Updated NSwag.AspNetCore from 14.7.0 to 14.7.1.

Release notes

Sourced from NSwag.AspNetCore's releases.

14.7.1

[!IMPORTANT]
Upgrade directly from v14.6.3 to v14.7.1 — skip v14.7.0.

v14.7.0 bundled NJsonSchema v11.6.0, which contained a regression that silently dropped nullability on required T? / [JsonRequired] T? DTO properties. The resulting OpenAPI/JSON schema marked those properties as non-nullable, so generated TypeScript and C# clients lost null-safety for fields the server can legitimately return as null (#​5359).

Corrections to v14.7.0

v14.7.1 updates to NJsonSchema v11.6.1, which corrects the handling of the C# required keyword and [JsonRequired]:

  • These are now treated as presence markers (the property must be present in the JSON) rather than value constraints.
  • Nullability from the declared type (string?, T?) is preserved.
  • No spurious MinLength=1 on non-nullable strings.
  • DataAnnotations [Required] semantics remain unchanged (still suppresses nullability and adds MinLength=1 to strings by default, matching its runtime behavior).

Observable client changes vs v14.7.0

For public required string[]? OptionList { get; init; } (#​5359):

TypeScript client C# client
v14.7.0 (broken) optionList: string[] public string[] OptionList
v14.7.1 optionList: string[] | null public string[]? OptionList

For full details and truth tables across all required / [Required] / [JsonRequired] / [JsonProperty(Required=*)] combinations, see the NJsonSchema v11.6.1 release notes and NJsonSchema #​1919.

Looks like NSwag.AspNetCore is no longer updatable, so this is no longer needed.
