The 10-Day .Net Aspire Challenge – Day 6: Redis Cache

The.Net Aspire framework is used to develop cloud and production-ready distributed applications. It consists of components to handle cloud-native concerns such as Redis, Postgres etc. The HTML or any static content can be cached as well in a web app or a Blazer app. The solution structure is divided into the following projects: DotnetAspireChallenge.Web, Dotnet aspire.AppHost and Dotnet Aspire.Web.

Step-by-step guide on how to use the .Net Aspire Redis Cache component in Visual Studio.

Introduction

.Net Aspire framework is used to develop cloud and production-ready distributed applications. It consists of components to handle cloud-native concerns, such as Redis, Postgres, etc.

Prerequisites

Objectives

Learn how to create a starter project using .Net Aspire with the Redis Cache.

Github Sample: The solution structure is divided into the following projects

  • DotnetAspireChallenge.ApiService
  • DotnetAspireChallenge.AppHost
  • DotnetAspireChallenge.ServiceDefaults
  • DotnetAspireChallenge.Web

Getting Started

Step 1: Install the following NuGet package

Install the following Nuget package into the subsequent project “DotnetAspireChallenge.AppHost”

dotnet add package Aspire.Hosting.Oracle

In the above project, register a server database and consume the Oracle connection using the following code.

```csharp
var cache = builder.AddRedis("cache");

builder.AddProject<Projects.DotnetAspireChallenge_Web>("webfrontend")
    .WithExternalHttpEndpoints()
    .WithReference(cache);

### Step 2: Install another NuGet package

Install the following Nuget package into the subsequent project “**DotnetAspireChallenge.ApiService**”

dotnet add package Aspire.StackExchange.Redis.DistributedCache

then register the context into the Program.cs file as follows

csharp builder.AddRedisDistributedCache("cache");

To add additional connection string properties using the JSON syntax

json { "Aspire": { "StackExchange": { "Redis": { "ConfigurationOptions": { "ConnectTimeout": 5000, "ConnectRetry": 3 } } } } }

Congratulations..!! You’ve successfully integrated the Redis Cache component into the .Net Aspire project.

### Output Cache

The HTML or any static content can be cached as well in a web app or a Blazer app.

csharp // Add the output cache builder.AddRedisOutputCache();

// Build the app
var app = builder.Build();

// Add the middleware
app.UseOutputCache();

To cache a razor page, use the “OutputCache” attribute as follows

csharp @page "/" @attribute [OutputCache(Duration = 10)]

If your project requires to cache the response of APIs, you can use the same “OutputCache” attribute as follows

csharp app.MapGet("/products/{ProdId}", (int ProdId) => $"The product ID is {ProdId}.").CacheOutput(); app.MapGet("/products/{ProdId}", [OutputCache] (int ProdId) => $"The product ID is {ProdId}."); ```
