@yashints @rob-foulkrod @unaihuete93 @petender I would love to have your validation to this upgrade. For sure, I'm not asking to check file by file since it's huge but let me know if it's working fine for you thinking on AZ-400. The same project will be used in the new course DevOps Foundations.

This pulls request includes changes to the eShopOnWeb project to upgrade it from .NET 7.0 to .NET 8.0. The most significant changes include updating the Docker configurations, modifying the GitHub workflows, and updating the project's dependencies.

Starting the review process now. There is a lot to go thru. :) I am getting a build warning due to an obsolete overload in 'src/ApplicationCore/Exceptions/EmptyBasketOnCheckoutException.cs'. Near as I can tell, the following method is old boilerplate and can be deleted.

protected EmptyBasketOnCheckoutException(System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context) : base(info, context) { }

Once delete, everything builds, and test run without warnings.

@rob-foulkrod @yashints all fixed. I planning to approve this PR on Friday, so it fixes issues from AZ-400 and AZ-2008 new labs. Please, let me know if you see any issues and approve if possible! Thanks!

Runs and tests are all good

Hi there

I was just doing the LABS for AZ-400 since I am going to teach it in a few weeks as MCT.

In this lab:
https://microsoftlearning.github.io/AZ400-DesigningandImplementingMicrosoftDevOpsSolutions/Instructions/Labs/AZ400_M09_L16_Monitoring_Application_Performance_with_Application_Insights.html

When I have deployed the app for the first time and try to access it (according to the lab guide), i get a
HTTP Error 500.30 - ASP.NET Core app failed to start

When i look in the log files i found this error:

<EventData>
            <Data>Application '/LM/W3SVC/857545966/ROOT' with physical root 'C:\home\site\wwwroot\' hit unexpected managed exception, exception code = '0xe0434352'. First 30KB characters of captured stdout and stderr logs:
Unhandled exception. System.UriFormatException: Invalid URI: The URI is empty.
   at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind, UriCreationOptions&amp; creationOptions)
   at System.Uri..ctor(String uriString)
   at Program.&lt;Main&gt;$(String[] args) in /home/vsts/work/1/s/src/Web/Program.cs:line 32
   at Program.&lt;Main&gt;(String[] args)
</Data>
            <Data>Process Id: 6940.</Data>
            <Data>File Version: 18.0.23334.1. Description: IIS ASP.NET Core Module V2 Request Handler. Commit: </Data>
        </EventData>

Which did make me loot at the source for Program.cs at line 32, where i see this:
builder.Configuration.AddAzureKeyVault(new Uri(builder.Configuration["AZURE_KEY_VAULT_ENDPOINT"] ?? ""), credential);

This code was added in the this commit: c656d9b

Since there is no AZURE_KEY_VAULT_ENDPOINT in the configuration it ends up being "" (Empty), and we get this error.

So the 'Updating dotnet to 8.0 and sync project' commit seems to have broken a lot of LABS. :-(

A few days ago I tried another AZ-400 lab, and had the same error.

Hi @theDiverDK,

Can you confirm if this has already been addressed in the following thread?

#108 (comment)

You need to follow the lab instructions from GitHub if your lab provider hasn't updated theirs.

Hi @lauraAlvEl

I can confirm, adding:

UseOnlyInMemoryDatabase = true
ASPNETCORE_ENVIRONMENT = Development

To configuration did solve the issue.

In 5 minutes, I am going through the whole lab, from:
https://microsoftlearning.github.io/AZ400-DesigningandImplementingMicrosoftDevOpsSolutions/Instructions/Labs/AZ400_M09_L16_Monitoring_Application_Performance_with_Application_Insights.html

To check it again :)
