.zip",
            Hash = "...",
            Size = packet.Length
        }
    };
    return HttpResponseDTO<IEnumerable<VerificationResultDTO>>.Success(result);
});

Upgrade Sample (src/Upgrade)

Independent upgrade process that updates the main application:

• Downloads update packages
• Applies updates while main app is closed
• Restarts main application after update
• Provides rollback capability on failure

OSS Update Sample (src/OSS)

Simplified update mechanism:

• No server-side code required
• Uses version.json configuration on file server
• Direct file server integration (Alibaba Cloud OSS, AWS S3, etc.)
• Supports AOT compilation

version.json Example:

[
  {
    "PacketName": "packet_20250102230201638_1.0.0.1",
    "Hash": "ad1a85a9169ca0083ab54ba390e085c56b9059efc3ca8aa1ec9ed857683cc4b1",
    "Version": "1.0.0.1",
    "Url": "http://localhost:5000/packages/packet_20250102230201638_1.0.0.1.zip"
  }
]

Bowl Sample (src/Bowl)

Process crash monitoring and diagnostic information export:

• Monitors main application health
• Captures crash dump files
• Exports system information
• Provides automatic rollback on crash

Exports on Crash:

• 📒 Dump file (.dmp)
• 📒 Version information (.json)
• 📒 Driver information (driverInfo.txt)
• 📒 System information (systeminfo.txt)
• 📒 Event logs (systemlog.evtx)

Diff Sample (src/Diff)

Binary differential update implementation:

• Generates differential patches between versions
• Identifies changed, new, and deleted files
• Supports blacklist for excluded files
• Reduces update package size significantly

Push Sample (src/Push)

Real-time update notification using SignalR:

• Push latest version information to clients
• Immediate update notifications
• Supports forced update triggers
