Definition

Loads an assembly into the reflection-only context, where it can be examined but not executed.

Overloads

ReflectionOnlyLoad(Byte[])
Obsolete.

Loads the assembly from a common object file format (COFF)-based image containing an emitted assembly. The assembly is loaded into the reflection-only context of the caller's application domain.

ReflectionOnlyLoad(String)
Obsolete.

Loads an assembly into the reflection-only context, given its display name.

Caution

ReflectionOnly loading is not supported and throws PlatformNotSupportedException.

Loads the assembly from a common object file format (COFF)-based image containing an emitted assembly. The assembly is loaded into the reflection-only context of the caller's application domain.

public static System.Reflection.Assembly ReflectionOnlyLoad (byte[] rawAssembly);
[System.Obsolete("ReflectionOnly loading is not supported and throws PlatformNotSupportedException.", DiagnosticId="SYSLIB0018", UrlFormat="https://aka.ms/dotnet-warnings/{0}")]
public static System.Reflection.Assembly ReflectionOnlyLoad (byte[] rawAssembly);

Parameters

rawAssembly
Byte[]

A byte array that is a COFF-based image containing an emitted assembly.

Returns

The loaded assembly.

Attributes

Exceptions

rawAssembly is null.

rawAssembly is not a valid assembly for the currently loaded runtime.

rawAssembly cannot be loaded.

.NET Core and .NET 5+ only: In all cases.

Remarks

You cannot execute code from an assembly loaded into the reflection-only context. To execute code, the assembly must be loaded into the execution context as well, using the Load method.

The reflection-only context is no different from other contexts. Assemblies that are loaded into the context can be unloaded only by unloading the application domain.
