Code Issues - Invalid code analysis warning when analyzing potential null reference in the "is { } pattern" expression

created 6 months ago

Using the below code, it's telling me that declaringType isn't checked for null on the last line show. The previous line though is going to guarantee that declaringType isn't null, to the best of my understanding.

C#
public sealed class SwaggerAuthenticationRequirementsOperationFilter : IOperationFilter { public void Apply(OpenApiOperation operation, OperationFilterContext context) { if (context.MethodInfo.DeclaringType is { } declaringType) { var declaringTypeAttributes = declaringType.GetCustomAttributes(inherit: true);
