Negating method group in LINQ

[michalczerwinski]

Currently I can use method group instead of full lambda for parameters. For example this:

s.Where(s => s.IsDigit(s));

can be shortened to

s.Where(IsDigit);

Unfortunately it doesn't work for negated variant:

s.Where(!IsDigit);

Correct. The language does not support that. You can open discussions (not issues) on this at dotnet/csharplang.

Thanks!
