.Net Framework project complains about nullable not being supported in C# 7.3

I have a very old project my team is now working on and for some reason when I try to build it in VS 2022 I get the following error

Invalid 'nullable' value: 'Enable' for C# 7.3. Please use language version '8.0' or greater.

Invalid 'nullable' value: 'Enable' for C# 7.3. Please use language version '8.0' or greater.

There are two projects in here that use .net 6 and 7. Most projects are using net4.8 I checked the csproj files they don't have <Nullable>enable</Nullable>...

Identity, .NET Api and Angular client

Oh boy... anyone knows if its better to use cookies or token based authentication with Identity, Angular and .NET Api ? Are cookies a good practice, in my case ? I have an Angular application for the client, a .Net Api for the server, postgreSQL database with Identity. Everything seems to work just fine if I use Swagger to login and then to check WeatherForecast endpoint. I was following this guide : https://learn.microsoft.com/en-us/aspnet/core/security/authentication/identity-api-authorization?view=aspnetcore-9.0&source=recommendations . ...

'Emoji Translator': emoji-api.com doesn't work

I need to make a Emoji Translator for my school, and since I like challenging myself a bit, I wanted to use an API to get more emojis than just 10 pre defined emojis. Now when I use the emoji-api.com api, it says it loaded all the emojis (3k+), but they always just get outputtet as plain Text. (Code in the Comments)...

Stack overflow, but can't change the code

My issue is that I have a calculation that overflows the stack by a little bit (it's deterministic and will never increase past around 1.15 MB). I can't change the code to not do that, unless business approves some funds for serious refactoring, so the question is, how to proceed. I wanted to increase the stack size to 2MB for the one calculation thread, which seems pretty reasonable. But not sure what the best way to do that would be. Starting a new thread with the specified amount will mean I have to do some extra exception processing. How would I do that? Try/catch around the thread's code, and hoist the exception object out of the stack? Then rethrow from the outside? I will lose internal stack information that way, no? Throw a new exception on the outside, with the exception object as the inner exception? A bit more annoying to handle, but could work... are there any better ideas? This isn't a normal "thread" scenario, since I start the thread and immediately join it, I don't actually want anything to run in parallel, I only do it to increase the stack size. So does this give me other options? Runtime cost of spawning/joining a new thread in this scenario is irrelevant....

Child Window Not Fully Visible When Launching Executable in PanelHost"

• i have a Windows Forms application that displays ads and launches an executable within a panelHost control. • The application uses the CefSharp library to display ads in a Chromium browser and extracts and launches an executable from a ZIP file. • When i press the "Launch" button, the executable's window is not fully visible within the panelHost. It appears to be cut off in the middle, with only the upper part visible. Image used ai to fix it but it kinda makes it worse , and yes i am a beginner...

getting tcp connection state

im currently in following situation: we have a tcp architecture where more or less everything can connect to (local network). since devices conencting arent always behaving properly we cannot bet on graceful connection closing. as a workaround we are polling on IPGlobalProperties.GetActiveTcpConnections to forceclose connections and require a new handshake and datasyncing. we have the problem now though that with increasing amount of tcp sockets in windows (checked via netstat) that call gets rediculous slow and cpu heavy. more or less all i need is to check that the connection that is/was connected is still estabished. are there any alternatives i could use? would p-invoking GetTcpTable be faster? are there better apis?...

Why is `dotnet publish` not including Roslyn for my ASP.NET Framework 4.8.1 Web App?

I converted my .NET Framework 4.8.1 Web Application to SDK-style projects (like Microsoft recommended). I think I've worked out all of the quirks except for the publish piece. For some reason, the publish likes to modify my web.config and add stuff to it not included in the original. It also is not including the roslyn folder in the bin folder in the published output. ANYWAY. I worked around the web.config getting molested. Now I just (I think) need to find a way to include the bin\roslyn folder in the published output....

Selenium-unable to find element

Trying to run TestLogin(1st test) inside TestAddToCart(2nd test) then find an element afterwards, but unable to. I was able to find the element in the first test, but it doesn't seem to work in 2nd test. Not sure if it is allowed or there needs to be some kind of wait time. [Test] public void TestLogin() {...
