OutOfMemoryException (lots of large winforms designer files)

See original GitHub issue

Steps to reproduce

  1. I downloaded and installed latest version 8.4.6.0 from https://marketplace.visualstudio.com/
  2. I opened my VB.net project in VS2019 and right-clicked “Convert to C#”. The project has around 1200 VB forms including designer forms. Phase 1 was completed after 7 hours with having one error in one form.
  3. Phase 2 started, after around 40 forms I got the following error.
