Cannot browse into RevitAPI.dll or any others using VisualStudio

Hi I've encountered this error message: "The selected component could not be browsed" when trying to look into the Revit API namespaces in Visual Studio 2019. I'm new to both, but I believe I did the right thing to open Object Browser, direct to Custom Component Set and direct to RevitAPI.dll

Right mouse click on references in solution explorer, and click 'add reference', then 'Browse' and add both RevitAPI.dll and RevitAPIUI.dll

Thanks for the reply Joshua. I found out it was because that I didn't install the .Net core. Browse the .dll into Object Browser is just fine upon installation,

Maybe Visual Studio does not support browsing into a DLL that you have not created yourself.

You are not the owner of the code, after all.

I suggest that you make do with the official Revit API documentation provided in the Revit API help file RevitAPI.chm included with the Revit SDK, and available online for older versions here:

https://www.revitapidocs.com/

That lists all the Revit API classes with their methods and properties.

You can also use RevitLookup to browse live instances of these object in the Revit BIM:

Thanks Jeremy, I'll sure check them out.

Hi, same problem. What do you mean by install .NET core ? I installed .NET 6.03 and still does not work for me

Had same problem, found solution- when you install VS you have to install these two packages:

.NET desktop development 

Universal Windows Platform development
