Recently, I was creating an Asp.Net web application for a SharePoint POC where we wanted to display SharePoint list data using CSOM (Client side object model using C#.Net), but I got an error as: Could not load file or assembly ‘Microsoft.AI.Web’ or one of its dependencies.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.IO.FileNotFoundException: Could not load file or assembly ‘Microsoft.AI.Web’ or one of its dependencies. The system cannot find the file specified.
The full error looks like the below:

Install Microsoft.ApplicationInsights.Web from NuGet Package Manager Console

From Visual Studio, click on Tools -> NuGet package manager -> Package Manager Console.
Then, in the console, write the below command,
Install-Package Microsoft.ApplicationInsights.WebTo install it into a particular project, then run the below command.
Install-Package Microsoft.ApplicationInsights.Web <ProjectName>
Once you click on Enter after writing the above command, it will install Microsoft.ApplicationInsights.Web, and you will
