Ahead of the time compilation to machine code

• produces self-contained application which:
  • starts quicker
  • uses less memory
  • does not require .NET runtime installed
• it is better for workloads with high deployment instances (clouds)
• makes runtime code generation impossible
• not all libraries are compatible

Just – in – time compiler.

• part of CLR
• for all .net programs for all .net languages
• converts MSIL to native machine code
• compiles code when it is necessary at runtime
• also it is possible to pre-compile to native code at compile time instead

• can be class or struct
• creates methods overrides for enforcing value equality instead of reference equality:
  • Object.Equals
  • Object.GetHashCode
  • operators
    • ==
    • !=
• implements IEquatable<> parameter
• implements ToString
• supports deconstruction
• supports with expression
• meant to be immutable

Positional records is a more concise syntax for record:

• primary constructor parameters match the positional parameters of the record declaration
• public init-only properties for each parameter

We can.

• for some critical part of application code using GC.TryStartNoGCRegion method.
• using CER (Constrained Execution Regions) (obsolete)
• with GC LatencyModes
