Visual Studio
See release notes for Visual Studio compatibility for .NET 7.0, .NET 6.0 and .NET Core 3.1.
.NET Core 3.1 End of life
.NET Core 3.1 will reach end of life on December 13, 2022, as described in .NET Releases and per .NET Release Policies. After that time, .NET Core 3.1 patch updates will no longer be provided. We recommend that you move any .NET Core 3.1 applications and environments to .NET 6.0. It’ll be an easy upgrade in most cases. The .NET Releases page is the best place to look for release lifecycle information. Knowing key dates helps you make informed decisions about when to upgrade or make other changes to your software and computing environment.
