Target Framework - Unable To Change

[Hugh_Compton]

Hello

When trying to follow the 'My First Plugin' tutorial using Revit 2020 and Visual Studio 2019 I am unable to change the 'Target Framework' to .net 4.7.

When I installed Visual Studio I used the Unity add-on which might be restricting which Frameworks I can use.....  

I have downloaded and installed .net Framework 4.7, 4.7.1, 4.7.2 and 4.8 but none of them show up in Visual Studio > Target Framework.

Probably there is some sort of error occurred in your visual studio installation. Because of Revit needs.Net Framework for run the add-ins. But you have only.Net Standard Library. I Suggest a new clean setup of Visual Studio. Here is a photo of how your visual studio should look. 

I hope this helps,

Recep.

Hi @Hugh_Compton ,

I think while creating the project you have chosen Class Library(.NET STANDARD) instead of Class Library(.NET FRAMEWORK).

As you see, Class Library(.NET FRAMEWORK) helps you to create .dll File which will help us to create Revit plugin.
