ASP.NET features and specs

Performance
ASP.NET is known for its high performance and scalability. It compiles server-side code to DLL files, which is executed on the server side, thereby speeding up the application's response time.
Security
ASP.NET provides built-in security features like form authentication and Windows authentication, as well as protection against common threats such as SQL injection, cross-site scripting, and request forgery.
Rich Toolbox
Visual Studio, the Integrated Development Environment (IDE) for ASP.NET, offers a rich toolbox with a plethora of controls, automatic deployment features, and other tools that significantly speed up development.
Cross-Platform Support
ASP.NET Core is a cross-platform framework, which means you can run your web applications on Windows, Linux, and macOS.
Community and Support
ASP.NET has a strong community and extensive documentation, making it easier to find solutions to problems and ensuring continuous improvement and support.

Possible disadvantages of ASP.NET

Learning Curve
The framework can be complex for beginners, especially those without experience in C# or the .NET ecosystem.
Cost
While ASP.NET Core is free and open-source, some advanced features and tools require a Visual Studio subscription, which can be expensive.
Hosting
Although ASP.NET Core has improved in terms of cross-platform hosting, traditional ASP.NET applications are primarily optimized for Windows servers, limiting hosting options.
Resource Intensive
ASP.NET applications can be more resource-intensive than applications built with some other frameworks, which can lead to higher infrastructure costs.
Complexity
The framework offers a lot of features and functionalities, which can sometimes make it overly complex and harder to manage for smaller projects.

Blazor features and specs

Single Language
Blazor allows developers to use C# for both client-side and server-side development, reducing the need to switch between different languages and enhancing developer productivity.
Full-Stack Development
With Blazor, developers can build full-stack web applications using .NET, leveraging the vast .NET ecosystem and tools.
WebAssembly Support
Blazor WebAssembly enables running C# code directly in the browser, allowing for rich interactive web applications with less reliance on JavaScript.
Reusability
Blazor promotes code reusability by allowing shared code between server and client-side applications.
Components-Based Architecture
It uses a component-based architecture that facilitates easier maintenance of code and enhances modularity.

Possible disadvantages of Blazor

Performance Limits
Blazor WebAssembly can have slower performance compared to JavaScript due to its intermediated execution through WebAssembly.
Download Size
Blazor WebAssembly applications can have larger initial download sizes, which can affect load times and user experience.
Newness
As a relatively new technology, the Blazor community is still growing, which can sometimes limit the availability of third-party tools and resources.
Limited Browser Support
Some older browsers do not support WebAssembly, potentially reducing the reach of Blazor applications if not accounted for.
Learning Curve
Developers familiar with JavaScript frameworks may encounter a learning curve when transitioning to Blazor and the .NET ecosystem.

Is ASP.NET Core the next step in my career being an ASP.NET MVC developer? Or are there other technologies I should look at?
Sorry for the possibly dumb questions. But then does .NET 5 have a "Model View Controller" workflow? I'm seeing ASP.NET still exists. But it's just "ASP.NET", no "MVC" or "Core" attached to the end. And they seem to recommend Blazor instead of C# which is something I only know the name of. Source: about 2 years ago

What is a good reason to consider Blazor?
Hi there. I'm the Program Manager at Microsoft for Blazor, so naturally I'm happy to make the Blazor pitch 😊.
