Introduced in 0.24.0
Use of mutation to initialize properties with values.
There's no need to use mutation to initialize properties with values because F# has specific syntax for this kind of intitialization.
Both approaches will compile to the same IL but non-mutable code doesn't look unsafe because it prevents the use of the <- operator.
Replace all occurrences of mutable property initialization with non mutable property initialization.
Example: Cookie(Domain = "example.com") instead of let c = Cookie(); c.Domain <- "example.com"
{
"FavourNonMutablePropertyInitialization": { "enabled": false }
}
