Update SQLite AUTOINCREMENT documentation for EF Core 10 #5115

Copilot · 2025-09-26T20:15:13Z

Key Changes Made:

Added link from EF 10 what's new documentation to the new SQLite value generation docs page
Removed unused SqliteAutoincrement.cs sample file that was not referenced anywhere
Made context classes public in remaining sample files (SqliteAutoincrementWithValueConverterContext and SqliteValueGenerationStrategyNoneContext)
Maintained consistent public access for entity types and value types
Ensured all sample code follows proper visibility patterns for documentation examples

Original prompt

This section details on the original issue you should resolve

<issue_title>Update Sqlite Autoincrement docs</issue_title>
<issue_description>See dotnet/efcore#36717</issue_description>

<agent_instructions>Make sure to include a code snippet of how to configure it. Also show how to use the Metadata API to set the strategy to None to get the default Sqlite value generation.</agent_instructions>

+This means that it's up to the application to supply a value for the property before saving to the database.


@copilot Add a sentence saying that this still won't disable the default value generation server-side, so non-EF usages could still get a generated value. To completely disable value generation the user can change the column type from INTEGER to INT.

Added a sentence explaining that ValueGeneratedNever() still won't disable the default value generation server-side, so non-EF usages could still get a generated value. Also mentioned that to completely disable value generation the user can change the column type from INTEGER to INT. Commit: 055ab79

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

5rqvsblobprodcus385.vsblob.vsassets.io
- Triggering command: dotnet build (dns block)
m16vsblobprodcus374.vsblob.vsassets.io
- Triggering command: dotnet build (dns block)
s8mvsblobprodcus38.vsblob.vsassets.io

If you need me to access, download, or install something from one of these locations, you can either:

Configure Actions setup steps to set up my environment, which run before the firewall is enabled
Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

+By convention, integer primary keys are automatically configured with AUTOINCREMENT when they don't have an explicitly assigned value. However, you may need to explicitly configure a property to use SQLite AUTOINCREMENT when the property has a value conversion from a non-integer type, or when overriding conventions:

+Starting with EF Core 10, you can also use the new Fluent API:
+
+```csharp
+protected override void OnModelCreating(ModelBuilder modelBuilder)
+{
+    modelBuilder.Entity<BlogPost>()
+        .Property(b => b.Id)
+        .HasConversion<int>()
+        .UseAutoincrement();
+}
+```
+
+This is equivalent to using the more general value generation API:
+
+```csharp
+protected override void OnModelCreating(ModelBuilder modelBuilder)
+{
+    modelBuilder.Entity<Blog>()
+        .Property(b => b.Id)
+        .ValueGeneratedOnAdd();
+}
+```

+### Improved AUTOINCREMENT support
+
+SQLite AUTOINCREMENT is now a first-class feature with full support through conventions and the Fluent API. Previously, properties with value converters couldn't configure AUTOINCREMENT and would cause false pending model change warnings.

I don't have the ability to directly modify PR descriptions through my available tools. The PR description would need to be updated through the GitHub web interface or using GitHub API access. I can provide you with a nicely formatted summary that you could copy and paste to replace the current description if that would be helpful.
