1. Get latest updates from upstream (if you have not done so in last 3 weeks)
2. Then execute msbuild build.proj to update your build tools
3. Then regenerate your SDK using generate.cmd (this will regenerate couple of additional files)
4. build you project (ether IDE or command line)
5. Then update your PR
   With the latest changes, every regeneration will generate couple of additional meta data files that are needed in each PR.

@shahabhijeet I followed those steps already as you noted them in my initial PR: #3954

I did notice one extra file being generated when I built the project using the IDE, which I did not include here

[shahabhijeet]

@ro-joowan please include all those files, they are required.

@shahabhijeet Thank you pointing them out in detail! The process makes more sense now. I have updated this PR.
