How to Run two .net core apps with debugging On using Visual Studio Code ?

When developing a web application we separate our application with *.web being initial server-side application and  *.api application which will help us fetch/update data for client-side operations and avoid page reloads. Photo by  Vincent van Zalinge  on  Unsplash Here is .NET Core application I was working on which had a similar kind of ask, and I wanted to use VSCode to debug my application. This is how we do it, first, we need to create a solution so that we keep both the API and Web project in one place dotnet new sln -n appname dotnet sln add src/appname/appname.web.csproj dotnet sln add src/appname/apname.api.csproj Open "launch.json" and Click on add configuration and add then select .NET Core Launch (web)  No go ahead and rename to web or web-api, also add a development URL with a different than web configs the "env" property "env": { "ASPNETCORE_ENVIRONMENT": "Development", "ASPNETCORE_URLS":

Setting up docker with Hyper-V

Docker is just amazing with flexibility we get to not worry about setting up the environments for our application. --Photo by  Ilse Orsel  on  Unsplash Download docker for windows .

Load Testing an nodejs API

Load Testing is quite a stream of its own all I did was smoothly sailed on top of it. With not much time in hand, the only weapon of choice was Jmeter, Well quite brilliant a tool!! We had to test a facebook chat-bot built with nodejs. This app is a webhook for FB to push the chat messages down to our app. This is how we achieved it On Windows: Download JMeter from  here . Now run the jmeter.bat, this will open up a java GUI where you can easily configure the endpoints you want to test. Add a thread group and set the number of users/thread you want to spawn to test your API Add an Http request sampler  Fill in the intuitive fields like URL, request body, Method, etc., For setting up HTTP headers like content-type or authorization fields right click on HTTP request and add config element HTTP header manager, then the key values as you may To see the results on all the requests that will spawn create add listener View results tree.  You are ready to click on play bu

Simply Notes #3: Multiple File Upload in ASP.Net MVC

Here is requirement I tripped into "Give me an option to upload multiple images which blah blah blah". Blah blah part is where it says do not use the easy way like input type multiple . Below is the POCO  for this sample which is the View Model Checkout the UIHint attribute which will let us use DisplayFor or EditorFor in any of the views To make this control reusable create a template File.cshtml which is type bound to custom Image type The jQuery script will copy the input type file element and appends to the last file element whenever a file is selected to upload on the input element. The Action here is to ModelBind image array to the action parameter The Bind  attribute takes care of the naming convention that takes behind the scenes when rendering the element. If you are using the template to render any element the framework will append the model property names of the nested elements. In this example it will render input element with name="PIma
