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

Ok, issue is, VS doesn’t offer currently a 4.8 target by default need to install the developer pack for 4.8 outside of VS, once installed, 4.8 target is available and all projects need to be recompiled against 4.8.

My build works now. success.

Apologies for multiple threads, this is due to not targeting to 4.8 frame work and default install of VS not allowing for a 4.8 target. Issue is resolved in other threads.
