(CS0122) TabRenderer2019 Is inaccesiable because of it's Protection level.

[Aleida Duran]

I've been trying to use the 2019 tab style but every time I seem to get this error. I've taken a look inside the references of the DLL I've got but it also doesn't contain or show a reference of 2019 Tab Style. I tried the answer on another post which didn't seem to work and only more errors.

Hi Aleida,
