Bump NJsonSchema from 11.3.2 to 11.6.1

[dependabot]

Updated NJsonSchema from 11.3.2 to 11.6.1.

Release notes

Sourced from NJsonSchema's releases.

11.6.1

[!IMPORTANT]
v11.6.0 should not be used — it introduced a regression that caused required T? / [JsonRequired] T? properties to incorrectly lose their nullability and gain a spurious MinLength=1 on strings. Please upgrade directly from v11.5.x to v11.6.1.

Corrections to v11.6.0

v11.6.0 added support for the C# 11 required keyword and [JsonRequired] in schema generation (#​1908), but folded them into the same bucket as DataAnnotations [Required] — which conflated three distinct concepts:

• Presence (belongs in schema's required array): required keyword, [JsonRequired], [Required], [DataMember(IsRequired=true)], Newtonsoft Required.Always/AllowNull
• Non-null value (suppresses nullable): [Required] only (plus Newtonsoft Required.Always/DisallowNull for runtime correctness)
• Non-empty string (MinLength=1 on strings): [Required] only (unless AllowEmptyStrings=true)

v11.6.1 (#​1919) restores the correct separation. The required keyword and [JsonRequired] are now presence-only markers — they add the property to the schema's required array without suppressing nullability or adding MinLength=1.

Behavioral deltas vs v11.6.0 (all restoring correctness)

C# declaration	v11.6.0 (broken)	v11.6.1
required string?	nullable: false, MinLength: 1 ❌	nullable: true, no MinLength ✅
required string	MinLength: 1 ❌	no MinLength ✅
[JsonRequired] string?	nullable: false, MinLength: 1 ❌	nullable: true, no MinLength ✅
[JsonRequired] string	MinLength: 1 ❌	no MinLength ✅

[Required], [JsonProperty(Required=*)], and [DataMember(IsRequired=true)] semantics are unchanged across v11.5.x / v11.6.0 / v11.6.1.

Downstream impact

The v11.6.0 regression surfaced in NSwag as NSwag#​5359: TypeScript clients generated from required T? DTO properties silently lost their | null, removing null-safety for fields the server can legitimately return as null. v11.6.1 fixes this. A matching NSwag release is required to pick up the fix.

11.6.0

[!CAUTION]
Do not use this release — upgrade to v11.6.1 or later.

v11.6.0 introduced a regression in the handling of the C# required keyword and [JsonRequired]: required T? / [JsonRequired] T? properties incorrectly lost their nullability and gained a spurious MinLength=1 on strings. This broke downstream client generation — see NSwag#​5359. Fixed in v11.6.1 (#​1919).

Potentially breaking changes

• C# 11 required keyword now recognized as required: Properties using the C# 11 required keyword (RequiredMemberAttribute / JsonRequiredAttribute) are now correctly treated as required in schema generation and code output. Previously these were incorrectly treated as optional (Required.Default). This changes generated code: such properties now get Required.Always, [Required] attribute, and the required modifier when UseRequiredKeyword is enabled. (#​1908)
• Both JsonStringEnumMemberName and EnumMember attributes are now emitted for enum members when using System.Text.Json, for compatibility with NSwag's reflection-based URL parameter serialization. (#​1905)
• $schema version preserved in ToJson() instead of forcing draft-04. If you relied on the output always being draft-04, this may affect you. (#​1881)
• patternProperties validation now correctly applies to all matching properties, not just the first. (#​1898)
• MinLength no longer incorrectly applied to DateTime, DateTimeOffset, DateOnly, TimeOnly properties. (#​1900)
