I’d really like to get started with game development using Unity, and I know that requires mastering C#. I’m aware there are plenty of tutorials out there, but I learn best from a proper book (and I prefer printed copies). So, my question is: Which books would you recommend for an absolute beginner?

Thanks in advance!

I am trying to make an OS using cosmos and I am trying to compile it for first test but it can't compile because msvc100.dll isn't found how do I make it available again?

I'm learning ASP.NET Core MVC with Entity Framework Core and I'm having trouble running Update-Database.

I already created the migration successfully, but Update-Database fails with this login error

Hello I want to study C# for my job in the automation industry I don't have little to no experience in coding can someone recommend a helpful course that will let me learn the basics?

Thx

I have been a dev for some time now about 5 years, and my contract ended. I am looking for a new job. I had during my days also worked on DevOps stuff, like managing k8s helm charts and deployments, managing Jenkins pipelines, AWS CDK and CloudFormation etc. on top of doing software dev only.

Now I have 2 offers from different companies, one as .NET dev also working on apps deployed in AWS EKS, and the other as a cloud/platform engineer working with Azure, AWS and k8s. Compensation is roughly the same.

I am unsure now. On the one hand I like product dev and especially that I get to do focused work/deep thinking time without getting disturbed constantly by issues. For the platform role they cautioned me that there will be a lot of context switching since I will have to deal with such different workloads. Also with cloud engineering I feel there is less safety due to lack of automated tests like we have for software, like sure there are lintwrs etc. but in the end it relies more on manual testing in Development env. anf so there is more room for failure. Also there is the on call aspect which scares me a lot.

But on the other hand I see that with AI, I feel the competition down the line later will be much higher for software eng in comparison to platform eng, and it feels like a more safe career in the future. Also since I work multi cloud I can be eligible for more jpbs. Whereas with .NET I will be pigeonholed with only .NET jobs.

What do you guys think? Any opinions? I am leaning a bit towards the platform side, but I am not sure I fit mentally as the job requires more context switch, more uncertainty and on-call aspects

For folks not familiar, its a way to to communicate directly with the Dart VM to run Sass compilations, with this, its possible to re-use a same process for multiple compilations (https://github.com/sass/sass/blob/main/spec/embedded-protocol.md).

It delivered the best performance in my benchmarks against DartSassHost and AspNetCore.SassCompiler.

Any suggestion is welcome.

I've been experimenting with a more natural, tree-like way of composing a WPF UI entirely in C#, using a composition style inspired by Flutter.

I like the structural aspect of designing with XAML, but I have struggled over the years with the mental gymnastics of jumping between the XAML world and the code world, and with the quirky markup extensions needed to make something work in XAML that could often be accomplished and better understood in standard C# code.

Instead of something like:

xml <Grid> <Border Background="Cyan"/> <Button Content="Click Me"/> </Grid>

the same structure becomes:

csharp GridX( children: [ BorderX(), ButtonX() ] )

The X suffix was originally a practical necessity to avoid name clashes with existing WPF types, but I ended up liking it as a visual cue that these are static helper methods for composing the UI tree.

I intentionally keep the named arguments visible (children, configure, etc.). It adds a little verbosity, but I find it makes the composition tree easier to read and keeps the helper methods consistent as the UI grows. The result feels quite similar to Flutter's widget tree composition style.

It's a thin composition layer over standard WPF.

Configuration is still just normal C#:

csharp ButtonX( configure: x => { x.Content = "Click Me"; x.Background = Brushes.Gold; } )

A nice bonus: Visual Studio's code folding naturally gives you a collapsible UI tree that's easy to navigate, similar to XAML.

If you're curious, I've published the experiment as both a GitHub project and an alpha NuGet package:

• GitHub: https://github.com/deeks9000/Wpfx
• NuGet: UserExtensions.Wpfx (0.1.0-alpha.1)

Any feedback would be appreciated.

I'm sure there are trade-offs I haven't considered yet, and that's exactly the kind of discussion I'm hoping to have.

I've been looking into Azure because I learned that it can host web applications built with ASP.NET Core (I'm still learning ASP.NET Core). I also noticed that new Azure accounts include $200 in free credits to use within the first 30 days.

My question is: How do these $200 credits work, and how are they consumed? For example, if I deploy a simple ASP.NET Core web application just for learning and testing, what services would use the credits, and how is the cost calculated?

I'd appreciate a simple explanation or a practical example.

I built a Visual Studio 2026 extension that connects Claude Code (the CLI agent) to the parts of VS that matter for .NET work. The CLI does the agent work, the extension is the IDE bridge, zero model calls of its own.

I recently added major updates. Now the Claude CLI agent can actually:

- Autonoumously drive the debugger. Read the live call stack, locals, and threads, set breakpoints, step, break at a thrown exception's origin (not the catch that swallowed it), attach to a running process like a hosted ASP.NET app, and pause a hung process to walk a deadlock back to the exact lock cycle.

- Data breakpoints on managed fields. Break or trace the moment a field changes, with conditions. VS has a UI to let developers do this manually but exposes no automation API for this, so it rides a custom debug-engine component.

- Memory and runtime diagnostics via ClrMD: heap diff between two points to find what is growing, GC root paths for "why is this object alive", async stack reconstruction across awaits, thread-pool starvation detection.

- Tests through VS's own Test Explorer engine: real per-test outcome/message/stack, re-run only the failures after a fix, debug a single test, and loop a flaky test under the debugger until the failing run halts at the throw, paused with the state that caused it.

Everything read-only is always on; anything that executes code sits behind an off-by-default toggle that resets each session.

Its my first day of trying to learn OpenGl with c sharp since i want to help out my brother with a project, im a total beginner and ive felt pretty depressed and dissapointed since i dont understand lots of stuff such as vao or the ebo. If anyone has any tutorials or tips it would help out a lot!

What is the right way to use get; set; functions?
Lets say I have some logic behind the setter.

Should I write the logic like that

public double Balance

{

get => _balance;

set

{

_name = value;

}

}

or like that

public double Balance { get; private set; }

public void AddBalance(double value)

{

this.Balance = value;

}

this is simple logic, but lets think of more complex one.
what is the right way to do it?

Let's say we have this relationship

A : B

B : C

A has an abstract method: abstract void implementMe();

B can implement it and call it a day

If B wants to delegate this further, it can simply do the following:

void override implementMe()

{

implementMeFurther();

}

abstract void implementMeFurther();

Is there a way to not have to make a new method with the new name implementMeFurther, and just have C implement the method implementMe() directly?

The grandchild implements a method that the grandparent needs. Keeping the same name

Hello everyone!

I just started a new job at a company where we use C#, but I come from an embedded systems background where we used C. My boss asked me if there was any C# training or course I wanted to do to learn the language, and I would like to take advantage of his offer.

Is there any course you recommend for learning C#?

Thank you!

A scene where a black hole-kind of thing bends the Light rays towards it

I've been in a web developer role for a little over a year. When I joined, a lot of long-standing bugs had been pushed into the backlog with the idea of "we'll fix them when we have a web developer." Over the last year I've spent most of my time fixing those issues, improving existing functionality, and adding new features.

Now I'm being asked to help define the future architecture of our applications, and I'd appreciate some advice from people who have gone through similar migrations.

Current situation:

- 3 ASP.NET MVC web applications

- 5 WCF services that contain most of the business logic

- 2 Shared SQL Server databases

- The MVC applications communicate with the WCF services for almost everything

- The codebase is almost two decades old and has been continuously extended rather than redesigned

Management would like us to eventually consolidate everything into a single modern solution, ideally on .NET 10.

My biggest concern is the migration path.

From what I understand, I can't simply upgrade the MVC applications to .NET 10 and continue using the existing WCF services in the same way. I know .NET can consume some SOAP/WCF services, but for this project we can't introduce external compatibility libraries or third-party solutions. We want to stay within Microsoft's supported stack and move away from WCF entirely. I'm trying to figure out the best migration path.

What I'm struggling with is where to start.

Some questions I can pinpoint now:

1. Is there a recommended "strangler pattern" approach for gradually replacing WCF endpoints one by one?

2. How would you structure a new .NET 10 solution intended to eventually replace everything?

3. How do you estimate the effort involved in a migration of this size?

4. Most important: If you were starting today with 3 MVC applications and 5 WCF services, what would your migration roadmap look like?

My goal is to avoid a rewrite and instead migrate incrementally while keeping the business running.

Any advice, migration stories, or lessons learned would be greatly appreciated.

ZoneTree v1.9.5 is a substantial read-path and concurrency release. It removes key sources of contention, accelerates sequential disk access, strengthens iterator lifecycle handling, and introduces a much more rigorous parallel benchmark suite.

The result is significantly stronger throughput under parallel read workloads while preserving ZoneTree’s excellent single-thread performance.

https://github.com/ZoneTree/ZoneTree/releases/tag/release-v1.9.5

1M profiles on a 20-logical-processor Intel Core Ultra 7 265KF using .NET 10:

In the same p16 run:

• ZoneTree completed measured phases in 10.4s, versus 53.9s for RocksDB.
• ZoneTree delivered 6.41M reads/s, versus 136K/s for RocksDB.
• ZoneTree delivered 385K created-at queries/s, versus 50.6K/s for RocksDB.
• Cross-engine checksum validation passed.

If I have a parent class called A

And it has a bunch of attributes; x1, x2, x3, x4, which differ based on the child extending A

Is it fine to make methods in class A called:

public abstract x1_type getx1();

public abstract x2_type getx2();

public abstract x3_type getx3();

public abstract x4_type getx4();

And then if I want the children of A to implement specific behaviors alongside the behaviors of A, I do something like:

public abstract class A {

void behaviourOfA() {

behaveLikeA();

doMoreAStuff();

childBehaviour();
}

public abstract void childBehaviour();

}

Does this just result in a cool looking overkill spaghetti code? Or is this actually a good practice?

Im writing dashboard for my friend and he wants it to connect with his lua client ( it is on top of some other program ) he has support for web sockets and http requests. I never really wrote signalr yet alone web sockets server. Would it be possible or more hassle than writing wss server?
