Issue with fluentvalidation where it is not populated in dot net 6

[jeremiedevos]

I have created RCL where I store all my components, because I'm not sure if I will switch to dot net Maui in a later stage of development. I have added the fluentvalidation nuget package to the RCL with the same version and have referenced the client to the RCL. However, when I create a new Editform with the validation (as is done in for example Profile.razor.cs), but it is telling me it is declared is null. This is not the case with the default implemented components from the template.

When does it occur:

• When moving component from Client to RCL (with updating namespaces)
• When making a new component in the RCL

The component code comparison

As you can see in the top (Moved Component) there is missing a reference, but everything is the same in the code.

Error in the browser

Folder hierarchy

Am I missing any configuration?
Any idea how I can fix this?
