Why some nuget packages can not be used in net core?
Such as 'Def.1.1.1', which I successfully referenced but could not use.
The error is:
Compilation error (line 13, col 21): The name 'Def' does not exist in the current context.
The site shows that the package is "on disk", but '/usr/nugetCache/def' does not contain 1.1.1.
Is there a problem?

Support null check operators
Allow the compilation of null check operators i.e. DataSet?.Tables.Count. Currently the "?" screws up everything and a compilation error is received:
Code:
System.Data.DataSet ds = null;if (ds?.Tables.Count == 0 || ds?.Tables[0]?.Rows.Count == 0)
{
Console.WriteLine("True");
}
else
{
Console.WriteLine("False");
}Errors:
Compilation error (line 8, col 10): Invalid expression term '.'
Compilation error (line 8, col 11): Syntax error, ':' expected
Compilation error (line 8, col 35): Invalid expression term '.'
Compilation error (line 8, col 36): Syntax error, ':' expected
Compilation error (line 8, col 46): Invalid expression term '.'
Compilation error (line 8, col 47): Syntax error,…3 votes -

Solution/Project Explorer
I would like to be able to create projects that contain multiple files so that I can create tutorials to teach student.
The MVC project type for example allows for multiple files. but they are all together on screen and I can't close one down to focus on say the controller.VS Code uses Theia https://www.theia-ide.org/index.html - Perhaps you could also use this in your UI?

Be able to include import a Github repository
This would really help to make samples of bugs / issues in a repository. One could import all the files of a repository, then write a "Test" that fails and the owner of the repository could then check out why it fails easily.
See for example me manually uploading the files in a competitors product:

Specify timezone for snippet
Sometimes I need to check a code that works with local timezone which should be different from UTC. It would be great to have an ability to specify timezone in that cases. Thank you!

Bug(?)
I was coding something and had some code to tell the user to press enter to continue. I did not want to keep writing it, so I copy and pasted it. However, this made my code go wonky. I had a switch later in the program and I was testing it out making sure it worked. I had copied and pasted the code after the switch, and this is where it gets weird... every time I ran it, it would go back to where I copied the code from and rerun the switch. I don't know why it happened but…

Debugging
Allow the usage of debugging such as stepping into a function, out of a function, run, memory mapping, local variables and the whole nine yards. It is vital if you don't want users to write constantly Console.WriteLine() statements.
Kindly, add debugging!
