Solution for this is installing build tools.

Open Poershell with Administrator privilages
Run following command:

npm install -g windows-build-tools

Unfortunately this must be called after VisualStudio Update :(

Docker Tips

jacek@kleczkowski.info — Mon, 15 Jan 2018 09:15:26 GMT

1. Cleaning docker unused images

docker images --no-trunc -aqf "dangling=true" | xargs docker rmi

2. Run docker with socket and tcp endpoint

#edit /lib/systemd/system/docker.service and change line starting with ExecStart

ExecStart=/usr/bin/dockerd  -H unix:///var/run/docker.sock -H tcp://0.0.0.0:2376 --dns 8.8.8.8 --dns 8.8.4.4

#save file and run following commands

systemctl daemon-reload
service docker restart

No executable found matching command "dotnet-watch"

1. Check if You have csproj inside directory of command execution

2. Check if there is a reference to the "watcher" tool in the project file (csproj)

<ItemGroup>
    <DotNetCliToolReference Include="Microsoft.DotNet.Watcher.Tools" Version="2.0.0"/>
</ItemGroup>

and then execute

dotnet restore
