Reading MSDN document what does this mean while reading local function
One of the useful features of local functions is that they can allow exceptions to surface immediately. For iterator methods, exceptions are surfaced only when the returned sequence is enumerated, and not when the iterator is retrieved. For async methods, any exceptions thrown in an async method are observed when the returned task is awaited.I can understand with async method so while returning async only we will come to know about exceptions. Just for understanding so
For iterator methods, exceptions are surfaced only when the returned sequence is enumerated, So this means when we enumerate like the collection is read like using for loop. But what this means and not when the iterator is retrieved3 replies
Can anyone explain Bulkhead policy in polly
Can anyone explain Bulkhead policy in polly
I want to send API calls to an external API that only allows 10 calls per second. Therefore, I need my program to be limited to making only 10 HTTP calls per second. Additionally, if I encounter a 429 error (too many requests), I want to retry that call. I learned about the Bulkhead pattern from this article: https://medium.com/@ynskrn54/using-polly-and-the-bulkhead-pattern-in-net-f4a9639e2fcd, which helps in preventing overwhelming the external API.
I have written some code based on this pattern. My understanding is that this code will manage 10 calls at a time in a queue. For instance, if I have 30 HTTP calls to make, they will be queued and processed at a rate of 10 calls per second.
Is the below code serve my purpose

How does option work in .net core
I have the below class here the contentfulclient base has a class called ContentfulClientBase which has a property called as contentfuloption with some property. I want to assign the value to one of the property. I have my own contentfuloption class which has some of the properties of ContentfulClientBase class contentfuloption. I want to pass my model value to contentfulclientbase class. But I don't know how to achieve it. When I use
_options = options.Value; I get an error states type to type conversion is not possible.
Basically I want my baseclass property should get my value which I provide.
public class ContentfulManagementService : ContentfulClientBase, IContentfulManagementService
{
private readonly ILogger<ContentfulManagementService> _logger;
private readonly Models.ContentfulOptions _contentfulOptions;
public ContentfulManagementService(
HttpClient httpClient,
ILogger<ContentfulManagementService> logger, IOptions<Models.ContentfulOptions> options)
{
_httpClient = httpClient;
_logger = logger;
_contentfulOptions = options.Value;
}
}

❔ How bit wise shift operation work
I started learning bit wise operation.
So i have a uint = 0101 bit which is int 5. Which is in loop to see how it works
Consider n =0101
1st iteration
var test = (n >> 0) // The value is 101
2nd iteration
var test = (n >> 1) // The value of test is 50
How this Happens what i assumed is 0101 on 2nd iteration will become as 1010 so it will be 9. But how it becomes 50.
