Hi,
I am trying to add a style class to a blazor component, with isolated style method and when I add the style class on the blazor component located in the index.razor file, the blazor component disapears.
I am doing that on a Webassembly Blazor project.
So:
I have followig files:
-Index.razor, where I want to display the razor component
@page "/"
<PageTitle>Index</PageTitle>
<h1>Hello, world!</h1>
<div class="displayStyle">
<DisplayComponent/>
</div>
Welcome to your new app.
<SurveyPrompt Title="How is Blazor working for you?" />
-DisplayComponent.razor, where the component is defined
<div>
<h3>DisplayComponent</h3>
<h6>how cool, it works</h6>
</div>
-DisplayComponent.razor.css where the style class is defined
.displayStyle{
margin:7px;
}
So please help me understading and implement this concept of isolated style.
When I add class="displayStyle" on the display component in index.razor the content of the "DisplayComponent" disappear.
I keep testing but I can't manage implementing a class on a blazor component with isolating style metgod.
Give me some sugestions please. What I am missing?
Thank you.

I had discovered where the issue was, I am using google Chrome and I had to clear the cache memory, and when I did that I had to check more checkboxes.
I hope that my post help others.
Thank you,

Hello, We enabled Windows Authentication for our development website a few weeks ago.
Now, after I disable it, the site shows only the 401 page: Quote: 401 - Unauthorized: Access is denied due to invalid credentials. It doesn't offer a login box. It doesn't do anything no matter what URL you try to load, including the home index page, except show that 401 message.
I disabled Windows Authentication on the website and on the server. What could I be missing?
CLARIFICATION:
I disabled Windows Authentication through the IIS Administration plug-in in Administrative Tools. I disabled it at the server level and at the website level. If this is being caused by an overlooked application setting, which would that be?
SOLUTION:
While I disabled Windows Authentication, I failed to re-enable Anonymous Authentication. Doh! Now it works.
The difficult we do right away...
...the impossible takes slightly longer.

Did you enable some other form of authentication?
If not, why would you expect to get a login box/page?

I'm not expecting a login box, just pointing out that none appears, for completeness.

Then, at a guess, you're using some form of authorization restrictions. Without any enabled authentication methods, all users will be anonymous, and will only have access to resources that are explicitly marked as available to anonymous users.

Hello,
In an ASP .Net Core 8 API, we have an issue with the processing of a call that lasts longer than 2 minutes.
It lasts long because we have to parse a ton of files (call can be 5-6 minutes), we know this should be improved, but that's beside the point here.
In a previous version of this API (.Net Framework 4.8), this call used to last just as long, and the API did not reset the connection.
In the .Net 8 version, we get such a message :
Connection id "xxx" reset.
Connection id "xxx" sending FIN because: "The Socket transport's send loop completed gracefully."
Connection id "xxx" disconnecting.
After some googling and copilot'ing, we found that this seems related to Kestrel configuration, so we tried several things:
- serverOptions.Limits.KeepAliveTimeout = TimeSpan.FromMinutes(5);
- Changed a few parameters related to timeouts in IIS
- Changed the timeout parameter from the client app calling the API
.. but nothing works.
Does anyone have experience with this ?
It's clear that the timeout duration has to be adjusted somewhere, but we have no idea where to look.
Thanks in advance ![Smile | :)](https://www.codeproject.com/script/Forums/Images/smiley_smile.gif)

Ok, so problem solved, my colleague found the parameter that controls this, here's the info, hopefully it will help someone!
In the web.config, you can set the parameter requestTimeout to the value you want, as in :
<system.webServer>
<aspNetCore processPath=".\MyApp.exe" requestTimeout="00:05:00" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="OutOfProcess" />
</system.webServer>
Alternatively you can also set this parameter via the Configuration Editor in IIS.

I have an ASP.net MVC5 app publish on a host provider.
CAS trust level is FULL and app runs fine.
I want to move the app to another host but they only sport CAS Trust level High and below.
I found this reference earlier:
"ASP.NET MVC 5 does not support running in anything other than full trust. Microsoft have provided guidance for hosters to move away from using CAS trust levels and use proper OS-level isolation instead."
and forwarded it to the new provider.
They responded that they are running IIS10 and Windows Server 2019 and the statement above does not apply.
Could someone please answer definitively as to whether ASP.Net MVS5 apps require FULL Trust level on IIS10/Server 2019? Current link to source would be appreciated.

Your new hosting providers are idiots. Take your business elsewhere.
Just because the linked support article doesn't explicitly mention IIS10, that doesn't mean it "does not apply"; it means it applies to everything from IIS 6.0 (Windows Server 2003 SP2) onwards. Unsurprisingly, Microsoft don't go back and update every article written for one version of Windows every time a new version of Windows is released, just to add "still applies to Windows x.x".
CAS has been deprecated since 2009 / .NET Framework 4.0:
Enabling CAS Policy Compatibility Mode for a Project - .NET Blog[^]
Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.
The fact that your new hosting company are still using "security" techniques that have been deprecated for at least 15 years should have you extremely worried!

I built a simple 1 page site with Visual Studio 2022 using asp.net. It has a few buttons that display some images and 2 links to a subdomain. No additional modules were used... just published with straight VS.
The host I am using has the CAS trust level default as FULL and it works successfully if I leave it that way.
Now I want to change hosts and the new host does not support a FULL CAS Trust Level, only HIGH.
This is my web.config:

I asked my current host for tech assistance and they did not have an answer but suggested I comment code out of the <system.codedom> section. There is no code to comment out so it's obvious they did not even look at my web.config file.
What do I need to change either in web.config or VS to get it change to a CAS level of HIGH?

ASP.NET MVC 5 does not support running in anything other than full trust. Microsoft have provided guidance for hosters to move away from using CAS trust levels and use proper OS-level isolation instead:
ASP.NET Partial Trust does not guarantee application isolation - Microsoft Support[^]
For .NET Core / .NET 5+ applications, CAS has been completely removed.
If your host doesn't understand that, or won't adopt the recommendations, then all you can do is take your business elsewhere.

Hi Sir,
I'm already develop asp.net web application using Visual Studio 2019, when i want to publish the wep app on IIS, all the icon / image on my page not appear. Also no all folder that i create such as Images folder , Logs Folder not included in publish folder.
Can anyone help me? Really appreciate. Thanks

Based on such a vague problem description? No, nobody can help you.
You need to perform some basic diagnostics. Check how the images are referenced in the page; look at the source of the page in your browser to make sure the paths are correct; check the browser's network tab to see what response you get for the images; etc.
Nobody here has access to your system, so nobody can do that for you.

Is every file in your Images folder tagged as "Content"?
Click on the file in Visual Studio, then look in the Properties window below Solution Explorer. The Build Action for each file should say Content. If it doesn't, change it.

I have created a test ASP.NET Core MVC application in VS 2022.
I configured individual authentication so it automatically created a database in the (localdb)\MSSQLLocalDB database server for all authentication chores.
I need to deploy the test application to a web server along with its database.
Where in the application do I point it to the web server's database server? The appsettings.json file doesn't contain a connection string for the (localdb), so I don't know if that's the right place for a different connection string.
If you could point me in the right direction, I'll be grateful.
The difficult we do right away...
...the impossible takes slightly longer.
|
|
|
|
|
The connection string is normally stored in the web.config file. If you haven't yet, try searching the entire solution for 'localdb'.
Jack of all trades, master of none, though often times better than master of one.

Thanks Ron. I found the place where the default connection string is defined. Problem solved.

how to fix "assertion failed : unrecognized tag script" error

Probably by correcting the code that causes it. But unless you show us the actual code there is not much that can be suggested. Please edit your question and add complete details of the problem.

The error typically occurs when there is an issue with unrecognized tags within your application. This could happen if you are using a tag that is not recognized or if there's a syntax error in your markup. Show some code so we can understand the error rather than trying to read minds on where the issue is occurring. ![Smile | :)](https://codeproject.freetls.fastly.net/script/Forums/Images/smiley_smile.gif)
