Enumeration Type Documentation

CompilationRelaxations

enum System.Runtime.CompilerServices.CompilationRelaxations

strong

Specifies parameters that control the strictness of the code generated by the common language runtime's just-in-time (JIT) compiler.

Enumerator
NoStringInterning	Marks an assembly as not requiring string-literal interning.

Definition at line 9 of file CompilationRelaxations.cs.

LoadHint

enum System.Runtime.CompilerServices.LoadHint

strong

Specifies the preferred default binding for a dependent assembly.

Enumerator
Default	No preference specified.
Always	The dependency is always loaded.
Sometimes	The dependency is sometimes loaded.

Definition at line 5 of file LoadHint.cs.

MethodCodeType

enum System.Runtime.CompilerServices.MethodCodeType

strong

Defines how a method is implemented.

Enumerator
IL	Specifies that the method implementation is in Microsoft intermediate language (MSIL).
Native	Specifies that the method is implemented in native code.
OPTIL	Specifies that the method implementation is in optimized intermediate language (OPTIL).
Runtime	Specifies that the method implementation is provided by the runtime.

Definition at line 8 of file MethodCodeType.cs.

MethodImplOptions

enum System.Runtime.CompilerServices.MethodImplOptions

strong

Defines the details of how a method is implemented.

Enumerator
Unmanaged	The method is implemented in unmanaged code.
ForwardRef	The method is declared, but its implementation is provided elsewhere.
PreserveSig	The method signature is exported exactly as declared.
InternalCall	The call is internal, that is, it calls a method that is implemented within the common language runtime.
Synchronized	The method can be executed by only one thread at a time. Static methods lock on the type, whereas instance methods lock on the instance. Only one thread can execute in any of the instance functions, and only one thread can execute in any of a class's static functions.
NoInlining	The method cannot be inlined. Inlining is an optimization by which a method call is replaced with the method body.
AggressiveInlining	The method should be inlined if possible.
NoOptimization	The method is not optimized by the just-in-time (JIT) compiler or by native code generation (see Ngen.exe) when debugging possible code generation problems.
