when you project is build for .NET Framework 4.8, it should load PresentationFramework 4.0,
not 3.0.
When you look at the project referneces in Visual Studio: what does it display for PresentationFramework?
PresentationFramework problem
I'm developing an app on VS2022 C# .NET4.5.2 WPF upgraded to .NET4.8
After the upgrade when running the .exe file on WIN11 I get the following error:
"Not possible to load th efile or assembly 'PresentationFramework', Version 3.0.0.0, Culture=neutral PublicKeyToken=31bf3856ad364e35 or one of its relative dependencies. Not possible to find the specified file"
How can I solve this problem?

Check references: Make sure your project references the correct version of the PresentationFramework assembly.
Check App.Config: If your application has an app.config file, remove any binding redirects related to PresentationFramework.
Check dependencies: If your project depends on any third-party libraries or packages, update all dependencies to the latest version that supports .NET Framework 4.8.
Check target framework: Double check that your project is correctly targeting .NET Framework 4.8. You can verify this by right-clicking the project in Visual Studio, selecting Properties, and navigating to the Application tab.
Check your environment: Make sure .NET Framework 4.8 is installed on your Windows 11 computer. If necessary, you can download and install it from the Microsoft website.
Rebuild Solution: After making any necessary changes, rebuild your solution to ensure that all changes are applied correctly.
