Hi Ben,
Greetings from Syncfusion Support.
We let you know that our Syncfusion Blazor components are compatible with .NET 6 Release Candidate 1. We have resolved the compatibility related issues and included with 2021 Volume 3 release. We have planned to roll-out the release on or before 30th September.
So, we suggest you to upgrade your projects to Visual Studio 2022 and .NET 6 after 2021 Volume 3 rolled-out.
Regards,
Nevitha
