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:

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…
