ASP.NET Core features and specs

  • Cross-Platform Support
    ASP.NET Core is a cross-platform framework, which means you can run your applications on Windows, macOS, and Linux. This flexibility allows developers to target a wider range of environments without being locked into a single operating system.
  • High Performance
    ASP.NET Core is known for its high performance, being built from the ground up to optimize speed and scalability. It uses a modular framework architecture and supports asynchronous programming, making it suitable for modern, high-traffic applications.
  • Unified MVC and Web API Frameworks
    In ASP.NET Core, MVC and Web API frameworks are unified into a single framework, simplifying the development model for building web and API-based applications.
  • Dependency Injection
    Built-in support for dependency injection simplifies the management of dependencies across the application, promoting cleaner architecture and testability.
  • Open Source and Community Support
    ASP.NET Core is open source and has a strong community around it. This means that developers have access to the source code and can contribute to its development. It also benefits from continuous improvements driven by community feedback.
  • Cloud Integration
    ASP.NET Core is designed with cloud deployment in mind, providing features and templates for streamlined integration with cloud platforms such as Azure.

Possible disadvantages of ASP.NET Core

  • Learning Curve
    While powerful, ASP.NET Core can have a steep learning curve for developers new to the framework or web development in general, due to its comprehensive set of features and tools.
  • Maturity of Third-Party Libraries
    Compared to the .NET Framework, some third-party libraries may not be fully mature or offer as many features, given that ASP.NET Core is a more recent platform.
  • Frequent Updates
    ASP.NET Core has a fast release cycle, which can be challenging for developers to keep up with. Frequent updates can mean regular changes to the framework that might require adjustments in application code.
  • Limited Windows-Specific Technology Support
    Some Windows-specific technologies and libraries might have limited or no support in ASP.NET Core, which can be a disadvantage for applications heavily reliant on those technologies.

Opa features and specs

  • Full-Stack Development
    Opa is designed to be a full-stack language, which means it can handle both the client-side and server-side development within a single codebase. This reduces the need for context switching between multiple programming languages and can simplify the development process.
  • Security Features
    Opa includes built-in security features such as automatic data validation and prevention of common web vulnerabilities like XSS and SQL injection, potentially reducing the number of security issues in web applications.
  • Concurrency Support
    Opa natively supports asynchronous programming and concurrency, allowing developers to write efficient, non-blocking code without needing additional frameworks or libraries.
  • Integrated Web Development
    The language integrates multiple aspects of web development such as database, server, and client interactions, aiming to streamline the process and reduce the complexity of managing disparate technologies.

Possible disadvantages of Opa

  • Limited Adoption
    Opa is not widely adopted, which can result in a smaller community and fewer resources, tutorials, or third-party libraries compared to more popular web development languages and frameworks.
  • Learning Curve
    Developers new to Opa might face a steep learning curve due to its unique approach and syntax, which differs considerably from more traditional web development languages.
  • Tooling and Ecosystem
    The tooling and ecosystem around Opa may not be as mature or robust as those surrounding other more established languages, potentially leading to challenges in finding compatible tools or plugins.
  • Performance Overheads
    While Opa abstracts many details for developers, this abstraction can introduce performance overheads compared to languages that allow more fine-tuned control over performance optimizations.

  • The Case For Go Backends
    However, usage of a C# framework like ASP .NET Core or a Java framework like OfficeFloor are more than capable in the right hands. The key is to understand the tradeoffs of each language and framework, and to choose the right tool for the job. - Source: dev.to / about 2 years ago

  • Trying to learn ASP.NET core, but confused by the documentation
    Per https://dotnet.microsoft.com/en-us/learn/aspnet/what-is-aspnet-core, "ASP.NET Core is the open-source version of ASP.NET, that runs on macOS, Linux, and Windows. ASP.NET Core was first released in 2016 and is a re-design of earlier Windows-only versions of ASP.NET.". Source: over 2 years ago
  • How can I convince my boss not to use Windows Server?
    But how about you both get your wishes: ASP.NET Core? Use a Linux server - with which you are familiar with, to host the live/production version. And the web application itself can be locally developed and tested in ASP.NET on a Windows server, which is what your boss wants? Source: over 3 years ago
  • 3 Different Hosting Models in Blazor
    Let’s remember that ASP.NET Core is cross-platform and can run practically anywhere. If you find yourself using C # for all your development, this is probably the best scenario for you to use anyway. With it, you can deploy your web application, which would also contain your Blazor Wasm assets in the same location. - Source: dev.to / about 4 years ago

    We come across some web frameworks and technologies that we think will succeed, but they wither away as time passes by and don't succeed to the level we expected. Which web frameworks and or technologies did you come across that you thought would succeed but did not as per your expectations? For example, I thought that Opa Lang[0] and UrWeb[1] would succeed but did not, even though the ideas were sound. [0]... - Source: Hacker News / almost 2 years ago
  • Modern JavaScript:Everything you missed over the last 10 years(ECMAScript 2020)
    I think the Opa language was doing JSX-like code in the frontend before JSX http://opalang.org/ Both Opa and JSX were created in 2011. Opa had other innovations as well, such having the same code base run on both client and server (like Next.js). Unfortunately it didn't get traction and was abandoned by the creators. - Source: Hacker News / about 4 years ago
