CsWinRT v0.1.0.201006.1

Release Notes

Refer to this list of breaking changes for .NET5 RC2.

Other known issues include:

• MarshalInterface.FromAbi doesn't handle the case where ptr is not the default interface. (#360)
• WinUI3 performance issues (#413)
• ReadyToRun is not supported for applications using the .NET5 Windows 10 TFM. These applications should install the latest .NET5 SDK from the RTM branch to get the fix. (#442)
• Projected XAML classes still require an explicit registration in the app startup path. This will be fixed in the RTM release. (#465)
