When to Use

  • Writing C# or .NET code connecting to Neo4j
  • Setting up IDriver, DI registration, or session/transaction lifecycle
  • Questions about ExecutableQuery, IResultCursor, async patterns, result mapping
  • Debugging sessions, type mapping, null safety, or error handling in .NET

When NOT to Use

  • Writing/optimizing Cypher queries → neo4j-cypher-skill
  • Upgrading from older driver version → neo4j-migration-skill

Driver Lifecycle

IDriver — thread-safe, connection-pooled, expensive to create. Create one per application.

using Neo4j.Driver;

// URI schemes:
//   neo4j+s://xxx.databases.neo4j.io   — TLS + cluster routing (Aura)
//   neo4j://localhost                   — unencrypted + cluster routing
//   bolt+s://localhost:7687             — TLS + single instance
//   bolt://localhost:7687               — unencrypted + single instance

await using var driver = GraphDatabase.Driver(
    "neo4j+s://xxx.databases.neo4j.io",
    AuthTokens.Basic("neo4j", "password"));

await driver.VerifyConnectivityAsync();   // fail fast on startup

IDriver and IAsyncSession implement IAsyncDisposable — always await using, never plain using.

// ❌ Wrong — synchronous Dispose() may block thread pool
using var driver = GraphDatabase.Driver(uri, auth);

// ✅ Correct
await using var driver = GraphDatabase.Driver(uri, auth);

Auth options: AuthTokens.Basic(u, p) / AuthTokens.Bearer(token) / AuthTokens.Kerberos(ticket) / AuthTokens.None

Environment Variables

Load connection config from environment / appsettings.json — never hardcode credentials.

// appsettings.json
{
  "Neo4j": {
    "Uri": "neo4j+s://xxx.databases.neo4j.io",
    "User": "neo4j",
    "Password": "secret",
    "Database": "neo4j"
  }
}

// Access via IConfiguration (injected in Program.cs)
var uri      = builder.Configuration["Neo4j:Uri"];
var user     = builder.Configuration["Neo4j:User"];
var password = builder.Configuration["Neo4j:Password"];
var database = builder.Configuration["Neo4j:Database"] ?? "neo4j";

Override with environment variables (standard .NET behavior): Neo4j__Uri=neo4j+s://... (double underscore = colon separator). Never commit appsettings.json with real credentials — use appsettings.Development.json (gitignored) or env vars in CI/production.

DI Registration (ASP.NET Core)

Register IDriver as singleton — never Scoped or Transient. Never register IAsyncSession in DI.

// Program.cs
builder.Services.AddSingleton<IDriver>(_ =>
    GraphDatabase.Driver(
        builder.Configuration["Neo4j:Uri"],
        AuthTokens.Basic(
            builder.Configuration["Neo4j:User"],
            builder.Configuration["Neo4j:Password"])));

// Shutdown hook — dispose the singleton cleanly
builder.Services.AddHostedService<Neo4jShutdownService>();

// Neo4jShutdownService.cs
public class Neo4jShutdownService(IDriver driver, IHostApplicationLifetime lifetime)
    : IHostedService
{
    public Task StartAsync(CancellationToken _)
    {
        lifetime.ApplicationStopping.Register(() =>
            driver.DisposeAsync().AsTask().GetAwaiter().GetResult());
        return Task.CompletedTask;
    }
    public Task StopAsync(CancellationToken _) => Task.CompletedTask;
}

// Inject into services — sessions opened per unit of work
public class PersonService(IDriver driver)
{
    public async Task<List<string>> GetNamesAsync(CancellationToken ct = default)
    {
        var (records, _, _) = await driver
            .ExecutableQuery("MATCH (p:Person) RETURN p.name AS name")
            .WithConfig(new QueryConfig(database: "neo4j"))
            .ExecuteAsync(ct);
        return records.Select(r => r.Get<string>("name")).ToList();
    }
}

Choose the Right API

session.RunAsync()LOAD CSV, CALL {} IN TRANSACTIONS❌✅
session.BeginTransactionAsync()Multi-function, external coordination❌✅

ExecutableQuery — Recommended Default

Fluent builder; manages session, transaction, retries, and bookmarks automatically.

// Read
var (records, summary, keys) = await driver
    .ExecutableQuery("MATCH (p:Person {name: $name})-[:KNOWS]->(f) RETURN f.name AS name")
    .WithParameters(new { name = "Alice" })
    .WithConfig(new QueryConfig(
        database: "neo4j",
        routing: RoutingControl.Readers))    // route reads to replicas
    .ExecuteAsync(cancellationToken);

foreach (var r in records)
    Console.WriteLine(r.Get<string>("name"));

// Use ResultConsumedAfter for wall-clock timing (ResultAvailableAfter = time-to-first-byte only)
Console.WriteLine($"{summary.ResultConsumedAfter.TotalMilliseconds} ms");

// Write
var (_, writeSummary, _) = await driver
    .ExecutableQuery("CREATE (p:Person {name: $name, age: $age})")
    .WithParameters(new { name = "Bob", age = 30 })
    .WithConfig(new QueryConfig(database: "neo4j"))
    .ExecuteAsync();
Console.WriteLine($"Created {writeSummary.Counters.NodesCreated} nodes");

// WithMap — project inline
var names = await driver
    .ExecutableQuery("MATCH (p:Person) RETURN p.name AS name")
    .WithConfig(new QueryConfig(database: "neo4j"))
    .WithMap(r => r["name"].As<string>())
    .ExecuteAsync();   // names.Result is IReadOnlyList<string>

Never await omitted: ExecuteAsync() returns Task — missing await compiles silently but query never runs.

Never string-interpolate Cypher. Always WithParameters() — prevents injection, enables plan caching.

Managed Transactions

Use for large result sets (lazy streaming) or multiple queries per transaction. Callback auto-retried on transient failure — keep it idempotent, no side effects inside.

await using var session = driver.AsyncSession(conf => conf.WithDatabase("neo4j"));

// Read — routes to replicas
var names = await session.ExecuteReadAsync(async tx =>
{
    var cursor = await tx.RunAsync(
        "MATCH (p:Person) WHERE p.name STARTS WITH $prefix RETURN p.name AS name",
        new { prefix = "Al" });
    return await cursor.ToListAsync(r => r.Get<string>("name"));
    // Consume cursor INSIDE callback — invalid after callback returns
});

// Write — void, no async needed
await session.ExecuteWriteAsync(tx =>
    tx.RunAsync("MERGE (p:Person {name: $name})", new { name = "Carol" }));

// Write — async when needing counters
var summary = await session.ExecuteWriteAsync(async tx =>
{
    var cursor = await tx.RunAsync(
        "CREATE (p:Person {name: $name})", new { name = "Alice" });
    return await cursor.ConsumeAsync();   // drains cursor, returns IResultSummary
});
Console.WriteLine($"Created {summary.Counters.NodesCreated} nodes");

Cursor rules:

  • Consume with ToListAsync() or FetchAsync() loop inside the callback
  • Returning a cursor from the callback → transaction closes → cursor invalid → exception
// ❌ Returns cursor — tx closes immediately after lambda returns
var cursor = await session.ExecuteReadAsync(async tx =>
    await tx.RunAsync("MATCH (p:Person) RETURN p.name AS name"));
await cursor.FetchAsync();   // throws

// ✅ Consume inside
var names = await session.ExecuteReadAsync(async tx =>
{
    var cursor = await tx.RunAsync("MATCH (p:Person) RETURN p.name AS name");
    return await cursor.ToListAsync(r => r.Get<string>("name"));
});

Async void trap:

// ❌ CS1998 warning — async with no await; RunAsync Task discarded
await session.ExecuteWriteAsync(async tx =>
    tx.RunAsync("MERGE (p:Person {name: $name})", new { name = "Alice" }));

// ✅ No async, return Task directly
await session.ExecuteWriteAsync(tx =>
    tx.RunAsync("MERGE (p:Person {name: $name})", new { name = "Alice" }));

FetchAsync Loop

var cursor = await tx.RunAsync("MATCH (p:Person) RETURN p.name AS name");

while (await cursor.FetchAsync())          // true while records remain
{
    Process(cursor.Current.Get<string>("name"));
}
// Do NOT use cursor.Current after the loop — it holds the last record, not null
// Do NOT call FetchAsync() again after it returned false — throws InvalidOperationException

Cursor consumption methods:

MethodRecordsSummaryUse
ToListAsync()✅ all❌Need records
ToListAsync(mapper)✅ mapped❌Need mapped records
FetchAsync() loop✅ one/time❌ until ConsumeAsyncLarge/lazy
ConsumeAsync()❌ discards✅Need counters

IResultSummary profiling [v6.3.0+]: summary.Profile is [Obsolete] → use summary.QueryProfile (IQueryProfile), whose DbHits, Rows, Time, PageCacheHits, PageCacheMisses are long? — null means not recorded, distinct from 0. Gate on summary.HasProfile. | SingleAsync() | ✅ exactly 1 | ❌ | Expect one row |

Record Value Access

// Two equivalent patterns — prefer .Get<T>()
string name = record.Get<string>("name");
int    age  = record.Get<int>("age");

string name2 = record["name"].As<string>();   // indexer + As<T>
string name3 = record[0].As<string>();        // by column index

// Null safety — .As<T>() on null graph value throws InvalidCastException
string? city = record["city"].As<string?>();  // ✅ nullable
int?    age2 = record["age"].As<int?>();      // ✅ nullable

// Absent key — throws KeyNotFoundException (typo or not in RETURN)
if (record.Keys.Contains("city"))
    var city3 = record.Get<string?>("city");

## When to Use
- Writing C# or .NET code connecting to Neo4j
- Setting up `IDriver`, DI registration, or session/transaction lifecycle
- Questions about `ExecutableQuery`, `IResultCursor`, async patterns, result mapping
- Debugging sessions, type mapping, null safety, or error handling in .NET

## When NOT to Use
- **Writing/optimizing Cypher queries** → `neo4j-cypher-skill`
- **Upgrading from older driver version** → `neo4j-migration-skill`

---

## Install

```bash
dotnet add package Neo4j.Driver
```

| Package | Use |
|---|---|
| `Neo4j.Driver` | Async API — **use this** |
| `Neo4j.Driver.Simple` | Synchronous wrapper |
| `Neo4j.Driver.Reactive` | System.Reactive streams |

## Driver Lifecycle

`IDriver` — thread-safe, connection-pooled, expensive to create. **Create one per application.**

```csharp
using Neo4j.Driver;

// URI schemes:
//   neo4j+s://xxx.databases.neo4j.io   — TLS + cluster routing (Aura)
//   neo4j://localhost                   — unencrypted + cluster routing
//   bolt+s://localhost:7687             — TLS + single instance
//   bolt://localhost:7687               — unencrypted + single instance

await using var driver = GraphDatabase.Driver(
    "neo4j+s://xxx.databases.neo4j.io",
    AuthTokens.Basic("neo4j", "password"));

await driver.VerifyConnectivityAsync();   // fail fast on startup
```

`IDriver` and `IAsyncSession` implement `IAsyncDisposable` — always `await using`, never plain `using`.

```csharp
// ❌ Wrong — synchronous Dispose() may block thread pool
using var driver = GraphDatabase.Driver(uri, auth);

// ✅ Correct
await using var driver = GraphDatabase.Driver(uri, auth);
```

Auth options: `AuthTokens.Basic(u, p)` / `AuthTokens.Bearer(token)` / `AuthTokens.Kerberos(ticket)` / `AuthTokens.None`

## Choose the Right API

| API | When | Auto-retry | Streaming |
|---|---|---|---|
| `driver.ExecutableQuery()` | Most queries — simple default | ✅ | ❌ eager |
| `session.ExecuteReadAsync/WriteAsync()` | Large results, multi-query tx | ✅ | ✅ |
| `session.RunAsync()` | `LOAD CSV`, `CALL {} IN TRANSACTIONS` | ❌ | ✅ |
| `session.BeginTransactionAsync()` | Multi-function, external coordination | ❌ | ✅ |

## ExecutableQuery — Recommended Default

Fluent builder; manages session, transaction, retries, and bookmarks automatically.

```csharp
// Read
var (records, summary, keys) = await driver
    .ExecutableQuery("MATCH (p:Person {name: $name})-[:KNOWS]->(f) RETURN f.name AS name")
    .WithParameters(new { name = "Alice" })
    .WithConfig(new QueryConfig(
        database: "neo4j",
        routing: RoutingControl.Readers))    // route reads to replicas
    .ExecuteAsync(cancellationToken);

foreach (var r in records)
    Console.WriteLine(r.Get<string>("name"));

// Use ResultConsumedAfter for wall-clock timing (ResultAvailableAfter = time-to-first-byte only)
Console.WriteLine($"{summary.ResultConsumedAfter.TotalMilliseconds} ms");

// Write
var (_, writeSummary, _) = await driver
    .ExecutableQuery("CREATE (p:Person {name: $name, age: $age})")
    .WithParameters(new { name = "Bob", age = 30 })
    .WithConfig(new QueryConfig(database: "neo4j"))
    .ExecuteAsync();
Console.WriteLine($"Created {writeSummary.Counters.NodesCreated} nodes");

// WithMap — project inline
var names = await driver
    .ExecutableQuery("MATCH (p:Person) RETURN p.name AS name")
    .WithConfig(new QueryConfig(database: "neo4j"))
    .WithMap(r => r["name"].As<string>())
    .ExecuteAsync();   // names.Result is IReadOnlyList<string>
```

Never `await` omitted: `ExecuteAsync()` returns `Task` — missing `await` compiles silently but query never runs.

Never string-interpolate Cypher. Always `WithParameters()` — prevents injection, enables plan caching.

        "MATCH (p:Person) WHERE p.name STARTS WITH $prefix RETURN p.name AS name",
        new { prefix = "Al" });
    return await cursor.ToListAsync(r => r.Get<string>("name"));
    // Consume cursor INSIDE callback — invalid after callback returns
});

// Write — void, no async needed
await session.ExecuteWriteAsync(tx =>
    tx.RunAsync("MERGE (p:Person {name: $name})", new { name = "Carol" }));

// Write — async when needing counters
var summary = await session.ExecuteWriteAsync(async tx =>

- Consume with `ToListAsync()` or `FetchAsync()` loop **inside** the callback
- Returning a cursor from the callback → transaction closes → cursor invalid → exception

```csharp
// ❌ Returns cursor — tx closes immediately after lambda returns

}
// Do NOT use cursor.Current after the loop — it holds the last record, not null
// Do NOT call FetchAsync() again after it returned false — throws InvalidOperationException
```

Cursor consumption methods:

  • Dependency or permission surface needs review
  • Permission surface may require sandboxing
  • Financial research output is not financial advice; require human review before any live investment decision
  • The skill is purely informational and poses no security risk; however, it includes executable code examples that, if copied verbatim, could expose credentials if not handled properly (mitigated by strong best-practice guidance).
  • The 'allowed-tools' include Bash and WebFetch, which could be used for unintended actions if the agent is not properly sandboxed, but the skill itself contains no instructions for executing arbitrary commands beyond standard development practices.
  • Financial research output is not financial advice; require human review before any live investment decision.
  • Quality score needs review
  • Permission surface needs review: secrets or environment access, shell or command execution
  • Stars/forks activity: 101 stars, 35 forks; issue activity unavailable in current metadata
  • Dependency/runtime risk: command execution surface, credential or environment access
