I honestly just winged it. I came from C++ so you're in a much better position to learn .NET than I was. There's little need to get into the syntax. You can pretty much just wing it. It's just OOP after all. You could probably look for some crash courses so that you can speedrun the language differences but other than that, you'll do just fine using the official documentation.

Microsoft has free resources for their frameworks.
