Hi
I´m trying to create Base Forms / Pages for our C# net8 Application.
The Classes throw no Error and in net8 is everythin going well, but when i will start the Designer with framework4.8 then i get a exception.
The designer could not be displayed for this file because none of the classes it contains can be defined. The designer checked the following classes in the file: Page1 — The FrontendBasePage.Base`1 base class could not be loaded. Ensure that the assembly is referenced and all projects are built. BasePage — The base class System.Object cannot be designed.
Theres any way to go to create bases Pages / Forms and use them to other Pages / Forms?
Hello,
Please wrap up a sample following the guidelines under “Before Posting an Issue” https://wisej.com/support/question/forum-guidelines
We will see if we can reproduce with your sample and go from there.
Thanks,

Hi Frank,
yes thats the reason from this lines
<TargetFrameworks Condition=”‘$(Configuration)’ == ‘Design'”>net48;net8.0</TargetFrameworks>
<TargetFrameworks Condition=”‘$(Configuration)’ == ‘Debug'”>net8.0</TargetFrameworks>
so to start the designer we go to “Design” that the multi targeting is activ
With “normal” Pages and Forms that based on Page Or Forms is everything fine.
But wenn i create a BaseForm : Form and a Second MyForm : BaseForm.
I cant open the designer.
So the desinger throw the Error.
Or sometimes i get from “normal” Pages a “Timeout to connect with the named Pipe”
Hi Luca,
Wisej.NET designer needs .NET Framework 4.8 to work so you have to go with Multi Targeting.
Best regards
Frank
