Property Reference is invalid in LargeAddressAwareTargetAssembly

[CreateAndInject]

<PropertyGroup>
  <LargeAddressAwareTargetAssembly>bin/$(Configuration)/$(AssemblyName).exe</LargeAddressAwareTargetAssembly>
</PropertyGroup>

Are you sure it works?

In my test:
This is valid:
<LargeAddressAwareTargetAssembly>C:\repos\ConsoleApp1\ConsoleApp1\bin\Debug\net48\ConsoleApp1.exe</LargeAddressAwareTargetAssembly>

This is invalid, even if $(TargetPath) = C:\repos\ConsoleApp1\ConsoleApp1\bin\Debug\net48\ConsoleApp1.exe
<LargeAddressAwareTargetAssembly>$(TargetPath)</LargeAddressAwareTargetAssembly>

It doesn't support Property Reference at all, dont' know why do you give an incorrect description in README.md

Have you used https://msbuildlog.com to understand the order in which TargetPath is assigned?

@KirillOsenkov I tested, your way in README.md can only work with
<AppendTargetFrameworkToOutputPath>false</AppendTargetFrameworkToOutputPath>
Since the default output isn't bin/$(Configuration)/$(AssemblyName).exe at all

I have abandoned your way, and in final I use this code:

  <UsingTask TaskName="LargeAddressAwareTask" TaskFactory="CodeTaskFactory" AssemblyFile="$(MSBuildToolsPath)\Microsoft.Build.Tasks.Core.dll">
    <ParameterGroup>
      <TargetFile ParameterType="System.String" />
    </ParameterGroup>
    <Task>
      <Code>
        <![CDATA[
        using (var fs = new FileStream(TargetFile, FileMode.Open, FileAccess.ReadWrite))
        using (var br = new BinaryReader(fs))
        using (var bw = new BinaryWriter(fs))
        {
            fs.Position = 0x3C;
            fs.Position = br.ReadInt32() + 0x16;
            ushort characteristics = br.ReadUInt16();
            characteristics |= 0x20;
            fs.Position -= 2;
            bw.Write(characteristics);
        }
        ]]>
