Asp net core web application not showing on creation of new project

ASP.NET is a popular programming language used for developing web applications. It provides a powerful framework for building dynamic and interactive websites. However, sometimes developers may encounter where their ASP.NET Core web application does not show up after creating a new project. In this article, we will explore some possible solutions to this problem.

One common for this issue is the configuration of the project. To resolve this, we need to ensure that the project is set up correctly. Let's take a look at the steps involved in creating a new ASP.NET Core web application.

First, open Studio and select “Create a new project.” Choose the ASP.NET Core Web Application template and provide a name for your project. Make sure to select the framework version and template, such as MVC or Pages.

Once the project is created, you may encounter the issue where the application does not show up. This can be due to reasons, such as dependencies or incorrect project settings. Let's explore some possible solutions to this problem.

Check Dependencies

One common cause of this issue is missing dependencies. ASP.NET Core relies on various NuGet packages to function properly. To check for missing dependencies, open the NuGet Package Manager in Visual Studio. Ensure that all the required packages are installed and up to date. If any packages are missing or outdated, update them to the latest version.

Verify Project Settings

Another possible cause of the issue is incorrect project settings. Open the project properties and navigate to the Debug tab. Ensure that the “Launch” dropdown is set to the appropriate option, such as “IIS Express” or “Project.” Also, check the “App URL” field to ensure it is correctly configured.

Rebuild and Run

If the above steps do not resolve the issue, try rebuilding the project and running it again. Sometimes, a simple rebuild can fix any underlying issues with the project. To rebuild the project, go to the Build menu in Visual Studio and select “Rebuild Solution.” Once the rebuild is complete, try running the application again.

Example

Let's take a look at an example of an ASP.NET Core web application that is not showing up after creation:


using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.;
using Microsoft.Extensions.Hosting;

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllersWithViews();
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            app.UseHsts();
        }

        app.UseHttpsRedirection();
        app.UseStaticFiles();

        app.UseRouting();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllerRoute(
                name: "default",
                pattern: "{controller=Home}/{action=Index}/{id?}");
        });
    }
}

In this example, we have a basic ASP.NET Core web application with the necessary configuration. However, if this application does not show up after creation, you can try the solutions mentioned above to resolve the issue.

To conclude, when an ASP.NET Core web application does not show up after creating a new project, it can be frustrating. However, by checking dependencies, verifying project settings, and rebuilding the project, you can often resolve this issue. Remember to follow the steps mentioned above and use the example provided to troubleshoot and fix the problem. Happy coding!
