sure! I can provide you with a high-level overview of how to create a basic web application using either ASP.NET Web API or ASP.NET Core and set up routing. Here's a step-by-step guide for both frameworks:
1. ASP.NET Web API:
   - Open Visual Studio and create a new project.
   - Select "ASP.NET Web Application" as the project template.
   - Choose the "Web API" template and click "Create."
   - Visual Studio will generate the project structure with the necessary files and folders for a Web API application.
   Routing setup:
   - Open the `WebApiConfig.cs` file located in the `App_Start` folder.
   - In the `Register` method, you can define your routes using the `config.Routes.MapHttpRoute` method.
   - For example, to set up a route for the `Sum` operation in the previous calculator example, you can add the following line:
     ```csharp
     config.Routes.MapHttpRoute(
         name: "SumRoute",
         routeTemplate: "api/calculator/sum",
         defaults: new { controller = "Calculator", action = "Sum" }
     );
     ```
   - Repeat this step for each operation you want to expose via the API, adjusting the route template and specifying the appropriate controller and action.
2. ASP.NET Core:
   - Open Visual Studio and create a new project.
   - Select the "ASP.NET Core Web Application" template.
   - Choose the "API" template and click "Create."
   - Visual Studio will generate the project structure with the necessary files and folders for an ASP.NET Core API application.
   Routing setup:
   - Open the `Startup.cs` file located in the project root folder.
   - In the `Configure` method, you can define your routes using the `app.UseEndpoints` method.
   - For example, to set up a route for the `Sum` operation in the previous calculator example, you can add the following line:
     ```csharp
     app.UseEndpoints(endpoints =>
     {
         endpoints.MapControllerRoute(
             name: "SumRoute",
             pattern: "api/calculator/sum",
             defaults: new { controller = "Calculator", action = "Sum" });
     });
     ```
   - Repeat this step for each operation you want to expose via the API, adjusting the route pattern and specifying the appropriate controller and action.
Once you've set up the routing, you can implement the controller actions with the corresponding logic, similar to the example I provided earlier. Remember to handle input validation, error cases, and return appropriate HTTP responses.
These steps provide a general outline of creating a basic web API and setting up routing using either ASP.NET Web API or ASP.NET Core. For more advanced scenarios or specific requirements, further customization and configuration may be needed. It's recommended to consult the official documentation or online resources for more detailed instructions and examples tailored to your specific use case.
