ServiceStack's .NET Core Utility Belt

Our web (and app) .NET Core tools are a versatile invaluable companion for all ServiceStack developers where it’s jam packed with functionality to power a number of exciting scenarios where it serves as a Sharp App delivery platform where they can be run as a .NET Core Windows Desktop App with app or as a cross-platform Web App launcher using web and we’ve already how it’s now a #Script runner with web run and into a Live #Script playground with web watch.

They also contain all features from our @servicestack/cli npm tools so you’ll no longer need npm to create ServiceStack projects or Add/Update ServiceStack References.

To access available features, install with:

$ dotnet tool install --global web 

Or if you had a previous version installed, update with:

$ dotnet tool update -g web

The Windows-only app tool has better integration with Windows that can power .NET Core Windows Desktop Apps.

Then run web without any arguments to view Usage:

Add/Update ServiceStack References

This shows us we can Add a ServiceStack Reference with web <lang> <baseurl> which will let us create a TypeScript Reference to the new World Validation App using its ts file extension alias:

$ web ts http://validation.web-app.io

Saved to: dtos.ts

Or create a C# ServiceStack Reference with:

$ web cs http://validation.web-app.io

Saved to: dtos.cs

To update run web <lang> which will recursively update all existing ServiceStack References:

$ web ts

Updated: dtos.ts

Create new Projects with web new

See web new for info on how to create new projects.

Mix/Match ASP.NET Core projects with web +

See web + for how to mix/match gists to “layer on” functionality to create customized ASP.NET Core projects.


web: command not found

If after installing the dotnet web tool it fails with bash: web: command not found you’ll need to add dotnet tools to your PATH which you can do in Linux Bash with:

$ echo "export PATH=\$HOME/.dotnet/tools:\$PATH" >> ~/.bashrc
$ . ~/.bashrc

SSL Connection Errors

To resolve SSL Connection errors you can try commenting out ssl_conf = ssl_sect, e.g:

$ sudo vi /etc/ssl/openssl.cnf

Comment out line in vi using a # prefix, write changes and quit:


If that doesn’t resolve the issue you can try updating the local ca-certificates:

$ sudo update-ca-certificates --fresh

Or try updating the SSL_CERT Environment variables before running the tool again:

export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt
export SSL_CERT_DIR=/dev/null

Finally you can try running the web tool with the --ignore-ssl-errors switch, e.g:

$ web new vue-lite VueLite --ignore-ssl-errors
