New grasshopper reference breaking all my code - 4.8 .NET framework

[stephen_lewis]

Im having build errors just today after installing to latest rhino update. I believe it is because new grasshopper build is targeting the 4.8 framework and my version of VS is only offering .NET frame works up to 4.7.2. Any thoughts? How do i get the 4.8 .NET frame work from VS?

Can no longer rebuild original code after latest SR for Rhino

I cannot recompile an existing grasshopper project. Have no idea what is going on. It appears to be errors on the build side and no errors are showing up in the code. Never had this issue before. See below [image]

thanks, the messaging on the forum is acting weird for me. The option i did was to select “other frame works” in the build drop down and then that took me directly to a MS web page to download. Your suggestion is more thorough, thanks for replying.
