How to compile using 2.2.6?

Hi,

I have my ASP.NET Web API project and in the project properties I selected target Framework as .NET Core 2.2 (because that's the latest listed in my Visual Studio 2019)

but I am having a problem with the project when I upload to my host so they asked me to recompile using 2.2.6

How can I do that please?

Thanks,

Jassim
