Multitenancy in asp net core 2 0

Introduction

ASP.NET is a popular programming language used for building web applications. One of the challenges developers face is implementing in ASP.NET Core 2.0. Multitenancy refers to the ability of a single application to serve multiple tenants, where each tenant has its own isolated data and configuration.

Understanding Multitenancy

In a multitenant application, tenants are typically identified by a unique identifier, such as a subdomain or a database schema. Each tenant has its own set of data and configuration, but they all share the same codebase and infrastructure.

Implementing Multitenancy in ASP.NET Core 2.0

ASP.NET Core 2.0 provides built-in support for multitenancy through the use of middleware and dependency injection. Let's take a look at how we can implement multitenancy in ASP.NET Core 2.0.

Step 1: Create a Tenant class

The first step is to create a Tenant class that represents a tenant in our application. This class contain properties to store the tenant's unique identifier, data, and configuration.


 class Tenant
{
    public string Id { get; set; }
    public string Data { get; set; }
    public string Configuration { get; set; }
}

Step 2: Implement a TenantResolver

The next step is to implement a TenantResolver class that will be responsible for resolving the current tenant based on the request. This class should have a method that in the request and returns the tenant.


public class TenantResolver
{
    public Tenant Resolve( )
    {
        //  to resolve the tenant based on the request
    }
}

Step 3: Configure the Multitenancy Middleware

Now, we need to configure the multitenancy middleware in our ASP.NET Core 2.0 application. This middleware will be responsible for resolving the current tenant and setting it in the request context.


public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseMultitenancy();
    // Other middleware 
}

Step 4: the Current Tenant

Once the multitenancy middleware is configured, we can access the current tenant in our controllers or services using dependency injection.


public class MyController : Controller
{
    private readonly Tenant _tenant;

    public MyController(Tenant tenant)
    {
        _tenant = tenant;
    }

    public IActionResult Index()
    {
        // Access the current tenant using _tenant
        return View();
    }
}

Conclusion

Implementing multitenancy in ASP.NET Core 2.0 can be achieved by following these steps. By leveraging the built-in support for multitenancy, developers can easily create applications that serve multiple tenants with isolated data and configuration.
