Core 1.4.0

v1.4.0 - 30 June 2026

• Add: WithExecutePrivilege<T>(Privilege) on the Custom API builder for type-safe execute-privilege configuration, e.g. .WithExecutePrivilege<Account>(Privilege.Read) resolves to prvReadaccount. A WithExecutePrivilege(string entityLogicalName, Privilege) overload is available for late-bound scenarios. The existing WithExecutePrivilegeName(string) remains for non-standard privilege names.
• Add: Type-safe Custom API request/response wrappers. RegisterAPI<TService>(name, handlerMethodName) now generates {ApiName}Request/{ApiName}Response classes (named after the API, in the plugin's namespace) from the AddRequestParameter/AddResponseProperty declarations. The handler accepts the request and returns the response; a generated ActionWrapper marshals InputParameters into the request and the returned response into OutputParameters. When no request parameters are declared the handler takes no argument, and when no response properties are declared it returns void.
• Add: Error XPC4004: Custom API handler method not found (with code fix to create the method).
• Add: Warning XPC4005 / Error XPC4006: Custom API handler signature does not match the declared request parameters and response properties (with code fix to correct the signature).
• Add: XPC3001 (Prefer nameof over string literal) now also covers the Custom API handler argument.
• Add: Warning XPC3006: the typed RegisterAPI<TService>(name, handlerMethodName) overload requires a compile-time constant name (so the generated classes can be named after the API); a non-constant name is reported instead of silently skipping generation.
• Add: The typed RegisterAPI<TService>(name, handlerMethodName) overload now throws ArgumentException when the name or handler method name is null or whitespace, so misconfigurations fail fast at registration instead of being silently treated as "no registration" at execution time.
• Fix: Generated image properties now mirror the [Obsolete] attribute of the underlying entity property, so deprecation warnings (CS0612/CS0618) surface in the calling code instead of inside the auto-generated image class.
• Fix: Generated code (images and Custom API request/response) now only emits nullable reference-type annotations (string?) and a #nullable enable directive when the consuming project has nullable reference types enabled. On projects without NRT (including .NET Framework / C# 7.3 defaults) the generated code is emitted without those annotations, keeping it compilable and warning-free. Nullable value types (int?) are always emitted.
