Upgrading from 4.0.1 to 4.1.1 - Conditional Target Frameworks

[mwasson74]

After upgrading from 4.0.1 to 4.1.1, the compiler (?) is now choosing the Null extension method where the parameterName parameter is required instead of the definition where parameterName is optional.

4.0.1:

4.1.1:

What am I doing wrong here?

I changed my project from targeting .NET 6 to target .NET 7 and it now chooses the correct method definition. I wouldn't think that I would need to change my target version when the else branch of the if-statement should still apply.

We have not committed to targeting .NET 7 yet because .NET 6 is the LTS version. Please advise.

Yeah that's weird and unexpected. Maybe the problem (for you, at least) goes away in a couple of months when .NET 8 is LTS... :)

I'll see if I can repro the issue and work out a fix. I've updated a bunch of my projects, some net6 some net7, and haven't seen this.

@ardalis were you able to see if you can reproduce this?

[mwasson74]

@ardalis is my question now closed due to the fix on #303??

[ardalis]

I'm hoping so, yes. Can you confirm the latest bits are working as you expect?

[mwasson74]

Yep, now working as expected!! Thank you!!
