This package is just RedLock.net wrapper and simplifies it using within NetCore

Usage

Run redis server on you machine first

docker run -d -p 6379:6379 redis

Add ch1seL.DistributedLock.RedisLock to your project

dotnet add package ch1seL.DistributedLock.RedisLock

Register in DI

Host.CreateDefaultBuilder(args)
    .ConfigureServices((hostContext, services) =>
    {
        services.AddStackExchangeRedisLock(options => options.Configuration = "localhost");
    }

Inject and lock some piece of code

public class Worker : BackgroundService
{
    private readonly IDistributedLock _distributedLock;

    public Worker(IDistributedLock distributedLock)
    {
        _distributedLock = distributedLock;
    }
    
    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        using (await _distributedLock.CreateLockAsync("test-lock", cancellationToken: stoppingToken)) {
            await DoSomeStuff();
        }
    }
}

Testing and local usage

For testing or local usage you can register in-memory implementation

dotnet add package ch1seL.DistributedLock.MemoryLock

Host.CreateDefaultBuilder(args)
    .ConfigureServices((hostContext, services) => {
        if (hostContext.HostingEnvironment.IsDevelopment()) {
            services.AddMemoryLock();
        } else {
            services.AddStackExchangeRedisLock(options => options.Configuration = "localhost");    
        }
    }
