+# Distributed Lock
+Distributed locks are very useful to manage many processes that request the same object. 
+They are used to handle conflict between these requests. Once obtaining anyone it, the others need to wait till give up free.
+
+# Providers
+`MedallionAbpDistributedLock`
+Distributed locks system provides an abstraction that can be implemented by any vendor/provider.
+ABP depends on [DistributedLock.Core](https://www.nuget.org/packages/DistributedLock.Core) library which provides a distributed locking system for concurrency control in a distributed environment. There are [many distributed lock providers](https://github.com/madelson/DistributedLock#implementations) including Redis, SqlServer and ZooKeeper. You may use the one you want. Here, I will show the Redis provider.
+
+This provider contains a method named TryAcquireAsync and this method returns null if the lock could not be handled.
+> Name is a mandatory field. It keeps the locked provider name.
+> Timeout is set as default. If it fells deadlock and doesn't work properly you can use define the time to kill it.
+>CancellationToken is set as default. It enables cooperative cancellation between threads, thread pool work items, or Task objects
+
+
+Also, you should add [DistributedLock.Redis](https://www.nuget.org/packages/DistributedLock.Redis) NuGet package to your project, then add the following code into the ConfigureService method of your ABP module class.
+
+````csharp
+using Medallion.Threading;
+using Medallion.Threading.Redis;
+namespace AbpDemo
+{
+	public class MyModule : AbpModule
+	{
+		public override void ConfigureServices(ServiceConfigurationContext context)
+		{
+			//the other configurations
+			var configuration = context.Services.GetConfiguration();
+			
+			context.Services.AddSingleton<IDistributedLockProvider>(sp =>
+			{
+				var connection = ConnectionMultiplexer.Connect(configuration["Redis:Configuration"]);
+				return new RedisDistributedSynchronizationProvider(connection.GetDatabase());
+			});
+		}
+	}
+}
+````
+
+Also, you should add your Redis configuration in appsetting.json
+````json
+"Redis": {
+    "Configuration": "127.0.0.1"
+}
+````
+
+> To use in APB, you should download the below NuGet package.
+It already contains DistributedLocking.Abstractions  and no need to download as well.
+````powershell
+Install-Package Volo.Abp.DistributedLocking -Version 5.1.4 
+````
+
+````csharp
+using Volo.Abp.DistributedLocking; 
+namespace AbpDemo
+{
+    public class MyService : ITransientDependency
+    {
+        private readonly IAbpDistributedLock _distributedLock;
+		public MyService(IAbpDistributedLock distributedLock)
+        {
+            _distributedLock = distributedLock;
+        }
+
+        await using (var handle = await _distributedLock.TryAcquireAsync("NameOfLock"))
+        {
+            if (handle != null)
+            {
+                //your code
+            }
+        }
+````
