Preventing SQL injection in C# with Entity Framework

SQL injection (SQLi) is a severe security threat that happens when malicious SQL code is injected into user inputs, potentially compromising the database. To avoid SQLi, it's crucial to avoid using string concatenation for SQL queries. Instead, Entity Framework (EF) offers secure options: LINQ for most queries, FromSqlInterpolated for raw SQL using string interpolation, and FromSqlRaw when explicit parameters are defined. Tools like Snyk Code can help detect unsafe code during development.
