Why is the antiforgery token in MS example appending the token only on "/" or "/index/html"

I'm working on an angular SPA front end and C# web api backend. I want to use antiforgery cookies. The front end and backend live on the same server on different ports (not sure if any of this is relevant to the question). I've got the antiforgery cookie correctly working - if I visit my page directly, www.mywebsite.com, then the token is appended and everything works fine.. However, if I visit my angular SPA starting at a URL that is not "/" or "/index.html" then the cookie is not appended and I get exceptions in my backend when trying to make calls. I think this is because I am implementing it as suggested here: https://learn.microsoft.com/en-us/aspnet/core/security/anti-request-forgery?view=aspnetcore-8.0#generate-antiforgery-tokens-with-iantiforgery ...

Utf8Json or Jil for Net3.5

Hey there! I'm trying to improve the performance of a game made in an older version of Unity that uses Net 3.5, and want to find a better JSON serializer and deserializer (current is JsonFx). I read about Utf8Json and Jil, but there don't seem to be any 3.5 versions available, even though I have read several articles and StackOverflow posts that mention them. Any help is much appreciated!

Questions/concerns about memory usage in my project

Apologies for the messy formatting, I created this post because of multiple concerns and/or observations while profiling it. The first part is that I'm not very familiar with how GC works or is expected to work. Clearly in the first screenshot the drops are caused by garbage collection, but I'm unsure what's causing the gradual rises in memory. Is this just normal behavior since it seems to always drop to around the same level each time GC runs? Second question: What could cause total memory usage to vary wildly over the duration of a project running? In my case, this is a Discord bot profiled by dotMemory over the course of >24 hours (second screenshot). It reached a peak of 4.91GB used, and now we're currently using 2GB and the lowest total memory used was about 1.3GB. Snapshots have not shown me anything extremely out of the ordinary, it's expected data to be in memory. The only confusing part is that there are large quantities of CancellationTokenSources (third screenshot), despite every instance of one wrapped within a using statement to ensure it was disposed of. I'm very new to disgnosing memory leaks and/or usage issues so if I'm expressing incorrect assumptions or missing anything extremely obvious, let me know. I can post screenshots of my snapshots or anything else that might be relevant if needed....

User built queries on objects

I'm looking at an old app that allows users to build queries to retrieve objects in a list that match that query. It is only querying off a single property on the objects: a Dictionary<string, string> . Each object's dictionary property will always have the same keys. In the current code, it is a massive mess of nested if/else statements. The flow goes like this: 1. User selects key from the dictionary's keys...

ILogger<T> extension method "pass the args".

I am trying to create an extension method on ILogger<T> called LogPermissionDenied. I have a custom IPermissionDeniedErrorFragment which is an auto-generated interface from Strawberry shake based on a GraphQL fragment, that doesn't really matter that much, it is just to provide some context. The ILogger<T> has a method called LogError with an overload that accepts an string message and a params object?[] args...

Uninstaller won't remove AppData\Local expanded files.

Hey all, new here. I have a .NET 6 WPF app with an installer project (Microsoft Visual Studio Installer Project 2022) I added and "mostly" works fine. The issue is that the uninstall is not removing the temp files. I have an AppData\local collection of expanded on-demand files, but when uninstalled, it leaves them behind. Is there a native way to have the uninstaller remove them, or do I need to make a CustomActions class to explicitly remove them?...
