P/Invoke boolean call always returns true in Release builds

I have a simple boolean function in a native C++ DLL (for keyboard input in my case), which I P/Invoke from C#. In debug builds, everything works fine. But in a release build (of both the C# and C++ projects), the C# side always receives true from the P/Invoke call, even when the native side returns false. I've checked my build settings but I can't figure out what is happening here- any recommendations for how to debug this or what could be the potential cause? ...

Question about reactivity in Blazor

Hi, I'm working on a Blazor project. I have some experience with C# in general and professionally I work with Angular. Specifically Angular recently tackled a big issue with reactivity with Signals. Before that I often used RxJS, and in .Net a similar implementation of RxJS is System.Reactive. In Blazor I do not fully understand how the reactivity works out of the box, without using any additional libraries. The goal of the project is to be able to parse replays of the game Supreme Commander: Forged Alliance and to show various information about the replay on different pages. Just like in Angular, one can use a service to deal with data that needs to exist across pages. To set that up, in program.cs I have the following snippet to make sure the replay service is a singleton: ```cs...

Random ERR_CONNECTION_RESET when uploading PDF files

I have angular SPA and .NET web API. One functionality is file upload, which usually works fine, but sometimes I am getting random ERR_CONNECTION_RESET errors which I can't explain. They only occur on PDF files and they are completely random. The file can be 50kb, or 5MB. Sometimes you can upload one file normally, later the same file fails 5 times. Funny thing is, the file is still sent and processed on the server, but I looks like something cancel/ignore upcoming response. One more problem is that this can only be reproduced when the apps are deployed on the server, when I debug it locally, everything works fine. Any idea what could be the problem? Honestly I don't know what should I even look for. Is this the API problem, or the ANgular application?...

Problems with compiling OLD-Projects

First, I decompiled the DLL file using DotPeak. Opened the .cproj file in Visual Studio. After searching for a solution to the problem on the Internet, I installed libraries 4.0 ( Microsoft.NETFramework. ReferenceAssemblies.net40 ) from the NuGet website into the frameworks folder. And this window as in the first screenshot disappeared. But after I compile the project, many errors appear like cs1525, cs 1002, etc. So, how can I work with an old project in the current version of Visual Studio?...

✅ Reading/Writing in Excel with C#

It seems there are plenty of options to read/write .xlsx files (EPPlus, OpenXML, ClosedXML, ...)? Are there some that are "more official" / "better" and that I really should use? Or are they all more or less the same?
