Starting with the 2021.2 releases of our .NET productivity tools, including ReSharper and Rider (on Windows), we will require .NET Framework 4.7.2 or newer installed on your machine. Earlier versions of our .NET tools will continue to work on .NET Framework 4.6.1. 

Customers currently using .NET Framework 4.5.2, 4.6, or 4.6.1 need to update their deployed runtime to a more recent version – at least .NET Framework 4.6.2 before April 26, 2022 – in order to continue to receive updates and technical support. 

Among the over 100 API changes in .NET 6 are several features designed to make working with asynchronous code easier and safer. Here are some of the highlights.
