@ankane, following your preference in #63, this prepares Pgvector.EntityFrameworkCore 0.4.0-rc.1 for .NET 11 and EF Core 11, including the convention to stop auto-loading vector columns. This is a release candidate because EF Core 11 has not yet been released.

Closes #59

Summary

• Set Pgvector.EntityFrameworkCore to version 0.4.0-rc.1, targeting net11.0 only, with Npgsql.EntityFrameworkCore.PostgreSQL 11.0.0-rc.1.1.
• Register an IConventionSetPlugin using EF 11's AutoLoadConvention to exclude Vector, HalfVector, and SparseVector properties from automatic entity loading by default. Explicit model configuration takes precedence; BitArray behavior is unchanged.
• Move design-time registration targets to build/net11.0, update the SDK/CI configuration, and document explicit projections and model-level opt-in via Metadata.IsAutoLoaded = true.
• Cover generated SQL, tracked/untracked materialization, vector filtering/ordering and distance queries, explicit projections, preservation of unloaded vectors during unrelated updates, and explicit auto-loading overrides.

Rebased directly onto the latest upstream master. This PR no longer depends on #63 and does not include the proposed EF 10 release. For EF Core 9 and 10, the README continues to recommend version 0.3.0.

Lower-level Pgvector and Pgvector.Dapper versions, target frameworks, and dependency policies are unchanged. Per-query auto-loading opt-in is out of scope.

Validation

• All 18 focused EF tests passed after rebasing against local PostgreSQL 18.4 using .NET SDK 11.0.100-rc.2.26504.105.
• Packed Pgvector.EntityFrameworkCore.0.4.0-rc.1.nupkg successfully; verified version 0.4.0-rc.1, the EFCore.PG 11 dependency, and only lib/net11.0 and build/net11.0 assets.
• An isolated package consumer verified the convention, generated design-time services reference, and design-time mapping/code-generation registration.

No packages were published.

@ankane as discussed in #63, here's the PR updating to version 0.4.0-rc.1, and taking a dependency on EF and EFCore.PG 11.0.0.

[ankane]

Thanks @roji! Merged in the two commits above (one to support IsAutoLoaded and the other to change the default value).

[ankane]

Also, fwiw, EF Core doesn't set the properties even when the query returns them (which doesn't seem great).

var items = await ctx.Items.FromSql($"SELECT * FROM efcore_items ORDER BY embedding <-> {embedding} LIMIT 5").ToListAsync();
Assert.Null(items[0].Embedding);

Thanks!

Yeah, that seems like a bug on the EF Side - opened dotnet/efcore#39398.

[ankane]

Awesome, thanks!
