Closes #127

Very cool, big fan of this change!

[MichaelPeter]

Love it

[jdrobison]

Late to the party here, but +1 on the "love it" comments!

Question: this works even when targeting .NET Framework, correct?

[AArnott]

Correct, @jdrobison. The only requirement is that you have a VS 2022 era C# compiler.

Amazing, thank you for changing this!

For anyone now facing a mass migration, the following RegEx might be helpful. In VS's Replace in files:

• Requires\.NotNull\((\w+), nameof\(\1\)\);
• Requires.NotNull($1);

Also:

• Requires.NotNullAllowStructs
• Requires.NotNullOrEmpty
• Requires.NotNullOrWhiteSpace
• Requires.NullOrNotNullElements
• Requires.NotNullEmptyOrNullElements
• Requires.NotEmpty
• Requires.Defined
• Requires.NotDefault

Calls to Assumes.True(bool, string) and Assumes.False(bool, string) likely require manual review.
