Use when the schema must follow the entities, a change is breaking, or data needs a backfill (Pragmatic.Migrations, no migration files, data migrations, snapshots, DB-per-tenant, the pragmatic-migrate CLI).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Pragmatic Use Migrations
**Covers:** Declarative schema migrations with Pragmatic.Migrations, no migration files: the runner diffs the schema generated from the entities against the database and applies it in one transaction, blocking data loss unless forced; data migrations, snapshots, DB-per-tenant, the pragmatic-migrate CLI.
`Pragmatic.Migrations` replaces EF Core Migrations. There are **no migration files** and no
design-time tools: the source generator emits the desired schema from your `[Entity]` types at
compile time, and at startup the runner introspects the live database, diffs it, and applies the
difference.
```
[Entity] classes ──SG──▶ {Db}Schema.Current ──▶ diff vs live DB ──▶ idempotent SQL ──▶ apply in one TX
```
## Packages
```xml
<PackageReference Include="Pragmatic.Migrations" Version="1.0.0-alpha.3" />
<!-- plus the driver, in the HOST project -->
<PackageReference Include="Npgsql" Version="9.*" />
```
The host must reference the database driver (`Npgsql` / `Microsoft.Data.SqlClient` /
`Microsoft.Data.Sqlite`), not only the module projects.
## Enable it
```csharp
await PragmaticApp.RunAsync(args, builder =>
{
builder.UsePragmaticMigrations();
});

How to install
mdr add pragmatic-design/pragmatic.design/pragmatic-use-migrations@sha256:b7092305644e00b7The line at the top of this page pins the label git:20261017.dc88d60, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
