[Blazor] LayoutAttribute.LayoutType should have proper trimming annotation

[yugabe]

The LayoutAttribute property in Microsoft.AspNetCore.Components.LayoutAttribute should also have [DynamicallyAccessedMembers(Component)] annotation. Currently, only the constructor parameter is annotated, which gives consumers of the attribute a false warning when accessing the property.

aspnetcore/src/Components/Components/src/LayoutAttribute.cs

Line 39 in d434929

public Type LayoutType { get; private set; }

Should be:

[DynamicallyAccessedMembers(Component)]
public Type LayoutType { get; private set; }
