Cannot GET /

[DaveSweeton]

I cloned the repo, built the app, and executed "dotnet run". When a browse to http://localhost:5000/, I just get an error page that says: Cannot GET /.

I get the same results when running from visual studio.

Hi, can you confirm you have both ASP.NET Core and Node.js installed with correct versions?
My versions installed:

dotnet --version
3.1.101

node --version
v12.13.0

Visual Studio 2019 v16.4.3
Can you please share more info what happens when you run dotnet run command? Standard working output is:

My current .net version is 3.1.100 and node is v10.16.3.

I'm not sure what's different today, but I'm now able to run both from VS and from dotnet run! I didn't change any code, just rebooted my computer.

Thanks for your help, and sorry for the strange report.
