CommunityToolkit.Maui
CommunityToolkit.Maui.Core
CommunityToolkit.Maui.Embedding
CommunityToolkit.Maui.UnitTests
CommunityToolkit.Maui.Markup
CommunityToolkit.Maui.Markup.UnitTests

Original prompt

I want to remove the InternalsVisibleTo attribute for all the .NET MAUI Community Toolkit references. We reverted those changes once here: #29321

Ignore all the other changes, only add back the removal of the InternalsVisibleTo. Target the main branch.

…Toolkit (#33442)" This reverts commit 8e96657.

#34047) ### Description of Change This reverts commit 8e96657. (from #33442) Context : #29321 > Revert for now because the timing doesn't line up yet. We don't have a version of the Toolkit that uses the public types so with this change, the .NET 10 preview templates (using --sample-content) using the Toolkit will break immediately. This is still not true as per the time we're discussing this, so there's no good reason to introduce those changes (from #33442) in a service release, as this is a massive breaking change. Making the version unusable for everyone using the toolkit. Not to mention that 10.0.40 has some important bug fixes related to different crashes, which makes this situation quite annoying ### Issues Fixed Fixes #34035 Fixes #34034 Fixes #34048 #### Toolkit issues related [https://github.com/CommunityToolkit/Maui/issues/3089](https://github.com/CommunityToolkit/Maui/issues/3089) [https://github.com/CommunityToolkit/Maui/issues/3092](https://github.com/CommunityToolkit/Maui/issues/3092)
