Details

• Product in use: ILSpy 8.0.0.6933-alpha1 (Debug)
• Windows 7 SP1 x64

PS latest release - ILSpy version 7.2.0.6844 runs OK

[siegfriedpammer]

ILSpy 8.0 uses .NET 6.0 and according to https://github.com/dotnet/core/blob/main/release-notes/6.0/supported-os.md Windows 7 is only supported, if you have access to "extended security updates", which (I guess?) you get via a support contract with MS.

[greenozon]

Yeah, that might be a potential reason, but I did try to investigate more
so I've opened up .hdmp from ILSpy and inside VS I've found this:

the quesiton is: why the basic issue like on pic leads to silent crash?

[greenozon]

Is it possible to catch these exceptions @ ILSpy level and be more user friendly to end user?

[greenozon]

Issue tracked down and fixed

the bug was somehow inside the very 1st GA release of .NET6 - version 6.0.100,
after I"ve removed it ILSpy 8 alpha started up successfully! but complained I need to install .NET6,
so after installing this -
.NET 6.0 Desktop Runtime (v6.0.3) - Windows x64 Installer!
the IL8 successfully booted up @win7 x64!!!

BTW, why IL8 shows > 1 About tab? :)
proposing to show just 1

[yyjdelete]

For WPF, it's an known issue
dotnet/core#7176
And seems it will never be fixed(build with newer version and run with 6.0.0/6.0.1) without the workaround in 7176
dotnet/wpf#6101 (comment)

@siegfriedpammer Why not <TargetFrameworks>net48;net6</TargetFrameworks>?
I'm worried if the plugins based on .NET Framework can run.

[christophwille]

No, old plugins won't run. Simply because we are also rearchitecting a few things (major version number).

[siegfriedpammer]

Yes, we are moving a lot of stuff around simply to make code-sharing (or feature-sharing) a lot easier for ILSpy, ilspycmd, ILSpyAvalonia and other flavors of ILSpy. The decompiler engine will probably not see as many breaking changes, but the ILSpy APIs get a much needed makeover after many years of almost no refactorings/clean-up. In its core ILSpy is still the same as it was 11 years ago, when we quickly threw together something to get the decompiler shipped after Red Gate's famous statement concerning Reflector.
