What is concurrent programing? Simply described, it’s when you are doing more than one thing at the same time. Not to be confused with parallelism, concurrency is when multiple sequences of operations are run in overlapping periods of time. In the realm of programming, concurrency is a pretty complex subject. Dealing with constructs such as threads and locks and avoiding issues like race conditions and deadlocks can be quite cumbersome, making concurrent programs difficult to write. Through concurrency, programs can be designed as independent processes working together in a specific composition. Such a structure may or may not be made parallel; however, achieving such a structure in your program offers numerous advantages.

AspNetCoreRateLimit is an ASP.NET Core rate limiting solution designed to control the rate of requests that clients can make to a Web API or MVC app based on IP address or client ID. The AspNetCoreRateLimit package contains an IpRateLimitMiddleware and a ClientRateLimitMiddleware, with each middleware you can set multiple limits for different scenarios like allowing an IP or Client to make a maximum number of calls in a time interval like per second, 15 minutes, etc. You can define these limits to address all requests made to an API or you can scope the limits to each API URL or HTTP verb and path.

Earlier this week, Microsoft published the roadmap for .NET Core 2.1, ASP.NET Core 2.1 and EF Core 2.1, expected to be out in the first quarter of 2018. The team also talked about several new features with this new release. This release is more of a feedback-oriented release based on .NET Core 2.0 release. The.NET Core 2.0 is a huge success and already more than half a million developers are now using .NET Core 2.0. All thanks to .NET Standard 2.0 release . In this post find out about the new features of .NET Core 2.1.
