I'm an experienced developer, but my .net has been mostly webforms and only a little (very customized by that company) mvc. I'm working on learning core. But..I'm kind of confused by the options. Apparently there are things that can be done on core that can run on any platform, but within core there is also 4.7.2 that can only run on MS stuff? And there are razor pages, and mvc pages? I started to do a tutorial and I have vs 2017 but they had 2015, and it said pick .net 5, but I have no 5. Can someone break it down or point me to an article (not MSDN..that just made it worse).
Like what is in what version and what the most obvious options are? Hope that makes sense.

Since a couple of months I'm very into (ASP).Net Core and really love it! Started some hobby/learning projects (console, web api and web apps) and I'm looking for a service to deploy them to the web. I looked at EC2(I already run out of free tier) and Digital Ocean, but for hobby projects they are too expensive for me.

So my question to you, where do you deploy your hobby projects for free or low costs?

I'm a dev with 3 years of experience and I'm making a portfolio to show off my skills. It would be super cool if you could show me yours.

Hi! I was wondering if there was a way to get Visual Studio (or Rider) to download the source files for .NET Core and ASP.NET Core so that my IDE would navigate to the sources. I'm used to using Java, Go, or Python and navigating to the source to see how things work. Microsoft has great docs and Rider's decompiler is ok, but I wish I could simply navigate to the source code. Visual Studio seems to just want to take me to the Assembly Browser which is less than ideal.

C# and .NET Core seem really nice, but it would be helpful to be able to navigate around the sources.

Oh, I'm on a Mac and have tried to get this working with Visual Studio for Mac, Rider, and VS Code.

I wish to create a web application on my MacBook.

Is it possible for me to use ASP.NET MVC 5 on Mac?
