In this article, we will learn about clean architecture and will walk you through a sample CRUD API in .NET 8.0. Read the article on dev.to blog post Review the source code here

I created an Asp.Net Core 2.x Web API and configured Swagger on it, below is the code added in Configure method under Startup.cs file, for full swagger configuration, check here //Add swagger configuration app.UseSwagger(); app.UseSwaggerUI(c => {     c.SwaggerEndpoint( "../swagger/v1/swagger.json" , "Test API V1" ); }); On my local machine when I run the API it is automatically redirected to the Swagger page. However, when I hosted this API as an Azure web app it is not redirecting directly to the Swagger and to access the swagger, I had to append /swagger in the URL, for example, https://testapi.azurewebsites.net/swagger/ Solution: Set RoutePrefix to string.Empty under app.UseSwaggerUI like below: app.UseSwaggerUI(c => {     c.SwaggerEndpoint( "../swagger/v1/swagger.json" , "Test API V1" );      c.RoutePrefix = string .Empty; // Set Swagger UI at apps root }); And that’s it, now when you b...

Recently, while working with .Net core API I came across the issue of “Error 405 — Methods not Allowed” After some research, I found out that both GET and POST requests working fine but neither PUT nor DELETE requests working. Another thing is that the PUT and DELETE request was also working fine on my local machine but failed when we host on our Azure server. When I explored the issue on the web it led me to the conclusion that WebDAVModule seems to set PUT and DELETE request methods disabled by default and due to that PUT and DELETE throw 405 errors. To make the PUT and DELETE requests work, we need to override the WebDAVModule setting in web.config file by adding the below settings under “ system.webServer ”. < system.webServer >   < modules runAllManagedModulesForAllRequests = " false " >     < remove name = " WebDAVModule " />   </ modules > </ system.webServer > There may be 2 web.config files in y...

This is one of common issue one may face while working with Web API, there can be certain reasons due to which DELETE or PUT method not working with Web API. Here I’ll try to include three possible issues and there fixes: Possible issues and solution: Issue 1: Error: HTTP Error 405.0 - Method Not Allowed The page you are looking for cannot be displayed because an invalid method (HTTP Verb) is being used You are facing this issue because your application is not able to handles all types of HTTP requests. In order to execute HTTP requests for DELETE, PUT, etc., we need to add the below mentioned line in web.config file under < system.webServer > < modules runallmanagedmodulesforallrequests = " true " > Issue 2: Error: Getting 404 for PUT and DELETE request:  Issue may be due to because Web API provides default GET, POST, PUT and DELETE methods but IIS restricts it. To fix the issue you need to manage the handler mappings in IIS a...

In our last post we have created our first Web API and invoked the web API directly from the browser; in this article we will use jQuery/JavaScript for calling the Web API methods. So our Web API is already in setup and we’ll use same Web API methods (note that fixed list of Customer is updated only). Replace the code of Index.cshtml view with the following: < header >     < div class ="content-wrapper">         < div class ="float-left">             < p class ="site-title">                 < a href ="~/"> ASP.NET Web API </ a >             </ p >         </ div >     </ div > </ header > < div id ="b...
