+description: Connect your .NET application to a Redis database
+linkTitle: C#/.NET
+title: C#/.NET guide
+weight: 2
+---
+
+[NRedisStack](https://github.com/redis/NRedisStack) is the .NET client for Redis.
+The sections below explain how to install `NRedisStack` and connect your application
+to a Redis database.
+
+`NRedisStack` requires a running Redis or [Redis Stack]({{< relref "/operate/oss_and_stack/install/install-stack/" >}}) server. See [Getting started]({{< relref "/operate/oss_and_stack/install/" >}}) for Redis installation instructions.
+
+You can also access Redis with an object-mapping client interface. See
+[Redis OM for .NET]({{< relref "/integrate/redisom-for-net" >}})
+for more information.
+
+## Install
+
+Using the `dotnet` CLI, run:
+
+```bash
+dotnet add package NRedisStack
+```
+
+## Connect and test
+
+Connect to localhost on port 6379.
+
+```csharp
+using NRedisStack;
+using NRedisStack.RedisStackCommands;
+using StackExchange.Redis;
+//...
+ConnectionMultiplexer redis = ConnectionMultiplexer.Connect("localhost");
+IDatabase db = redis.GetDatabase();
+```
+
+You can test the connection by storing and retrieving a simple string.
+
+```csharp
+db.StringSet("foo", "bar");
+Console.WriteLine(db.StringGet("foo")); // prints bar
+```
+
+Store and retrieve a HashMap.
+
+```csharp
+var hash = new HashEntry[] { 
+    new HashEntry("name", "John"), 
+    new HashEntry("surname", "Smith"),
+    new HashEntry("company", "Redis"),
+    new HashEntry("age", "29"),
+    };
+db.HashSet("user-session:123", hash);
+
+var hashFields = db.HashGetAll("user-session:123");
+Console.WriteLine(String.Join("; ", hashFields));
+// Prints: 
+// name: John; surname: Smith; company: Redis; age: 29
+```
+## Redis Stack modules
+
+To access Redis Stack capabilities, use the appropriate interface like this:
+
+```
+IBloomCommands bf = db.BF();
+ICuckooCommands cf = db.CF();
+ICmsCommands cms = db.CMS();
+IGraphCommands graph = db.GRAPH();
+ITopKCommands topk = db.TOPK();
+ITdigestCommands tdigest = db.TDIGEST();
+ISearchCommands ft = db.FT();
+IJsonCommands json = db.JSON();
+ITimeSeriesCommands ts = db.TS();
+```
