Greptile Summary

This PR upgrades the Appwrite .NET SDK from v5.1.0 to v6.0.0, aligning it with new server-side APIs. The changes are largely auto-generated and follow consistent SDK patterns already established in the codebase.

• Breaking removals: Health and Usage services (plus their models/enums) are deleted; spatial attribute default parameter types are tightened from List<object> to typed coordinate lists; ActivityEvent loses OS/client/device/country detail fields.
• New additions: Organization service with CRUD and membership methods; Client.SetBearer for OAuth Bearer authentication (correctly prefixes Bearer ); vector query helpers (VectorDot, VectorCosine, VectorEuclidean); billing plan models and enums; geolocation/ISP fields on Locale.
• Dependency bump: System.Text.Json updated from 9.0.5 to 9.0.17 alongside the version bump to 6.0.0.

Confidence Score: 5/5

All breaking changes are intentional and documented in CHANGELOG; new code follows established SDK patterns with no logic errors found.

The diff is auto-generated SDK code. Breaking changes (Health/Usage removal, field removals, type narrowing) are all explicitly called out in the CHANGELOG. The new SetBearer method correctly includes the "Bearer " scheme prefix. No missing null guards, incorrect conversions, or mismatched API paths were identified in the changed paths.

No files require special attention; the previously flagged Program model naming issue is tracked in an existing review thread.

Important Files Changed

Filename	Overview
Appwrite/Client.cs	Added SetBearer method with correct "Bearer " prefix, bumped version strings to 6.0.0, shortened impersonation XML doc summaries.
Appwrite/Appwrite.csproj	Version bumped to 6.0.0; System.Text.Json dependency updated from 9.0.5 to 9.0.17.
Appwrite/Query.cs	Added VectorDot, VectorCosine, and VectorEuclidean query helpers following existing patterns.
Appwrite/Models/Organization.cs	New model for the Organization entity with billing fields; billingLimits is correctly handled as optional.
Appwrite/Models/BillingPlan.cs	New model with 68-parameter constructor; references Appwrite.Models.Program which has a known naming collision risk (flagged in prior review).
Appwrite/Models/Program.cs	New model named Program; naming conflict with .NET implicit entry-point class was flagged in a prior review thread.
Appwrite/Models/ActivityEvent.cs	Removed OS, client, device, countryCode, and countryName fields as a documented breaking change.
Appwrite/Services/Organization.cs	Added Get, Update, Delete, and membership CRUD methods for the Organization service.
Appwrite/Services/Health.cs	Deleted entirely as a breaking change; documented in CHANGELOG.
Appwrite/Services/Usage.cs	Deleted entirely as a breaking change; documented in CHANGELOG.

Program conflicts with .NET entry-point class name

Naming a model class Program inside the Appwrite.Models namespace can cause confusing compiler errors for users whose top-level Program class is in the global namespace or in a project that imports Appwrite.Models with a using directive. .NET's implicit Program entry-point class (C# 9+ top-level statements) is also unqualified, so any file that does using Appwrite.Models; and then references Program will see an ambiguity error. Consider renaming to BillingProgram or ProgramDetails to avoid the collision.

Comment:
**`Program` conflicts with .NET entry-point class name**

Naming a model class `Program` inside the `Appwrite.Models` namespace can cause confusing compiler errors for users whose top-level `Program` class is in the global namespace or in a project that imports `Appwrite.Models` with a `using` directive. .NET's implicit `Program` entry-point class (C# 9+ top-level statements) is also unqualified, so any file that does `using Appwrite.Models;` and then references `Program` will see an ambiguity error. Consider renaming to `BillingProgram` or `ProgramDetails` to avoid the collision.
