Help upgrading Revit 2024 plugin (.NET Framework 4.8) to Revit 2025 (.NET 8)

Hello everyone,

I recently developed a Revit 2024 plugin using C# and Visual Studio, which currently runs on .NET Framework 4.8.
Now I’d like to use this same plugin in Revit 2025, but since Revit 2025 uses .NET 8, I’m not sure how to properly upgrade the project.

Could someone please explain:

How to reconfigure the project from .NET Framework 4.8 to .NET 8?
Whether I need to modify parts of the code, or if it’s mostly a change in the project configuration?

I would really appreciate any guidance.

Thanks in advance!

Hi @yonis_intini ,

One suggestion to upgrade your Revit project’s .NET Framework to .NET 8 is to use the Upgrade option. Please refer to the attached screenshot for guidance.

When you click Upgrade, the Microsoft.NET.UpgradeAssistant.vsix tool will be downloaded. Once installed, You can use this tool to upgrade your Revit projects seamlessly.

Additionally, I suggest reviewing the following Autodesk documentation for more details:https://help.autodesk.com/view/RVT/2025/ENU/?guid=Revit_API_Revit_API_Developers_Guide_Introduction_Getting_Started_Using_the_Autodesk_Revit_API_NET8_Update_html

you can also go into the project properties and change the .NET framework there right? thats what i did and it seemed to work okay.
