Assembly Version Conflict: Targeted net8.0-ios17.2 Project Fails with Microsoft.iOS, Version=18.0.0.0 Dependency Mismatch

**Description:** I am encountering a version conflict when targeting net8.0-ios17.2 in my project. The problem arises when creating NuGet packages on a machine with the latest .NET SDK. The package appears to automatically target Microsoft.iOS, Version=18.0.0.0, despite specifying net8.0-ios17.2 in the project file.

When I add this package to a project and attempt to build it on another machine without the latest .NET SDK, I receive the following error:

`Error: Assembly uses 'Microsoft.iOS, Version=18.0.0.0', which has a higher version than referenced assembly 'Microsoft.iOS' with identity 'Microsoft.iOS, Version=17.2.0.0'
`

**Expected Behavior:** The project should build successfully with when targeting net8.0-ios17.2, without triggering a conflict with Microsoft.iOS, Version=18.0.0.0.

**Actual Behavior:** The build fails due to a version mismatch, as the assembly version defaults to Microsoft.iOS, Version=18.0.0.0, rather than respecting the specified target of 17.2.0.0 in the .csproj file.

**Steps to reproduce:**

1. On a machine with the latest .NET SDK, create a NuGet package targeting net8.0-ios17.2.
2. Add this package to a project on another machine that does not have the latest .NET SDK.
3. Ensure the project’s .csproj file explicitly targets net8.0-ios17.2.
4. Build the project and observe the version conflict error in the output.
