This directory contains source files used to build Accessibility.dll, the managed wrapper for COM accessibility interface.

See https://docs.microsoft.com/en-us/dotnet/api/accessibility

Source in this directory is generated by a tool and should not be modified directly.

To produce the IL source the following process is used:

1. Use https://aka.ms/tlbimp to generate an assembly for oleacc.dll

tlbimp c:\windows\system32\oleacc.dll /out:Accessibility.dll

2. Use ildasm to disassemble that assembly.

ildasm Accessibility.dll /out=Accessibility.il

3. Replace the desktop assembly references with their corresponding .NETCore assemblies (since .NETCore doesn't provide a version of tlbimp.exe yet)

   • replace [mscorlib]System.Runtime.InteropServices with [INTEROP_ASSEMBLY]System.Runtime.InteropServices
   • replace [mscorlib] with [CORE_ASSEMBLY]
   • review the diff

4. Add assembly level attributes to the IL
