Describe the bug

After upgrading my VS from 17.5.5 to 17.6.0 my Blazor application how has lot of errors. Most of them are : Cannot implicitly convert
type 'Microsoft.AspNetCore.Components.ElementReference' to MyComponent.
MyComponent inherits some other component.

This are relevant SO issues from today and yesterday, people have problem with something breaking going on:

• https://stackoverflow.com/questions/76286911/error-cs0029-cannot-implicitly-convert-type-microsoft-aspnetcore-components-el
• https://stackoverflow.com/questions/76274539/maui-blazor-cs0029-when-passing-component-ref

Expected Behavior

No response

Steps To Reproduce

Create .net7 blazor project
Create component which inherits from some other
Now, use this component somewhere <MyComponent @ref="myRef" /> and use @andrefboliveira

This used to work in 17.5.5

It is not problem for me to downgrade Visual Studio but on our CI/CD build inside docker fails since it pulls
dotnet build tooling from mcr.microsoft

Exceptions (if any)

No response

.NET Version

7.0.302

Anything else?
