Pull request overview
This PR fixes issue #4597 by correctly converting nullable types when using MapAtRuntime(). The issue occurred when mapping from a non-nullable value type (e.g., int from an extension method result) to a nullable destination property (e.g., int?) with MapAtRuntime enabled.
Changes:
- Added type conversion in
ContextMapto ensure source expressions match the expected generic type parameter - Added comprehensive test coverage for the nullable conversion scenario with extension methods

Signed packages means going forward packages can be validated against trusted authorities that the package has been published by Lucky Penny Software and not tampered with. ## 15.1.0 ## What's Changed * remove Microsoft.SourceLink.GitHub by @SimonCropp in LuckyPennySoftware/AutoMapper#4555 * Direct .NET 4.x support by @jbogard in LuckyPennySoftware/AutoMapper#4569 * Bumping the JsonWebTokens because of GHSA-8g4q-xg66-9fp4; fixes #4575 by @jbogard in LuckyPennySoftware/AutoMapper#4576 * Provide better exceptions for errors when building the mapping plan by @jbogard in LuckyPennySoftware/AutoMapper#4577 * Adding docs for license configuration by @jbogard in LuckyPennySoftware/AutoMapper#4581 * Updating refs to fix missing method issue by @jbogard in LuckyPennySoftware/AutoMapper#4582 ## New Contributors * @SimonCropp made their first contribution in LuckyPennySoftware/AutoMapper#4555 **Full Changelog**: LuckyPennySoftware/AutoMapper@v15.0.1...v15.1.0 ## 15.0.1 ## What's Changed * Removing public signing; fixes #4545 by @jbogard in LuckyPennySoftware/AutoMapper#4552 * Adding back missing overloads and reverting registering behavior by @jbogard in LuckyPennySoftware/AutoMapper#4554 **Full Changelog**: LuckyPennySoftware/AutoMapper@v15.0.0...v15.0.1 This release supersedes the 15.0.0 release, reverting behavior and overloads so that the `AddAutoMapper` overloads separate the "scanning for maps" from the "scanning for dependencies". Unfortunately it's not really possible to combine these two together. This also fixes a critical bug in #4545 that does not work with .NET 4.x applications (as intended). Because of this, the 15.0.0 will be delisted because of the breaking changes there. ## 15.0.0 **Full Changelog**: LuckyPennySoftware/AutoMapper@v14.0.0...v15.0.0 * Added support for .NET Standard 2.0 * Requiring license key * Moving from MIT license to dual commercial/OSS license To set your license key: ```csharp services.AddAutoMapper(cfg => { cfg.LicenseKey = "<License key here>"; }); ``` This also introduced a breaking change with `MapperConfiguration` requiring an `ILoggerFactory` for logging purposes: ```csharp public MapperConfiguration(MapperConfigurationExpression configurationExpression, ILoggerFactory loggerFactory) ``` Registering AutoMapper with `services.AddAutoMapper` will automatically supply this parameter. Otherwise you'll need to supply the logger factory.
