Property Value Description
Option name dotnet_style_prefer_simplified_boolean_expressions

false Do not prefer simplified conditional expressions
Default option value true 
// dotnet_style_prefer_simplified_boolean_expressions = true
var result1 = M1() && M2();
var result2 = M1() || M2();

// dotnet_style_prefer_simplified_boolean_expressions = false
var result1 = M1() && M2() ? true : false;
var result2 = M1() ? true : M2();

Suppress a warning

If you want to suppress only a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.

#pragma warning disable IDE0075
// The code that's violating the rule is on this line.
#pragma warning restore IDE0075

To disable the rule for a file, folder, or project, set its severity to none in the configuration file.

[*.{cs,vb}]
dotnet_diagnostic.IDE0075.severity = none

To disable all of the code-style rules, set the severity for the category Style to none in the configuration file.

[*.{cs,vb}]
dotnet_analyzer_diagnostic.category-Style.severity = none
