Error trying to create a webapi in Visual Studio Code

Question

I get this message in the terminal:

error NU1100: Unable to resolve 'Swashbuckle.AspNetCore (>= 5.6.3)' for 'net5.0'

I tried to run dotnet restore as it reccomended but it will not restore

Answer 1

Just got the same issue on a clean machine. I managed to fix it running the command:

dotnet nuget add source --name nuget.org https://api.nuget.org/v3/index.json

After that, create/restore your project and it should work.

source

Answer 2

I was trying to build an API using dotnet CLI as well, for a couple of days now. Ended up getting no answer from microsoft, or another source of info.

Anyways, the only way I made it work was unstalling .NET SDK 5.0.203 (Latest version for the time being), and installing .NET SDK 5.0.101, and thats it, new api command works flawlessly.
