Experimental support for the .NET 6 preview is now available in the latest beta:https://www.linqpad.net/linqpad6.aspx#beta
Let me know how you get along.
I installed both .NET 5 Preview and .NET 6 Preview,
I can find .NET 6 in current query's .NET version list. But for default Framework version, Preference->Query->Default Framework Version combobox not list.NET 6 Preview. .NET 5 preview is included, Is it a bug?
