I am unable to program any SC20100S. I was able to program it earlier today. Instead of deploying it just starts the debugger and runs the code that is already present. I already tried to reinstall the TinyCLR addon, update Visual Studio and I erased the SC20100S.
Thanks for the quick reply! Sadly none of the options seemed to fix my problem, but I figured it out. I have a library project in my solution where a reference was wrongly defined. When I removed this reference it deploys the code like normal again.
