[ProfilerAPI] No more ModuleLoadFinished callbacks for dynamic modules #76016
Description
Hi there,
.NET 7.0 rc1 doesn't send ICorProfilerCallback::ModuleLoadFinished for dynamic modules any more. .NET 6.0.9 works properly.
Example:
using System;
using System.Reflection;
using System.Reflection.Emit;
namespace DynamicAssemblyTestProgram
{
internal static class DynamicAssemblyTestProgram
{
internal static void Main()
{
var type = AssemblyBuilder.DefineDynamicAssembly(new AssemblyName("TestAssembly"), AssemblyBuilderAccess.Run)
.DefineDynamicModule("TestModule")
.DefineType("TestClass", TypeAttributes.Public)
.CreateType();
var obj = Activator.CreateInstance(type);
if (obj == null)
throw new NullReferenceException();
Console.WriteLine("Done!");
Console.ReadKey();
GC.KeepAlive(obj);
}
}
}Profiler log, see 00007FFC14200110:
