2026-09-09 errors ef-core ef-core-11

Fix: AS JSON option can be specified only for column of nvarchar(max) type in WITH clause

EF Core emits [col] json '$.path' AS JSON inside OPENJSON WITH, which Azure SQL rejects with Msg 13618. Upgrade to EF Core 10.0.11+, or drop the provider compatibility level to 160.

Fix: Complex entry original ordinal '-1' is invalid when saving a ToJson complex collection

Upgrade Microsoft.EntityFrameworkCore to 10.0.10 or later. Before that, growing a nested collection under a second ToJson complex property crashed SaveChanges.

2026-09-09 errors ef-core ef-core-11

Fix: The complex type collection must be initialized to a non-null value

On EF Core 10.0.x, nulling a complex property that holds a two-element collection inside a ToJson complex collection breaks DetectChanges. Fixed in 11.0.0-rc.1.

2026-09-08 errors ef-core ef-core-11

Fix: MissingMethodException 'AbstractionsStrings.ArgumentIsEmpty' after upgrading EF Core Tools

dotnet ef throws MissingMethodException on ArgumentIsEmpty because Tools 10.0.6 stopped pulling a matching Microsoft.EntityFrameworkCore.Design. Pin Design explicitly to your EF Core version.

2026-08-31 errors flutter android

Fix: Firebase Auth sign-in does not persist in a Flutter Android release build

Firebase Auth restores the Android session from a private SharedPreferences file with no network call, so a release-only sign-out is never broken persistence. It is a different google-services.json, a rejected token refresh, App Check, or your own catch block.

2026-08-31 errors flutter dart

Fix: The method 'getInvocation' isn't defined for the type 'DartObjectImpl'

build_runner fails to compile because source_gen 3.1.0 or 4.0.0 calls an analyzer API removed in analyzer 8.4.0. Upgrade the generator that pins source_gen below 4.0.1.

2026-08-30 errors ef-core ef-core-11

Fix: 23505: duplicate key value violates unique constraint on a concurrent EF Core insert

The check-then-insert in your handler is not atomic. Catch PostgresException with SqlState 23505, or collapse the whole thing into one INSERT ... ON CONFLICT statement. EnableRetryOnFailure will not help.

2026-08-30 errors ef-core ef-core-11

Fix: CREATE DATABASE permission denied in database 'master' when running dotnet ef database update

EF Core's Migrate() always checks whether the database exists and creates it if not, from a hardcoded master connection. Grant CREATE ANY DATABASE, fix the login's access to the existing database, or ship an idempotent SQL script instead.

2026-08-30 errors ef-core maui

Fix: Model building is not supported when publishing with NativeAOT in a .NET MAUI iOS build

iOS builds set DynamicCodeSupport=false, so EF Core refuses to build the model even though you never enabled NativeAOT. Ship a compiled model plus precompiled queries, or turn the interpreter back on.

2026-08-29 errors dotnet csharp

Fix: CA1070 "Do not declare event fields as virtual"

CA1070 fires on virtual field-like events. Drop the virtual, keep the event non-virtual, and let derived classes override a protected virtual OnXxx raiser instead.
