# PassKey Support Test for Pomelo.EntityFrameworkCore.MySql
2+
3+
## Overview
4+
5+
This sample project tests the support for .NET 10 ASP.NET Core Identity PassKeys with Pomelo.EntityFrameworkCore.MySql.
6+
7+
## Background
8+
9+
ASP.NET Core Identity in .NET 10 introduced PassKey support (WebAuthn credentials) as part of the Identity Schema Version 3. The PassKey implementation requires the `IdentityUserPasskey<TKey>` entity, which contains an `IdentityPasskeyData` property that must be stored as JSON using EF Core's `.ToJson()` method.
10+
11+
The `IdentityPasskeyData` class contains properties with non-primitive types, specifically `string[]` (the `Transports` property), which was reported as not working with MySQL providers in [dotnet/aspnetcore#64939](https://github.com/dotnet/aspnetcore/issues/64939).
12+
13+
## Test Results
14+
15+
✅ **All tests passed successfully!**
16+
17+
### What was tested:
18+
19+
1. **Database Creation**: The PassKey table (`AspNetUserPasskeys`) was created successfully
20+
2. **Column Type**: The `Data` column was created as `longtext` (MariaDB's JSON implementation)
21+
3. **Insert Operation**: PassKey records with complex data including `string[]` arrays were inserted successfully
22+
4. **Read Operation**: PassKey records were retrieved correctly with all data intact
23+
5. **Array Handling**: The `string[] Transports` property was correctly serialized to JSON and deserialized back
24+
6. **JSON Validation**: The stored JSON data is valid and can be queried using MariaDB's JSON functions
25+
26+
### Example Output:
27+
28+
```
29+
=== Testing PassKey Support with Pomelo EF Core MySQL ===
30+
31+
1. Testing database connection...
32+
✓ Deleted existing database (if any)
33+
34+
2. Creating database with Identity schema including PassKeys (Version 3)...
35+
✓ Database created successfully!
36+
37+
3. Checking if AspNetUserPasskeys table was created...
38+
✓ AspNetUserPasskeys table exists!
39+
40+
4. Checking Data column type in AspNetUserPasskeys...
41+
✓ Column: Data, Type: longtext, Full Type: longtext
42+
43+
5. Testing insert of a PassKey record with complex data...
44+
✓ Created test user: testuser@example.com
45+
✓ PassKey record inserted successfully!
46+
47+
6. Reading back the PassKey record...
48+
✓ Retrieved PassKey: dGVzdC1jcmVkZW50aWFsLWlkLTEyMzQ1
49+
✓ Name: Test PassKey
50+
✓ SignCount: 0
51+
✓ Transports: [usb, nfc, ble]
52+
✓ Transport count: 3
53+
✓ Transports array correctly stored and retrieved!
54+
55+
7. Checking raw JSON data in database...
56+
Raw JSON in database:
57+
{"AttestationObject":"...", "ClientDataJson":"...", "Transports":["usb","nfc","ble"], ...}
58+
59+
=== ✓ ALL TESTS PASSED! ===
60+
```
61+
62+
## Conclusion
63+
64+
**Pomelo.EntityFrameworkCore.MySql successfully supports .NET 10 Identity PassKeys!**
65+
66+
The `ToJson()` method correctly handles complex types including `string[]` arrays. The implementation uses `MySqlStructuralJsonTypeMapping` which properly converts between MySQL's JSON storage (as longtext) and EF Core's `MemoryStream` representation.
67+
68+
## How to Use PassKeys with Pomelo
69+
70+
To use PassKeys with Pomelo.EntityFrameworkCore.MySql:
71+
72+
1. **Configure your DbContext** to inherit from `IdentityDbContext` with the PassKey type:
73+
74+
```csharp
75+
public class ApplicationDbContext : IdentityDbContext<
76+
IdentityUser,
77+
IdentityRole,
78+
string,
79+
IdentityUserClaim<string>,
80+
IdentityUserRole<string>,
81+
IdentityUserLogin<string>,
82+
IdentityRoleClaim<string>,
83+
IdentityUserToken<string>,
84+
IdentityUserPasskey<string>>
85+
{
86+
// ...
87+
}
88+
```
89+
90+
2. **Configure the PassKey entity** in `OnModelCreating`:
91+
92+
```csharp
93+
protected override void OnModelCreating(ModelBuilder builder)
94+
{
95+
base.OnModelCreating(builder);
96+
97+
builder.Entity<IdentityUserPasskey<string>>(b =>
98+
{
99+
b.HasKey(p => p.CredentialId);
100+
b.ToTable("AspNetUserPasskeys");
101+
b.Property(p => p.CredentialId).HasMaxLength(1024);
102+
b.OwnsOne(p => p.Data).ToJson(); // This is the key configuration!
103+
});
104+
}
105+
```
106+
107+
3. **Use Pomelo as your database provider**:
108+
109+
```csharp
110+
services.AddDbContext<ApplicationDbContext>(options =>
111+
options.UseMySql(connectionString, serverVersion)
112+
);
113+
```
114+
115+
## Running This Test
116+
117+
1. Ensure MariaDB 11.6.2 (or MySQL 8.0+) is running:
118+
```bash
119+
docker run --name mariadb_test -e MYSQL_ROOT_PASSWORD=Password12! -p 127.0.0.1:3306:3306 -d mariadb:11.6.2
120+
```
121+
122+
2. Build and run the test:
123+
```bash
124+
cd samples/PassKeyTest
125+
dotnet run
126+
```
127+
128+
## Technical Details
129+
130+
### JSON Type Mapping
131+
132+
- **Storage**: MariaDB stores JSON as `longtext` with JSON validation constraints
133+
- **Serialization**: Pomelo uses `MySqlStructuralJsonTypeMapping` to handle JSON columns
134+
- **Reader/Writer**: The implementation reads strings from the database and converts them to `MemoryStream` for EF Core's JSON handling
135+
- **Arrays**: Non-primitive types like `string[]` are correctly serialized/deserialized as JSON arrays
136+
137+
### Tested With
138+
139+
- .NET 10.0.101
140+
- Pomelo.EntityFrameworkCore.MySql (current version)
141+
- Microsoft.AspNetCore.Identity.EntityFrameworkCore 10.0.1
142+
- MariaDB 11.6.2
143+
- MySqlConnector 2.5.0
