Update for .net 5? Is this dead? #74

I went to teach a friend about LINQ and I thought this would be the perfect way, run .net in the browser, execute your linq queries, see what happens - it should be perfect, right?

Nope.

dotnet tool install -g dotnet-try
git clone https://github.com/dotnet/try-samples
cd try-samples
dotnet run

ok, everything looks good so far...but not a single sample will actually execute. I click on the play button, it spins for a while, then a red box shows up at the bottom of the code window. If I look at my dev tools console it's full of errors. :( Hundreds of them, just like this (see below).

What am I doing wrong? Isn't this supposed to just work? I guess I'll need to find some other way to teach my friend about LINQ. ☹️
