Bootstrap 4 در واقع یک اقدام بزرگ بود که پس از یک سال توسعه، بزرگی این اقدام در خط به خط کدها احساس می‌گردد. تصمیم گرفتیم تا نسخه‌ی اولیه‌ی آن را به اشتراک بگذاریم و انتقادات و پیشنهادات شما را بشنویم. برای بهبود و پیشرفت در این زمینه، بسیاری از اخبار مرتبط را در اختیار شما قرار می‌دهیم. امیدواریم که ما را در بهتر شدن یاری کنید.

WebAssembly, or Wasm, is on its way to becoming the next big thing in software development, allowing us to develop more reusable code across programming stacks. It will also enable the deployment of smaller packages more securely. This talk will focus on the view of a .NET developer using WebAssembly in their projects, whether client-side, server-side, or plugins.
