[](https://www.nuget.org/packages/Dorssel.EntityFrameworkCore.Sqlite.Timestamp)
Extension for Entity Framework (EF) Core 8.0 (or higher) that adds support for SQLite row versioning (`[Timestamp]` attribute).
The implementation is for AnyCPU, and works on all platforms.
# Usage
Add a package reference to your project for
[`Dorssel.EntityFrameworkCore.Sqlite.Timestamp`](https://www.nuget.org/packages/Dorssel.EntityFrameworkCore.Sqlite.Timestamp),
next to an explicit reference to the required version of SQLite.
For EF Core 8:
```diff
+
```
For EF Core 9:
```diff
+
```
> [!NOTE]
> It is not recommended to solely rely on the transitive dependency on `Microsoft.EntityFrameworkCore.Sqlite`,
> as that would use the version at the time `Dorssel.EntityFrameworkCore.Sqlite.Timestamp` was built
> instead of the latest one. Therefore, always add an explicit package reference for `Microsoft.EntityFrameworkCore.Sqlite`
> in your project as well.
In your `DbContext` derived class modify the following:
```diff
+ using Dorssel.EntityFrameworkCore;
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder
.UseSqlite($"Data Source={DbPath}")
+ .UseSqliteTimestamp();
}
```
This is all you need to support row versioning with SQLite, including support for migrations.
See [Native database-generated concurrency tokens](https://learn.microsoft.com/en-us/ef/core/saving/concurrency?tabs=data-annotations#native-database-generated-concurrency-tokens);
except now you can ignore the part that says it isn't supported with SQLite!
## Example
See the Example project for a demonstration using .NET 9 & EF Core 9.
