ILSpy 8.0

[christophwille]

ILSpy 8 is based on .NET 6.0 compared to .NET Framework 4.7.2 for the previous generations of ILSpy. All artifacts except the self-contained distribution are built framework-dependent, which means .NET 6.0.2+ must be installed prior to starting ILSpy.

Note - none of the following lists are exhaustive except of course the first one:

New Language Features

• C# 10: record structs
• C# 11: Required members
• C# 11: ref fields
• C# 10: Support DefaultInterpolatedStringHandler

• Updated pattern detection for Roslyn 4.4.0
