?? and ??= operators - null-coalescing operators - C# reference
The null-coalescing assignment operator ??= assigns the value of its right-hand operand to its left-hand operand only if the left-hand operand evaluates to null. The ??= operator doesn't evaluate its right-hand operand if the left-hand operand evaluates to non-null.
Assignment operators - assign an expression to a variable ...
You can use thenull-coalescing assignment operator ??= to assign the value of its right-hand operand to its left-hand operand only if the left-hand operand evaluates to null. For more information, see the ?? and ??= operators article.

In the same C# 8.0 release, the null-coalescing assignment operator (??=) has been introduced (see the docs). I understand the behavior, but which problem(s) does it solve for us? Why would we want to assign b to x when it's null x ??= b and have e.g. x = a when it's not null?
C# 8 - Null coalescing/compound assignment
There are a lot of cool new features in C# 8 and one of my favorites is the new Null coalescing assignment (or compoundassignment, whichever you prefer) operator. _someValue = InitializeMyValue(); } return _someValue; } private string InitializeMyValue() { // Do some expensive initialization that we only want to do once...
Coalescing operator and Compound assignment operator in C#
First, anull coalescing operator (??) is used to define a default value for nullable value types or reference types. It returns the left-hand operand if the operand is not null, otherwise, it returns the right operand.
Null-Coalescing Assignment Operator in C# 8.0 - GeeksforGeeks
C# 8.0 has introduced a new operator that is known as a Null-coalescing assignment operator (??=). This operator is used to assign the value of its right-hand operand to its left-hand operand, only if the value of the left-hand operand is null.
Null-Coalescing Assignment Operator In C# 8.0 - C# Corner
C# 8.0 introduces the null-coalescing assignment operator ??=. You can use the ??= operator to assign the value of its right-hand operand to its left-hand operand only if the left-hand operand evaluates to null.
Null Operators and Handling Null Values in C# - Medium
C# provides three operators to make it easier to work with nulls: the null-coalescing operator, the null-coalescing assignment operator, and the null-conditional operator.

According to ms docs, the null-coalescingoperator ?? returns the value of its left-hand if it isn't null; otherwise, it evaluates the right-hand operand and returns its result. The ?? operator does not evaluate its right-hand operand if the left-hand operand evaluates to non-null.

Useexp += val instead of exp = exp + val. Since exp can be arbitrarily complex, this can result in lots of unnecessary work. This forces the JIT to evaluate both copies of exp, and many times this is not needed.

The null-coalescing assignment operator ??= assigns the value of its right-hand operand to its left-hand operand only if the left-hand operand evaluates to null. The ??= operator doesn't evaluate its right-hand operand if the left-hand operand evaluates to non-null.
