Configuration Details

Setting Value
Ignored Extensions .cache, .DS_Store, .db, .ilcache, .log, .pdb
Text File Extensions .asax, .ascx, .asmx, .aspx, .bat, .c, .cmd, .config, .cpp, .cs, .cshtml, .csproj, .csx, .css, .csv, .editorconfig, .env, .fs, .fsi, .fsproj, .fsx, .gitattributes, .gitignore, .gitmodules, .go, .gql, .graphql, .h, .hpp, .htm, .html, .http, .ini, .js, .json, .jsx, .less, .manifest, .md, .mod, .nlog, .nuspec, .plist, .props, .ps1, .psd1, .psm1, .py, .razor, .resx, .rst, .sass, .scss, .sh, .sln, .sql, .sqlproj, .sum, .svg, .targets, .toml, .ts, .tsv, .tsx, .txt, .vb, .vbproj, .vue, .xaml, .xml, .yaml, .yml

IL Ignored Strings — When diffing IL, lines containing any of the configured strings are ignored:

Ignored String
"buildserver1_"
"buildserver2_"
"// Method begins at Relative Virtual Address (RVA) 0x"
".publickeytoken = ( "
".custom instance void class [System.Windows.Forms]System.Windows.Forms.AxHost/TypeLibraryTimeStampAttribute::.ctor(string) = ( "
"// Code size "
"rva"

Note: When diffing IL, lines starting with "// MVID:" (if present) are ignored because they contain disassembler-emitted Module Version ID metadata that can change on rebuild without meaning the executable IL changed.
