.NET Core can´t connect to SQL DB

Question

I build a new .net Core Web API with connection to SQL DB. I have problems to connect the API with my Database I tried a local DB \"DefaultConnection\": \"Server=(loca

Answer 1

The Problem in this case was the instance Server=192.168.1.XXX\\SQL2012;. I don't know why but the system can't handle it. I use another Server instead (without instance).

Real solutions are welcome.
