msftbot[bot] · web-flow · commit 5fe63f453c8f · 2021-01-07T18:23:43.000Z
## PR Type What kind of change does this PR introduce? - Refactoring (no functional changes, no api changes) ## What is the new behavior? This PR adds a set of forward compatibilty changes to ease the cross-compilation of the community toolkit to Uno Platform targets. - Partials are needed for code generation - Use `TargetFrameworks` instead of `TargetFramework` to allow for late modification of the platform list ## PR Checklist Please check if your PR fulfills the following requirements: - [ ] Tested code with current [supported SDKs](../readme.md#supported) - [ ] Pull Request has been submitted to the documentation repository [instructions](..\contributing.md#docs). Link:  - [ ] Sample in sample app has been added / updated (for bug fixes / features) - [ ] Icon has been created (if new sample) following the [Thumbnail Style Guide and templates](https://github.com/windows-toolkit/WindowsCommunityToolkit-design-assets) - [ ] New major technical changes in the toolkit have or will be added to the [Wiki](https://github.com/windows-toolkit/WindowsCommunityToolkit/wiki) e.g. build changes, source generators, testing infrastructure, sample creation changes, etc... - [ ] Tests for the changes have been added (for bug fixes / features) (if applicable) - [ ] Header has been added to all new source files (run *build/UpdateHeaders.bat*) - [x] Contains **NO** breaking changes  ## Other information
