Microsoft Cognitive Services - Bing Search

Microsoft cognitive services

In this article, I'll explain how we can use Microsoft Cognitive Services for Search API, step by step.

Step 1

To consume Cognitive Services, you should have an Azure account. If you don't have any, you can create free account.

Step 2

Click here and login.

Step 3

Now, follow these steps which I have marked into below image as follow.


Step 4

Create Search API. You can put the name you want and provide more information as below.


Click on "Create" button.

Step 5

Now, click on "All Resources" in left panel and then find your service which you have recently created. Bing Search Panel will open and follow these steps which I have marked on the below screen.


Step 6

Copy any one key and use it in your project.


Step 7

Now, create a new application and write the below code.

Note- To create JSON object, we need to create RootObject class. So, we can create RootObject class as follow. Right click on result and you will see JSON result. Copy JSON result and create a new class in your project.



After creating class, go to Edit menu and click on 'Paste Special'. Then, click on 'Paste json as classes' as follows.
