Microservices topics

Just built my first microservice API, and it's hacky. Any examples to follow?

johnson_earls — Wed, 23 Jul 2025 22:54:35 GMT

I just finished building my first microservices-based API, and it's ugly. Are there any online source examples that include two (or more) API microservices communicating with each other over a message bus, that also include authentication using both a local authentication database and/or OpenID Connect?

Moving to microservices from a monolithic environment

Scott_Johnson195 — Mon, 30 Dec 2024 19:27:56 GMT

We are looking at migrating our application to Azure instead of having it hosted at each client site.

Some of the processing is done through data events which looks to be pretty straight forward.

The issue we have is the time-based events that happen periodically. Everything I've read thus far doesn't seem to have information if it's possible to use a time-based event to trigger processing.

Does anyone know if this is possible and if so, how it's accomplished?

Question about Kubernetes Deployment tutorial on Microsoft Learn

KevinR91 — Fri, 15 Nov 2024 23:09:59 GMT

I am going through the tutorial Module on Microsoft Learn titled "Deploy a .NET Microservice to Kubernetes" and am on the third unit located here: https://learn.microsoft.com/en-us/training/modules/dotnet-deploy-microservices-kubernetes/3-exercise-push-to-docker-hub. I am stuck under the "Verify the Docker images by creating containers in the codespace" heading on the fourth step. It tells you to select the port for the front end and open the service in a browser. However, there were no ports here that the step seemed to suggest were already there and I had to set it up. Given that the port for the frontend service of this tutorial is 32000:8080 according to the docker-compose.yml file for this tutorial project, is this what I should put in the ports tab? If so, the service does not display in my browser when I click on the globe icon as instructed by the tutorial and all I see is an HTTP 502 message. What should I do so that I can view the service? The repository for this tutorial service is located at https://github.com/MicrosoftDocs/mslearn-dotnet-cloudnative in the dotnet-kubernetes folder and I have attached images as well of the discussed configuration and error message below:

How to increase the timeout of a Invoke-WebRequest call either globally or in web.config?

helpdeskaleer — Mon, 26 Aug 2024 16:22:02 GMT

If your program uses the now legacy API `System.Net.HttpWebRequest` and that `HttpWebRequest` throws a `System.Net.WebException` that reads `The operation has timed out`

Is it possible to change the timeout property in the System.Net.WebException via a web.config file by adding the correct add element name and value attribute?

Or possibly change it globally using the registry or a GPO?

I have already been advised to fix this using netsh http retries and some other settings and truth be told the issue could be on the opposite end of the connection where it also could be timing out; but it is unclear how to find that out.

The error looks like this:

System.Net.WebException: The operation has timed out.
  at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context)
  at System.Net.HttpWebRequest.GetRequestStream()
  at System.WebServices.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
  ....

I am running a web-services based .NET application; it like most .NET web-based applications has an XML configuration file in which you can specify <add key="some-keyname" value="some-valuename" />.

After the application reaches out to the enterprise server with a webservices request; eventually it times out; but the error message does not make it clear if we are talking about a timeout that comes from the enterprise server end or if the timeout is coming from the client end on the machines that I work on and can control.

It simply says in a dialog box that pops up with a title that reads Error

System.Net.WebException: The operation has timed out

(again, it doesn’t specify if the time out came from my end or the enterprise end)…and it goes on…with the rest of the stack trace to tell us where the exception came from:

at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context)
at System.Net.HttpWebRequest.GetRequestStream()
at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
at EGatewayClientCE.EGatewayService.BDSWse.ProcessDimeRequest()
...etc

Open Source Microservices Platform Now Available

holomodular — Fri, 24 May 2024 10:27:01 GMT

Hello! I have recently published a new open source microservices platform on GitHub. It is available under the MIT permissive license and is free to use for commercial purposes. I'm asking the .NET community for some help. https://ServiceBricks.com

I am currently BETA testing and I'm looking for developers and architects to help me with the final push to make it production ready. I could use another set of eyes to help shore up the last remaining bits.

ServiceBricks is a powerful platform designed to streamline the development, deployment, and maintenance of distributed systems. It provides domain-driven design, event-based architecture and a wealth of features to rapidly build new microservices and application quickly. Deploy single monoliths or distributed, multi-web applications using docker or kubernetes.

There are several pre-built microservices to start from to build your own application infrastructures. They are also open source and all source code is available.

Please drop me a line if you would like to help! I'm looking for discussions on microservices architecture and how they are implemented in code.

Thanks!

.NET Aspire Vs. Service Mesh

gkarwchan — Mon, 29 Jan 2024 03:47:38 GMT

.NET Aspire has lots of overlap with Service Mesh on Kubernetes. like Istio.

But lack some features.

Was the intention to be a full Service Mesh?

Why I should use it, if I am using service mesh like Istio

I want to create a web API in ASP.NET C# that needs to run scheduled jobs from the app.

Nikhil2803 — Mon, 13 Feb 2023 09:57:27 GMT

Since, A and B are two different system altogether, there is no way to connect these two apps directly. So, I want to create my app in such a way that It will connect to an azure function and that azure function will act as a mediator that can get inputs(Payload) from the external system B and run the jobs of A. On this, the complexity of the Payload generation & API Call is shared by the Azure & On-premise EXE. The EXE will call the right Azure Job and the Job workflow is handled by Azure . Please help me the way to build the API/console app in C#.

Without Azure function, I am not getting any options to connect to any external app to get the payloads. Need to know about the way to connect to Azure so that azure can act as a mediator to connect these two external apps.

How to have dynamic Jittered Back-off for wait and retry in .Net core using polly

coder1232045 — Wed, 27 Jul 2022 12:03:01 GMT

Hi,

I am implementing wait and retry using jitter see below. In the example below the delay is same.

How can I make delay dynamic?
var delay = Backoff.DecorrelatedJitterBackoffV2(medianFirstRetryDelay:TimeSpan.FromSeconds(1), retryCount: 3);
var retryPolicy = Policy.Handle<FooException>().WaitAndRetryAsync(delay);

In my Project, I have Azure function https://docs.microsoft.com/en-us/azure/azure-functions/functions-dotnet-dependency-injection

public class Startup : FunctionsStartup
{
    public override void Configure(IFunctionsHostBuilder builder)
    {
        var configuration = builder.GetContext().Configuration;
        builder.Services.RegisterService(configuration);
    }
}

public static IHttpClientBuilder RegisterService(this IServiceCollection serviceCollection,IConfiguration configuration)
{
    return serviceCollection.AddHttpClient<IService, Service()
               .AddPolicyHandler(RetryPolicyHandler.GetRetryPolicy())
}

public static IAsyncPolicy<HttpResponseMessage> GetRetryPolicy(IConfiguration configuration)
{
    var delay =Backoff.DecorrelatedJitterBackoffV2(medianFirstRetryDelay: TimeSpan.FromSeconds(1), retryCount: 3);
    return HttpPolicyExtensions.HandleTransientHttpError().WaitAndRetryAsync(delay);
}

If you see the update code. Startup class override configure method that call register service>RetryPolicy.

Startup-> Configure-> Register Service -> RetryPolicy

My understanding is RetryPolicy will be called once (function startup) that will set the delay duration. Correct me if I am wrong?

Sorry I am new to polly and github wiki does not have this information.How can I make delay dynamic?Please advice. Thanks

OneDrive Sync Folder shows processing changes

Frederick_2101 — Fri, 28 Jan 2022 08:09:34 GMT

I have installed the latest semi annual version for OneDrive sync client

Some folders in the OneDrive sync folder shows processing changes under status. When the folder is opened, all files in the folder are completely synced. There are no temp files or hidden files in such folders, yet the sync status for this folders show processing changes.

I followed guidelines in this KBI <OneDrive is stuck on "Sync pending" (microsoft.com)> to create a new folder, copy all files in the affected folder to the new folder and this resolved the issue; the processing change symbol was replaced by a cloud symbol.

However, this issue affects many folders of almost all users of OneDrive for business in my tenant and most of these users are very busy and cannot create new folders and move or copy the contents into a new folder to resolve the issue each time its happens. This issue may look very simple but it is an issue that creates confusion in the minds of users as they doubt if their files have actually synced to their OneDrive accounts in the cloud.

Is there an alternate way I can fix this issue in my Tenant for all the users.

Any Service Fabric Evangelists still out there?

Stoepatjie — Fri, 05 Nov 2021 20:05:52 GMT

We are heavily invested in Service Fabric and all our new microservices are built on top of SF. We use about 70% of the capabilities of SF.

I sometimes feel we are the only ones left, and the rest have either headed over to Kube or another orchestrator.

Please let me know if you still feel SF was the right choice for your product, and if not what have you replaced it with?
