Fresh ASP.NET Core MVC projects throwing exceptions

So, I made a fresh ASP.NET Core Web App (Model-View-Controller) project in visual studio 2022 and .NET 6 like shown below.
When I start the project (without changing anything) I get the following 3 exceptions:
Exception thrown: 'System.IO.IOException' in System.Net.Security.dll
Exception thrown: 'System.IO.IOException' in System.Private.CoreLib.dll
Exception thrown: 'System.IO.IOException' in System.Private.CoreLib.dll
However the project still runs and the website opens as expected.
Are these exceptions something to worry about?

The fact that an exception is thrown is not a problem. Exceptions get thrown. That's what they do. It's a problem when they aren't caught and managed appropriately. If your code isn't even seeing those exceptions then they are being caught and handled in system code, so they're not relevant to you. If your application crashes, that is an unhandled exception, so you need to look at why it's being thrown and whether or not you need to prevent it and/or catch it and clean up.

why asp.net website dont work after publishing?

I made asp.net website, that work well on local (run debug in VS). But after I succesfully publish it (using VS) to a webhosting, the website does not work.
Problems started after I added references to some 3rd party DLLs and using them.
Did I miss something when referencing these DLLs?
Thank you for your time!

UWP resources not found

I have an UWP application which is working fine on various machines but on one particular machine, it is crashing silently.
When I debugged the installed app through visual studio I figured out that it is not getting the resources on the XAML file e.g
{ThemeResource ComboBoxDropdownContentMargin}
{Binding TemplateSettings.DropDownContentMinWidth, RelativeSource={RelativeSource Mode=TemplatedParent}}
The Output window is showing the following exception
Exception thrown at 0x751641E8 (KernelBase.dll) in
myapplicationnamechanged

An application-internal exception has occurred (parameters:

As per this MSDN documentation ComboBoxDropdownContentMargin was made availalbe from Windows 10, Version 1511 (Windows SDK version 10.0.10586.0).
So if you are running your App which has Version lower than the supported version, in that case, it will throw an exception.

A first chance exception of type 'System.IndexOutOfRangeException' occurred in mscorlib.dll

I have a WCF project (.NET 4.5) and when I call a long running function on it, I'm getting this error:
A first chance exception of type 'System.IndexOutOfRangeException' occurred in mscorlib.dll
in the output window, but the thing is when I debug the project, there are no exceptions thrown in the project and the project keeps running/debugging as if no error happened. I thought that if there was an exception in my code, it should break and show the stack trace, but in this case no errors and keeps running. I'm seeing this information like a lot. It fills the output window and keeps going/adding
Do anyone know what this error means? Why am I not getting unhandled exception thrown error if this is true?
