The .NET Ecosystem in 2021: Over half of .NET devs use C# 8, 46% do not use diagnostic tools, and other facts | The .NET Tools Blog

The .NET Core 2.1 RC 1 is now ready for broad testing and for production use.  

CommunityToolkit/dotnet: .NET Community Toolkit is a collection of helpers and APIs that work for all .NET developers and are agnostic of any specific UI platform. The toolkit is part of the .NET Foundation.

Entity Framework (EF) Core is the rearchitected and rewritten version of the Entity Framework object relational mapping engine for .NET Core applications. It is very light-weight, extensible, and cross platform.

However, high transaction .NET Core applications using EF Core face performance and scalability bottlenecks in the database-tier under peak loads. This is because, although you can linearly scale the application tier by adding more application servers, you cannot add more database servers to scale it.

But, if you use a distributed cache like NCache in your .NET Core applications, you can quickly remove these performance and scalability bottlenecks and handle extreme transaction loads.

One good example of using a single-method interface instead of a delegate is IComparable or the generic version, IComparable<T>. IComparable declares the CompareTo method, which returns an integer that specifies a less than, equal to, or greater than relationship between two objects of the same type. IComparable can be used as the basis of a sort algorithm. Although using a delegate comparison method as the basis of a sort algorithm would be valid, it is not ideal. Because the ability to compare belongs to the class and the comparison algorithm does not change at run time, a single-method interface is ideal.
