The async/await programming model introduced in .NET 4.5 is a game-changer for asynchronous programming . It significantly simplifies writing asynchronous code, making it more readable and maintainable. The performance improvements in the Common Language Runtime (CLR) are notable, with better memory management and faster execution for many operations . The framework also offers excellent integration with Windows services and enterprise applications, making it ideal for business-level development. Additionally, the extensive library support and comprehensive documentation make development smoother and more efficient. Review collected by and hosted on G2.com.

The lack of cross-platform support is a significant drawback—it's Windows-only . The framework has become legacy technology, with Microsoft focusing on .NET Core/.NET 5+ for future development . The heavyweight nature of the framework can lead to larger application deployment sizes. Some modern language features available in newer .NET versions are missing. The asynchronous programming model, while improved, still has limitations compared to more modern approaches. Review collected by and hosted on G2.com.

I like how stable and dependable .NET 4.5 is. It’s great for building scalable applications, and the overall ecosystem makes development easier. The support, documentation, and available libraries are also a big plus. Review collected by and hosted on G2.com.

Sometimes .NET 4.5 feels a bit heavy to work with, especially for smaller projects. The setup and configuration can take effort, and compared to newer technologies, it doesn’t feel as lightweight or flexible. Review collected by and hosted on G2.com.

As a developer, what I appreciate the most about .NET is how predictable and comfortable it is to work with. Debugging is smooth, IntelliSense actually helps, and the framework gives me enough structure without boxing me in. I also love how much performance has improved in the recent .NET versions. Building APIs that actually feel fast without doing crazy optimizations is a huge plus. Review collected by and hosted on G2.com.

while documentation exists, real-world examples for new features often lag behind, so I end up digging through GitHub issues or blogs more than I’d like. Review collected by and hosted on G2.com.

Modern web support, like WebSocket support and new bindings, was a big step forward. Async and await actually began with .NET 4.5, along with lots of new async APIs that helped make UIs more responsive and improved server scalability. Most importantly, HttpClient was introduced (if I’m not wrong), and after that it basically became the norm. Review collected by and hosted on G2.com.

Visual studio after 2022 cant build apps tragetting .net 4-4.5

majorly the 4.5 supported windows 7 vista etc environments which rsn thier course

many libraries , sdk's and intergations required 4.6 dependecny became impossible Review collected by and hosted on G2.com.

I've used NET 4.5 as an intermediary or orchestration layer for my ML projects.

Since most of the AI/ML projects reside in cloud, NET 4.5 acts as middleware. Due to async/await architecture, I was able to keep my AI applications responsive. Review collected by and hosted on G2.com.

It is a bit old when compared to newer versions. A lot of third party software/libraries require a higher version of NET. This sorta makes it impossible to have native support for new AI functionalities. Right now it's just a reliable middleware. Review collected by and hosted on G2.com.

I’ve used .NET Framework 4.5 mainly for developing Windows-based applications, and it’s been a very stable and reliable platform. The integration with Visual Studio makes coding and debugging much easier, especially for beginners like me. I also like how it handles memory and exceptions efficiently.

Because this is an older version, it lacks the modern cross-platform capabilities found in .NET Core or more recent releases. Some of the libraries seem somewhat outdated, and the initial setup process can be a bit more time-consuming than with newer frameworks. However, after everything is configured, it operates smoothly.

I like that .NET 4.5 is very stable and reliable. It works well for building desktop and enterprise applications, and features like async/await make the code easier to write and manage. The tooling support in Visual Studio is also very good, which helps in debugging and development. Review collected by and hosted on G2.com.

.NET 4.5 feels a bit old now. It doesn’t have many of the modern features and performance improvements that newer .NET versions offer. It’s also not ideal for cross-platform or cloud-native applications compared to the latest frameworks. Review collected by and hosted on G2.com.

Huge class library and a strong NuGet ecosystem. Strong typing and compile-time checks mean fewer runtime bugs. Excellent performance with Core/5+ and async/await. Review collected by and hosted on G2.com.

It can feel a bit heavyweight overall, and the runtime and SDK size are quite large. There’s also a learning curve for beginners, especially when it comes to C# syntax and understanding the project structure. Review collected by and hosted on G2.com.

The best ever feature introduced is the async and await functions, this made the asynchronous programs much simpler and its portable class of libraries which helped to share code across multiple channels Review collected by and hosted on G2.com.

While async or await was a great feature, it introduced complexity for developers unfamiliar with asynchronous programming as well as performance issues still persist. Review collected by and hosted on G2.com.

The built-in Zip compression in System.IO.Compression reduced dependence on external third-party libraries. Review collected by and hosted on G2.com.

It lacks cross-platform capabilities, restricting use to Windows, in contrast to .NET Core's compatibility with Linux and macOS. Review collected by and hosted on G2.com.
