ASP.NET Core Middleware
Duration : 00:02:00
Static Files Middleware
The Static Files Middleware in ASP.NET Core serves static resources like HTML, CSS, JavaScript, and images, making it easy to include client-side assets in your web application.Example
app.UseStaticFiles();
Error Handling Middleware
Error Handling Middleware helps manage exceptions and provide custom error responses in your application, improving the user experience and simplifying debugging.Example
app.UseExceptionHandler("/Home/Error");
app.UseStatusCodePagesWithReExecute("/Home/Error/{0}");
Authentication Middleware
The Authentication Middleware allows you to implement various authentication schemes, securing your application by verifying user identity.Example
app.UseAuthentication();
app.UseAuthorization();
Session Middleware
Session Middleware enables you to store user-specific data on the server for the duration of a user's session, which is useful for maintaining state between HTTP requests.Example
app.UseSession();
Cookie Policy Middleware
Cookie Policy Middleware lets you configure and enforce policies related to cookies, ensuring proper cookie handling and security.Example
app.UseCookiePolicy(new CookiePolicyOptions
{
MinimumSameSitePolicy = SameSiteMode.Strict,
HttpOnly = HttpOnlyPolicy.Always
});
MVC Middleware
The MVC Middleware integrates the Model-View-Controller pattern, making it easier to create dynamic web applications with clean, structured code.Example
app.UseMvcWithDefaultRoute();
Custom Middleware
Custom Middleware allows you to create and add your own middleware components to the request/response pipeline, offering flexibility and customization.Example
app.UseCustomMiddleware();
Configure Middleware
The Configure method in Startup.cs is where you specify the order and configuration of middleware components in the pipeline.Example
public void Configure(IApplicationBuilder app)
{
app.UseMiddleware1();
app.UseMiddleware2();
// ...
}
Run Method
The Run method is used to terminate the request pipeline, sending a response directly to the client. It's typically used for short-circuiting the middleware pipeline.Example
app.Run(async context =>
{
await context.Response.WriteAsync("Hello, world!");
});
Add Built-in Middleware Via NuGet
You can extend ASP.NET Core by adding built-in middleware components from NuGet packages, enabling you to easily integrate new functionality.Example
dotnet add package Microsoft.AspNetCore.Authentication
Diagnostics Middleware
Diagnostics Middleware helps in monitoring and analyzing application performance by providing insights, logging, and instrumentation.Example
app.UseMiddleware<DiagnosticsMiddleware>();
