Hey @Maximilien_Selva You’re using UiPath.Mail.Activities which internally depends on System.Text.Json >= 5.0.2
System.Memory.Data, coming from a dependency chain via Azure.Core, requires System.Text.Json >= 6.0.0
Your project ends up using version 5.0.2, and you’re getting a NU1605 warning because a downgrade was detected one part of your dependency graph needs 6.0.0 but another only brings in 5.0.2, so the lower version is selected.
NuGet uses the lowest version that satisfies all dependencies, unless explicitly overridden.
In your case, System.Text.Json 5.0.2 is being used, because it’s the version resolved from the host feed, and it’s the minimum version that satisfies the lowest dependent package.
The warning NU1605 indicates this could cause runtime issues, especially if System.Memory.Data uses features from System.Text.Json 6.0.0 that don’t exist in 5.0.2.
cheers
