Re: Domain-Driven Design Fundamentals

arezkiStoreFront — Tue, 08 Oct 2024 18:15:04 -0000

Hi, I tried to run the application and did not manage to get it to work.

I added the the appropriate nuget package and installed RabbitMQ and paper cut; both worked. I opened the front desk solution and ran the FrontDesk.Api and it was successful.
I then right clicked on FrontDesk.Blazor, select debug and create a new instance and after 30 seconds I got: ProcessId 3952 is not running. Any idea on how to troubleshoot this problem.

Thanks

Re: Accessing APIs Using HttpClient in .NET 6

arezkiStoreFront — Fri, 17 Nov 2023 07:11:03 -0000

Hi Kevin,

Awesome as always, a small question I unzipped the exercises file and in folder 5 end.

In the class PartialUpdatesSamples, you have a method PatchResourceShortcutAsync

public async Task PatchResourceShortcutAsync() { var httpClient = _httpClientFactory.CreateClient("MoviesAPIClient"); //more code here ... }

The fact that it is a named instance, httpClient is the same instance each time and let us assume that I modify code PatchResourceShortcutAsync to

public async Task PatchResourceShortcutAsync(string token) { var httpClient = _httpClientFactory.CreateClient("MoviesAPIClient"); httpClient.DefaultRequestHeaders.Add("Authorization",token); //more code here ... }

If I have two separate thread that make a call to PatchResourceShortcutAsync with a different token, there would a threading issue ?
What I use is a SemaphoreSlim, as follows;

public class PartialUpdatesSamples { private readonly SemaphoreSlim _semaphore = new SemaphoreSlim(1, 1); public async Task PatchResourceShortcutAsync(string token) { await _semaphore.WaitAsync(); try { var httpClient = _httpClientFactory.CreateClient("MoviesAPIClient"); httpClient.DefaultRequestHeaders.Add("Authorization",token); //more code here ... } finally { _semaphore.Release(); } } }

Do I need the _semaphore ?

Thanks

Awesome course, do you have any links that details on how to implement XGBoost from scratch.

Re: ASP.NET Core with the New MSBuild Based Tooling

arezkiStoreFront — Thu, 04 Aug 2022 07:30:55 -0000

Awesome course, I downloaded the exercises files and I cannot see an example solution project where one can run build.ps1 script to compile and publish the project.

Do you by any chance one or a link to blog showing a solution project that uses msbuild from the command line.

Thanks
Jason

Hi Roland,

Outstanding course, I hope you will add a course which covers unit testing of minimal APi with CQRS.

Re: Unit Testing an ASP.NET Core 6 Web API

arezkiStoreFront — Mon, 09 May 2022 12:29:00 -0000

Hi Kevin,

In the course do you cover how to unit test minimal API, in other words:

In the program.cs, we can have:

app.MapGet("customers", async (IMediator mediator) => await mediator.Send(new GetAllCustomersRequest()));

Thanks
Jason

Re: Blazor: Getting Started

arezkiStoreFront — Sun, 13 Mar 2022 12:04:09 -0000

Hi Gill,

I am using .Net 5, I solved my Issue by:
In the BethanysPieShopHRM.App program.cs

I have this builder.RootComponents.Add<app>("#app");
instead of builder.RootComponents.Add<app>("app");

and in the index.html page I have:

<div id="app">Loading... current application</div>

Instead of
<app>Loading...</app>

The browser caches the index.html page so i needed to press
CTRL+F5

May be somebody might need this.

Awesome course :)

Any pointers:

I have added:

To the index.html

I have also added:

@using BethanysPieShopHRM.ComponentsLibrary
@using BethanysPieShopHRM.ComponentsLibrary.Map

To the import.razor

Any pointers?
Thanks

Hi Gill,

I found a solution, I am adding it here in case it may help somebody. I am using http and not https. I have done the following:

In ConfigureServices, I commented:

//services.AddCors(options =>
//{
/// options.AddPolicy("Open", builder => builder.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod());
//});

in Confugure I also commented and added:

// app.UseCors("Open");
app.UseCors(cors => cors
.AllowAnyMethod()
.AllowAnyHeader()
.SetIsOriginAllowed(origin => true)
.AllowCredentials()
);

When I do an update it works.
Thanks for the course

Thanks Gill for the quick reply.
I had to start both web and api and I needed to change one of the port because both application where using port 5000. I also changed the httpclient base url. I ran both the web part and api as a console and it worked.

Thanks again

Hi Gill,

I downloaded the code and opened the last solution, in other words

..\getting-started-blazor\07\demos\Demos\BethanysPieShopHRM.App.sln

When I click on get all clients I get the following:

I used the following code to get the string below:

var result = await _httpClient.GetAsync($"api/employee");

if(result.IsSuccessStatusCode)
{
var responseString = await result.Content.ReadAsStringAsync();
}

Re: Angular Security Using .NET 5 and JSON Web Tokens

arezkiStoreFront — Tue, 09 Nov 2021 10:09:49 -0000

Thanks for letting me know. The listeners need to know that using local storage in production is not secure.
HttpOnly is setup on the server side.

Hi Paul,

I have not had time to go through the course. I only looked at the Table of contents. One small question, in the UI (Angular) where do you store your access tokens ?
I cannot see any mention of HttpOnly which to my knowledge is the best way to store the access tokens.

Thanks
Jason

Re: Securing Angular Apps with OpenID and OAuth2

arezkiStoreFront — Wed, 30 Jun 2021 16:47:45 -0000

Hi Brian,

Excellent course, in module 3 you set response_type = "code" so that we could use PKCE. However, I cannot see how you sent the code_challlenge so that the token is retuned via the backchannel.
Do I need to send the code_challenge or does it happen automatically because response_type = "code".

Thanks

Thank you very much for all your replies, awesome course and I will look forward to getting the starter versions of the yaml files and have a good vacation Jason

Hi Erik,

Is it possible to add the start yaml files so that we could follow along and do the labs in module 8.

Thanks
Jason

Re: Fundamentals of Docker and Kubernetes for .NET Developers

arezkiStoreFront — Thu, 17 Jun 2021 05:41:03 -0000

I think it because I used yaml version in the project.

I still cannot access at seq.local.com

When you created a secret while deploying identity server, where can I find the scripts you used ?

Thanks
Jason

Hi Erik,

In the last module I followed the steps and then and I type:
k get all I get the following:
https://uploads.disquscdn.c...

the service/globomail-service and service/globoseq-service Ports are not the same as yours 31534 is missing.

How can I troubleshoot this ?

Thanks
Jason

Re: Fundamentals of Docker and Kubernetes for .NET Developers

arezkiStoreFront — Wed, 16 Jun 2021 17:17:12 -0000

Thank you very much

Is it possible to get yml for core and api project in your github repo ?
Alternatively, I could write them and you could correct me.

One more question, when you deployed identity server, you pushed the image to docker registry. If I wanted to use
my local images, can I use:

imagePullPolicy: IfNotPresent inside my yml file

Do you have a working example ?.

Thanks
Jason

Re: Fundamentals of Docker and Kubernetes for .NET Developers

arezkiStoreFront — Wed, 16 Jun 2021 11:35:42 -0000

Hi Erik,

In the Program.cs

Identity Server Project
...
.WriteTo.Seq("http://globoseq"); ;

Core Project
...
.WriteTo.Seq("http://globoseq"); ;

API Project
...

.WriteTo.Seq("http://globoseq:5341"); ;

In the Docker-Compose

- "5342:80"

In this correct ?

Thanks
Jason

Hi Erik,

In Module 7 (Adding a Database to Docker Compose)
in SQL folder setup.sh

./wait-for-it.sh globosql:1433 --timeout=0 --strict -- sleep 5s && \
/opt/mssql-tools/bin/sqlcmd -S localhost -i InitializeGlobomanticsDb.sql -U sa -P "$SA_PASSWORD"

"$SA_PASSWORD"

Do we need to put the password itself like "Sqlc0ntainersFTW!" as specified in the docker compose or leave it as is and it gets pulled from the docker compose ?

Thanks
Jason

I used localhost, 1434 and it works :)
I have noticed you also type localhost, 1434. I thought you had typed localhost:1434 my bad.

Re: Fundamentals of Docker and Kubernetes for .NET Developers

arezkiStoreFront — Wed, 16 Jun 2021 04:28:21 -0000

I am using the labs and things are working, Awesome course.

I am on Module 7, connecting to the database
for sqlexpress, I use MachineName\SQLEXPRESS and it works
I cannot manage to connect on port 1434, in other words localhost:1434. I tried machinename:1434 it did not work.
I also tried to list the servers using:

sqlcmd -L and I get an empty list.

Any suggestions ?

Thanks
Jason
