When this attribute is applied to a class, interface, or struct, the members specified can be accessed dynamically on instances returned from calling on instances of that class, interface, or struct. If the attribute is applied to a method it's treated as a special case and it implies the attribute should be applied to the "this" parameter of the method. As such the attribute should only be used on instance methods of types assignable to System.Type (or string, but no methods will use it there).

The property is an optional argument that specifies additional exclusion where the literal metadata target is not sufficiently precise.

Disables the built-in runtime managed/unmanaged marshalling subsystem for P/Invokes, Delegate types, and unmanaged function pointer invocations.

The built-in marshalling subsystem has some behaviors that cannot be changed due to backward-compatibility requirements. This attribute allows disabling the built-in subsystem and instead uses the following rules for P/Invokes, Delegates, and unmanaged function pointer invocations: - All value types that do not contain reference type fields recursively (unmanaged in C#) are blittable - Value types that recursively have any fields that have [StructLayout(LayoutKind.Auto)] are disallowed from interop. - All reference types are disallowed from usage in interop scenarios. - SetLastError support in P/Invokes is disabled. - varargs support is disabled. - LCIDConversionAttribute support is disabled.

Reserved to be used by the compiler for tracking metadata. This class should not be used by developers in source code.

Used to indicate to the compiler that a method should be called in its containing module's initializer.

When one or more valid methods with this attribute are found in a compilation, the compiler will emit a module initializer which calls each of the attributed methods. Certain requirements are imposed on any method targeted with this attribute: - The method must be `static`. - The method must be an ordinary member method, as opposed to a property accessor, constructor, local function, etc. - The method must be parameterless. - The method must return `void`. - The method must not be generic or be contained in a generic type. - The method's effective accessibility must be `internal` or `public`. The specification for module initializers in the .NET runtime can be found here: https://github.com/dotnet/runtime/blob/main/docs/design/specs/Ecma-335-Augments.md#module-initializer

Specifies that a type has required members or that a member is required.

Used to indicate to the compiler that the .locals init flag should not be set in method headers.

An attribute used to indicate a GC transition should be skipped when making an unmanaged function call.

Example of a valid use case. The Win32 `GetTickCount()` function is a small performance related function that reads some global memory and returns the value. In this case, the GC transition overhead is significantly more than the memory read.


             using System;
             using System.Runtime.InteropServices;
             class Program
             {
                 [DllImport("Kernel32")]
                 [SuppressGCTransition]
                 static extern int GetTickCount();
                 static void Main()
                 {
                     Console.WriteLine($"{GetTickCount()}");
                 }
             }

This attribute is ignored if applied to a method without the . Forgoing this transition can yield benefits when the cost of the transition is more than the execution time of the unmanaged function. However, avoiding this transition removes some of the guarantees the runtime provides through a normal P/Invoke. When exiting the managed runtime to enter an unmanaged function the GC must transition from Cooperative mode into Preemptive mode. Full details on these modes can be found at https://github.com/dotnet/runtime/blob/main/docs/coding-guidelines/clr-code-guide.md#2.1.8. Suppressing the GC transition is an advanced scenario and should not be done without fully understanding potential consequences. One of these consequences is an impact to Mixed-mode debugging (https://docs.microsoft.com/visualstudio/debugger/how-to-debug-in-mixed-mode). During Mixed-mode debugging, it is not possible to step into or set breakpoints in a P/Invoke that has been marked with this attribute. A workaround is to switch to native debugging and set a breakpoint in the native function. In general, usage of this attribute is not recommended if debugging the P/Invoke is important, for example stepping through the native code or diagnosing an exception thrown from the native code. The runtime may load the native library for method marked with this attribute in advance before the method is called for the first time. Usage of this attribute is not recommended for platform neutral libraries with conditional platform specific code. The P/Invoke method that this attribute is applied to must have all of the following properties: * Native function always executes for a trivial amount of time (less than 1 microsecond). * Native function does not perform a blocking syscall (e.g. any type of I/O). * Native function does not call back into the runtime (e.g. Reverse P/Invoke). * Native function does not throw exceptions. * Native function does not manipulate locks or other concurrency primitives. Consequences of invalid uses of this attribute: * GC starvation. * Immediate runtime termination. * Data corruption.

Any method marked with can be directly called from native code. The function token can be loaded to a local variable using the address-of operator in C# and passed as a callback to a native method.

Methods marked with this attribute have the following restrictions: * Method must be marked "static". * Must not be called from managed code. * Must only have blittable arguments.

Optional. If omitted, the runtime will use the default platform calling convention.

Supplied types must be from the official "System.Runtime.CompilerServices" namespace and be of the form "CallConvXXX".

Optional. If omitted, no named export is emitted during compilation.

In conjunction with the or methods, this method may be used to implement the Begin/End pattern (also known as the Asynchronous Programming Model pattern, or APM). It is recommended to not expose this pattern in new code; the methods on are intended only to help implement such Begin/End methods when they must be exposed, for example because a base class provides virtual methods for the pattern, or when they've already been exposed and must remain for compatibility. These methods enable implementing all of the core asynchronous logic via s and then easily implementing Begin/End methods around that functionality.
