Summary

  • Migrate EFCore.FSharp from .NET 6 / EF Core 6 to .NET 10 / EF Core 10
  • Update all dependencies (FSharp.Core, FSharp.Compiler.Service, paket, fantomas, FAKE)
  • Adapt library and test code to EF Core 10 breaking changes (removed/renamed APIs, new interface members, constructor changes)
  • Add C# interop project for TestRelationalTypeMappingSource (F# cannot handle C# covariant return types)
  • Update CI workflow, devcontainer, VS Code configs, and documentation for .NET 10
  • Replace deprecated PackageLicenseUrl with PackageLicenseExpression (MIT)
  • Relax FSharp.Core dependency constraint to >= 9.0.100

Checklist

  • I have followed the Contribution Guidelines
  • I have added tests (if appropriate)
  • I have added necessary documentation (if appropriate)

Test plan

  • All 84 existing tests pass on all platforms (ubuntu, windows, macOS)
  • Fantomas formatting check passes
  • NuGet package builds correctly with proper metadata (MIT license, net10.0 TFM)
  • End-to-end test: created sample F# project with EF Core migrations (scaffolding, applying, SQLite)
  • Devcontainer Docker image builds successfully
  • CI green on all 3 platforms

EntityFrameworkExtensions:
- NamespaceComparer moved to Microsoft.EntityFrameworkCore.Design
- Remove GetEntityTypeErrors (removed in EF Core 7)

EFCoreFSharpServices:
- ICSharpEntityTypeGenerator/ICSharpDbContextGenerator interfaces
  removed in EF Core 7; register concrete types directly

FSharpHelper (ICSharpHelper interface):
- Fragment: MethodCallCodeFragment -> IMethodCallCodeFragment
- Add Fragment overloads: IMethodCallCodeFragment+indent,
  NestedClosureCodeFragment, PropertyAccessorCodeFragment,
  AttributeCodeFragment
- Add Identifier<T> overload with IDictionary
- Add Lambda(IEnumerable<IProperty>) overload
- Add Literal: DateOnly, TimeOnly, BigInteger, List<T>, Dictionary
- Literal(Enum) gains fullName parameter
- Namespace: add ParamArray attribute
- Add XmlComment, Arguments, GetRequiredUsings, Statement, Expression
- Fix AppendLine(FormattableString) ambiguity with type annotation

FSharpDbContextGenerator:
- ISequence.ClrType -> .Type
- Remove ScaffoldingAnnotationNames.EntityTypeErrors
- Remove GetEntityTypeErrors loop
- Convert ICSharpDbContextGenerator interface to member

FSharpEntityTypeGenerator:
- GetPropertiesAndNavigations -> GetMembers
- Convert ICSharpEntityTypeGenerator interface to member

FSharpModelGenerator:
- Use concrete generator types instead of removed interfaces
- ScaffoldedFile: named-param constructor -> positional constructor

FSharpMigrationsScaffolder:
- Save: add dryRun parameter, guard file writes
- Fix File.WriteAllText ReadOnlySpan<char> overload ambiguity

FSharpSnapshotGenerator:
- Fragment(c, builderName) -> Fragment(c, builderName, false)
  (typeQualified parameter now required)
@techiedesu
Add C# interop project for TestRelationalTypeMappingSource
3662d47 
F# cannot handle C# covariant return types used by
RelationalTypeMappingSource in EF Core 10 (new virtual methods with
sealed bridge methods). The F# compiler doesn't see the bridge methods
as implementing abstract members from TypeMappingSourceBase.

Move TestRelationalTypeMappingSource to a C# project and have the
F# test project reference it. Also update the F# stub to inherit
from the C# base class and fix Clone -> WithStoreTypeAndSize rename.

Mocks.fs:
- Add IHistoryRepository members: Create, CreateAsync,
  LockReleaseBehavior, AcquireDatabaseLock, AcquireDatabaseLockAsync

SqlServerTestHelpers.fs, RelationalTestHelpers.fs:
- UseProviderOptions now returns DbContextOptionsBuilder
  (was void in EF Core 6)

FakeDbConnection.fs:
- Remove AppendIdentityWhereCondition, AppendSelectAffectedCountCommand,
  AppendRowsAffectedWhereCondition (removed from UpdateSqlGenerator)

BuildReference.fs:
- Replace CompileToDynamicAssembly with Compile + Assembly.Load
  (CompileToDynamicAssembly removed in FSharp.Compiler.Service 43)
- Shared FSharpChecker instance with lock for thread safety
