📝 Summary

Summary by CodeRabbit

• Compatibility
  • Updated the networking package’s runtime compatibility requirement to include the System.Net native contract. Targets must provide this contract to use the package.
  • Aligned the package and its related test projects with nanoFramework Core Library preview 63.

Walkthrough

System.Net and five test projects now use nanoFramework.CoreLibrary preview 63 instead of preview 52. The System.Net package metadata now identifies its native contract hash, and the assembly native version attribute was removed.

Changes

CoreLibrary and package metadata update

Layer / File(s)	Summary
System.Net package metadata and dependency nanoFramework.System.Net.nuspec, nanoFramework.System.Net/Properties/AssemblyInfo.cs, nanoFramework.System.Net/System.Net.nfproj, nanoFramework.System.Net/packages.*	The package metadata now identifies the System.Net native contract hash. The assembly native version attribute was removed. The project and package records now use CoreLibrary preview 63.
Test project dependencies Tests/IPAddressTests/*, Tests/NetworkHelperTests/*, Tests/SocketTests/*, Tests/SslStreamTests/*, Tests/SslStreamTests_WiFi/*	The test project references and package records now use CoreLibrary preview 63, with updated lockfile hashes.

Merge Risk: ⚪ Minimal · up to d5044

This change updates the CoreLibrary dependency consistently and switches the package metadata to the System.Net native contract hash. Before the package is released, the nf-interpreter native declaration must be updated to the new hash (0x5AD7808D), as noted in the project's tracking issue. That release prerequisite is outside this repository. No code-level merge blocker was found.
