Starting with v19.2.1, we build DevExpress Blazor components to a RCL (Razor class library) to use a native way of resource sharing. See T850893 for more information. The RCL functionality requires the use of .NET Standard 2.1.
In v19.2.1, we also used the new functionality from .NET Core 3.1 to implement specific features and fix bugs.
So, if you have Blazor projects that target .NET Core 3.0, update them to .NET Core 3.1.
