New DLL not included in Build?

[rozeboosje]

We have a solution targeting .NET Framework 4.8 and we are always very careful to keep the nuget packages we use up to date.

Today I upgraded the Microsoft.Data.SqlClient package to 6.1.4 and while it was installing I noticed that it added a new dependency to System.Text.RegularExpressions 4.3.1

After the build, however, I don't see a System.Text.RegularExpressions.dll in the output folder.

Is this an omission? Is there any cause for concern? Or is this expected behaviour and nothing to worry about?

@rozeboosje Thanks for upgrading to 6.1.4!
In 6.1.4 we added a NuGet dependency on System.Text.RegularExpressions (4.3.1) through #3843 .
For projects targeting .NET Framework 4.8, it’s expected that you won’t see a System.Text.RegularExpressions.dll copied to the output folder, because regex support is already included with .NET Framework and is resolved from the framework/GAC at runtime.
So, this isn’t an omission and shouldn’t be a concern. @paulmedynski, can you confirm if this is correct?

@rozeboosje, if you face any issues after updating to 6.1.4, do let us know and we will investigate. Thanks.

Thank you for the clarification. I ran the software after rebuilding and all seems well. Having said that, we do not use any regular expressions related functionality through SqlClient so I cannot be certain that this proves all is well, but suffice to say it doesn't impact us so we're happy enough. I'd love to hear from @paulmedynski for additional reassurance but I'm happy to proceed with the package as it currently stands.

Adding @mdaigle @David-Engel for their inputs on this issue.

Confirming @apoorvdeshmukh's statement above.

So, this isn’t an omission and shouldn’t be a concern.

Closing this as a no-op.
