We are excited to release .NET 6 Release Candidate 2. It is the second of two “go live” release candidate releases that are supported in production. For the last couple months, the team has been focused exclusively on quality improvements. There are a lot of new features in the release, which only fully come together near the end. The team is currently validating end-to-end workflows to find the places where design intentions and technical reality don’t yet fully match. That’s led to teams tightening leaky pipes and paving paths all the way to their destination. 

A clean, flexible, and fully customizable persian date picker. User can navigate through months and years. The datepicker shows dates that come from other than the main month being displayed. These other dates are also selectable.

Node.js is a rapidly growing technology that has been overtaking the world of server-side programming with surprising speed. MongoDB is a technology that’s revolutionizing database usage. Together, the two tools are a potent combination, thanks to the fact that they both employ JavaScript and JSON.

"We migrated Stack Overflow's ad server from .NET 4.6.2 to .NET 5.0 and we are testing it on a canary server in production. We are seeing big improvements in memory usage and in server response times. It wasn't the main goal of the migration, but definitely a nice to have" / Twitter
