The article demonstrates how to write Service Extensions in .Net Core to configure Dependency Injection with Parameters.

Background:

Most of us while configuring services or setting up Dependency Injection in .Net Core, we used methods like UseApplicationContext or similar kinds of methods to configure services in .Net Core Startup. Today we will learn how to build something like that so that our Services, will be easily plugged in .Net Core Host Builder.(maybe Web or Default)

Today we will build a custom library to Easily Connect and Consume Azure Table Storages.

Redis has built-in replication, Lua scripting, LRU eviction, transactions, and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster.

Things Required:

  1. Docker Desktop for Creating a Redis Instance. if you…


Today, we will learn how to simulate IoT devices in .NET and C#. These simulated IoT devices will be sending the data to Azure IoT Hub. After we received the telemetry data in IoT hub, we can run Time Series Insights or we can configure Event Hub to process the data or we can also use Azure Stream Analytics which is a costly resource. So let’s get strated then…

What you need?

  1. Azure Account, don’t worry if you don’t have one create a free trial or you can use the Microsoft Learn Sandboxes. …


Today, we are going to discuss , how to inject dependencies in Function App host during the startup and will also use custom configuration file to read Application Settings and write logs and Telemetry data in Azure Application Insights.

Things Required:

  1. Azure Account and Subscription, if you don’t have, please use Microsoft Learn Sandboxes.
  2. VS 2019

Nuget Packages Required:

<PackageReference Include="Microsoft.Azure.Functions.Extensions" Version="1.1.0" /><PackageReference Include="Microsoft.Extensions.Configuration" Version="3.1.13" /><PackageReference Include="Microsoft.Extensions.DependencyInjection" Version="3.1.13" />

Please remember one thing, Microsoft.Azure.Functions.Extensions 1.1.0 does not support other packages > “3.1.13”, if you use the latest one, it will give an exception while loading the startup.

Stetps:


Today, I will show how to configure Azure Application Insights while developing the function locally. And where to configure the same after deploying in Azure.

What we need?

Access to Azure Portal, if you don’t have , don’t worry , you can create a Sanbox with Microsoft Learn to perform the same and VS2019.

Steps:

  1. Create a Resource Group
  2. Create a Application Insights Instance under that resource group and provide location for this instance.
  3. Open VS 2019.
  4. Create a new Project of Type Function App.
  5. By default, it will create a Function app named Function1, keep it as it is.


Problem: Count occurrences of Anagrams of a word in a string

Explanantion:

string is “forxxorfxdofr” and word is “for”

Anagrams of word are: 3! =6 “for”, “fro”, “orf”, “ofr”, “rof”, “rfo”

So anagrams present in the strings are “for”, “orf”, “ofr” and count will be 3

Code:


Problem : Find First negative number in every subarray of size k

Explanantion:

Lets say we have an array like this { 12, -1, -7, 8, -15, 30, 16, 18 }

Sub Arrays of size k(k=3) will be below,

{12,-1,-7} {-1,-7,8} {-7,8,-15} {8,-15,30} {-15,30,16} {30,16,18}

First Negative of each sub arrays will be -1,-1,-7,-15,-15,0(as there are no negative numbers)
