v1.7.0

Added

• Add IDE0033 — explicit tuple names rule (dotnet_style_explicit_tuple_names), flags tuple.Item1 when named elements are available

• Add IDE0062 — prefer static local function rule (csharp_prefer_static_local_function), flags non-static local functions that don't capture enclosing state

v1.6.0

Added

• Add 8 expression/style rules: CSLINT270–276, IDE0200 (pattern matching over as, conditional delegate call, inlined variable declaration, switch expression, conditional expression over assignment/return, local over anonymous function, method group conversion)
• Add 2 using-directive rules: CSLINT277–278 (sort System first, separate import groups)
• Add 7 new-line formatting rules: CSLINT279–285 (brace placement, else/catch/finally, initializers, anonymous types, query clauses)
• Add 6 spacing rules: CSLINT286–291 (cast, method parens, dot, square bracket, declaration spacing)
• Add 2 formatting rules: CSLINT292 (indentation), CSLINT293 (preserve single-line)
• Add IDE0210 (top-level statements), IDE0130 (namespace match folder)
• Add IDE1006 — standard 3-part naming convention system (dotnet_naming_rule, dotnet_naming_symbols, dotnet_naming_style)
• Accept standard .editorconfig keys as aliases for existing rules: _experimental suffix keys for blank line rules (CSLINT008, CSLINT228–233), charset for CSLINT010, null-checking keys for CSLINT210, and standard spacing keys for CSLINT254–261

Changed

• Disable CSLINT100–106 hardcoded naming rules when standard 3-part naming config is present (IDE1006 takes over)
• New rules with 1:1 standard mappings now use the standard IDE diagnostic ID directly (e.g., IDE0200) instead of CSLINT* IDs
• Use ASCII hyphens instead of Unicode box-drawing characters in --summary table separators

Fixed

• Fix IDE0019 pragma alias (was incorrectly mapped to CSLINT209, now CSLINT270)
• Fix IDE0066 pragma alias (was incorrectly mapped to CSLINT209, now CSLINT273)

v1.5.0

Added

• Add --rules CLI option to run specific rules ignoring .editorconfig (e.g., --rules CSLINT266,CSLINT268 or --rules all)
• Add --summary CLI option to show diagnostics grouped by rule ID

v1.4.1

Fixed

• Fix CSLINT238 false positives on const fields (constants require an initializer, so const int X = 0 is not unnecessary)
• Fix CSLINT251 false positives on struct fields (public fields are common and accepted in structs)

v1.4.0

Added

• Accept multiple path arguments on the command line (e.g., cslint src/ProjectA src/ProjectB)

v1.3.1

Fixed

• Fix CSLINT106 false positives on type parameters with digit suffixes (e.g., T0, T1, T2)

v1.3.0

Added

• Add CSLINT263 — accessor ordering: get before set/init in properties, add before remove in events (SA1212, SA1213)
• Add CSLINT264 — readonly fields must appear before mutable fields (SA1214)

• Add CSLINT267 — element access modifier ordering: public → internal → protected → private (SA1202)
• Add CSLINT268 — element kind ordering: fields → constructors → properties → methods → nested types (SA1201)
• Add CSLINT269 — using directive ordering: System first, alphabetical, regular → static → alias (SA1208, SA1209, SA1210, SA1211, SA1216, SA1217)
• Add CSLINT010 — store files as UTF-8 encoding check (SA1412), with pragma alias SA1412
• Add 7 StyleCop readability rules: CSLINT240 (no empty statements), CSLINT241 (single statement per line), CSLINT242 (no Yoda conditions), CSLINT243 (no combined field declarations), CSLINT244 (no combined attributes), CSLINT245 (attributes on own line), CSLINT246 (enum values on separate lines)

• Add 3 StyleCop maintainability rules: CSLINT251 (fields must be private), CSLINT252 (single type per file), CSLINT253 (trailing commas in multi-line initializers)
• Add CSLINT106 — type parameter names must begin with T (SA1314)
• Add 9 StyleCop spacing rules: CSLINT254 (keyword spacing), CSLINT255 (comma spacing), CSLINT256 (semicolon spacing), CSLINT257 (operator spacing), CSLINT258 (comment spacing), CSLINT259 (parenthesis spacing), CSLINT260 (brace spacing), CSLINT261 (colon spacing), CSLINT262 (no multiple whitespace)
• Add 13 StyleCop pragma aliases for already-covered rules (SA1027, SA1028, SA1101, SA1121, SA1124, SA1206, SA1303, SA1312, SA1400, SA1500, SA1503, SA1507, SA1518)
• Add 22 pragma aliases for new StyleCop rules (SA1000–SA1136, SA1401–SA1517)
• Add 12 pragma aliases for ordering rules (SA1201–SA1204, SA1208–SA1211, SA1214, SA1216, SA1217)
• Add CSLINT308 — unused private member detection (fields, methods, properties, events) with pragma aliases IDE0051, IDE0052, CS0169, CS0414

Changed

• Enhance CSLINT104 (FieldNamingRule) to check non-private readonly and static readonly fields for PascalCase (SA1304, SA1307, SA1311)

v1.2.1

Added

• Add --version CLI option

Fixed

• Fix CSLINT230 false positive when preprocessor directives appear between a block and the next statement
• Fix test project build when semantic rules are excluded

v1.2.0

Added

• Add opt-in semantic analysis mode (--semantic) with shared compilation
• Add CSLINT239 — prefer sealed types (CA1852)
• Add CSLINT301 — unused local variable rule
• Add CSLINT302 — unreachable code rule

• Suppress CSLINT300 when references are missing

v1.1.1

What's Changed

Bug Fixes

• CSLINT237 / CSLINT238: Use GetValueWithSeverity for config parsing in EmptyFinalizerRule and UnnecessaryInitializationRule, consistent with other Tier 3 rules. Previously these rules used GetValue which ignored the severity suffix in .editorconfig values (e.g. true:warning).
