[Question] SetProperty not overloaded property in .NET 6 ? about dotnet

It seems like you're invoking with SetProperty with incorrect arguments, VS is correct here.
The signature you showed takes both T parameters by value, but you're passing the first one by ref, which is incorrect.
You should change your call to:

SetProperty(selectedRole, value, t => { });

Which will bind to the method you mentioned 😊

As a side, I would not recommend using that specific overload unless absolutely necessary.
Use the one taking a backing field if available, or use the one also taking a target model if you're proxying a property.
It will remove allocations and result in better performance.

Closing this as the code you showed doesn't seem to be an actual issue in the MVVM Toolkit.
