Unable to resolve service for type 'Microsoft AspNetCore Http IHttpContextAccessor'

If you are facing this error while migrating .net older version to .net core 7.0 -

InvalidOperationException:  Unable to resolve service for type  'Microsoft.AspNetCore.Http.IHttpContextAccessor'

InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Http.IHttpContextAccessor' while attempting to activate 'Controller'.  Microsoft.Extensions.Internal.ActivatorUtilities.GetService(IServiceProvider sp, Type type, Type requiredBy, Boolean isDefaultParameterRequired)

then For .NET Core 7.0 please try to add  the following code in the Program.cs class:

builder.Services.AddHttpContextAccessor();

This is equivalent to:

services.TryAddSingleton();

after that you can add other instance creation logic.

this is because of  IHttpContextAccessor is no longer wired up by default, you have to register it yourself.

i hope this will help, thanks for reading.
