In this series I answer various .NET questions. Some of them are asked during interviews, some of them I see on the internet, some of them are completely made up. The goal is to provide short answer with links to references if needed. This is by no means a .NET tutorial or experts reference, this is just a bunch of useful answers to refresh your knowledge. 

You'll often hear the terms framework and platform used interchangeably. This can be very confusing. You'll hear that .NET Core is a platform. Then you'll read that .NET Core is cross-platform. Next, you'll learn that .NET Core is a framework. And it doesn't help that framework is part of the name of the original full .NET Framework.

In this post, I explain the difference between frameworks and platforms and explain why sometimes you'll see .NET being referred to as a framework and other times see it referred to as a platform. 

In .NET 6 (preview 4), two long-awaited types have been introduced as part of the core library. DateOnly and TimeOnly allow developers to represent either the date or time portion of a DateTime. These two new types are structs (value types) and may be used when your code deals with date or time concepts independently. Both types can be found in the System namespace. Using these new types may align well with how databases allow similar data to be represented. Specifically, these types align well with the SQL Server date and time data types. 

These are the customer-reported issues addressed in 15.9.9:
