Create new Projects with 'x new'

All ServiceStack Projects can be created using the .NET Core x dotnet tool:

Install #

Apple M1 #

Install on Apple's new M1 Pro and M1 Max ARM chips with:

Update #

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

All features from the cross-platform x dotnet tool are also available from the .NET Core Windows Desktop app tool:

Usage #

To view a list of projects run:

Where it will display all repositories in .NET Core, .NET Framework and ASP.NET Core Framework GitHub Orgs:

Usage #

$ x new `<template>` `<name>`

For example to create a new Vue Single Page App, run:

Alternatively you can write new project files directly into an empty repository using the Directory Name as the ProjectName:

$ git clone https://github.com/<User>/<ProjectName>.git
$ cd <ProjectName>
$ x new vue-spa

Or download a customized project template from our Getting Started Page:

Modernized Project Templates #

The ASP.NET Core Project Templates have been upgraded to use the latest external dependencies and have all been rewritten to take advantage of the ServiceStack Features added in this release, namely:

• Modular Startup - ASP.NET Core Apps can take advantage of the modularity benefits and extensibility of mix features
• Navigation Items - Simplified maintenance and dynamic navigation items rendering using Navigation controls
• Auth Enabled - Integrated Auth including dynamic menu, protected pages, auth redirect flow inc. Forbidden pages
• SVG - Pre-configured to use svg/ folder, ready to drop in your App's assets and go
• Optimal Library Bundles - CSS/JS bundles are split into optimal hashed library and frequently changing App bundles
• SSL - As it's recommended for Web Apps to use SSL, all templates now use https://localhost:5001 and configured to use Same Site Cookies by default

Auth Enabled Project Templates #

Most Project Templates are now integrated with Credentials Auth and Facebook, Google and Facebook 3rd Party OAuth providers, complete with protected Pages and Services and auth redirect flow to Sign In and Forbidden pages.

Create Customized Projects with mix #

All new projects can be further customized with mix dotnet tool to mix in additional "layered" features.

Creating new .NET 5 projects #

If you're not yet ready to move to .NET 6 you can still create new projects of older versions of the .NET Core templates.

Which can also be created from our online Project builder at: servicestack.net/start?tag=net5

Otherwise our .NET Core project templates have had their last .NET 5.0 version tagged with net5 which can be installed with the x tool by using the full URL of its Source Code .zip archive in place of the Template name, e.g:

Creating new projects of older Template versions #

To install any other version, explore each released Project Template version by going to its GitHub Projects /releases page, e.g. /web/releases then clicking on the Release <tag> to explore its contents.

Once you know which release you want to create a new project of, e.g. for the web template /v27 was the last release to target net5.0.

Use its full URL of its Source Code .zip archive in place of the Template name, e.g:

Alternatively if it's easier you can download the Release Source Code archive manually:

https://github.com/NetCoreTemplates/web/archive/refs/tags/v27.zip

Then either rename the project and folder names manually or copy over the original source files you want into your existing solution.

Using older mix features #

All mix features have been rewritten to use .NET 6's new HostingStartup model going forward, to help with migration please refer to the mix diff showing how each of the existing mix configurations were converted to the new model.

To support older projects the Existing ModularStartup configuration can still be used for when running on earlier .NET Core runtimes with the mix tool by changing the gist Id in the MIX_SOURCE Environment Variable, e.g:

Which will chance to use the older mix Modular Startup configuration as its source.

Why a new project template system? #

It's not often that a tool causes enough friction that it ends up requiring less effort to develop a replacement than it is to continue using the tool. But this has been our experience with maintaining our VS.NET Templates in the ServiceStackVS VS.NET Extension which has been the biggest time sink of all our 3rd Party Integrations where the iteration time to check in a change, wait for CI build, uninstall/re-install the VS.NET extension and create and test new projects is measured in hours not minutes. To top off the poor development experience we've now appeared to have reached the limits of the number of Project Templates we can bundle in our 5MB ServiceStackVS.vsix VS.NET Extension as a number of Customers have reported seeing VS.NET warning messages that ServiceStackVS is taking too long to load.

Given all the scenarios ServiceStack can be used in, we needed a quicker way to create, update and test our growing 47 starting project templates. In the age of simple command-line dev tools like git and .NET Core's light weight text/human friendly projects, maintaining and creating new .NET project templates still feels archaic & legacy requiring packaging projects as binary blobs in NuGet packages which become stale the moment they're created.

How it works #

GitHub powered Project Templates #

Especially for SPA projects which need to be frequently updated, the existing .NET Project Templates system is a stale solution that doesn't offer much benefit over maintaining individual GitHub projects, which is exactly what the dotnet-new npm tool and now x new .NET Core are designed around.

Inside dotnet-new and x new is an easier way to create and share any kind of project templates which are easier for developers to create, test, maintain and install. So if you're looking for a simpler way to be able to create and maintain your own value-added project templates with additional bespoke customizations, functionality, dependencies and configuration, using x new is a great way to maintain and share them.

Using GitHub for maintaining project templates yields us a lot of natural benefits:

• Uses the same familiar development workflow to create and update Project Templates
• Git commit history provides a public audit trail of changes
• Publish new versions of project templates by creating a new GitHub release
• Compare changes between Project Templates using GitHub's compare changes viewer
• Browse and Restore Previous Project Releases
• End users can raise issues with individual project templates and send PR contributions

A quick way to get started is to fork one of the existing .NET Project Templates like the web or empty templates.

Always up to date #

Importantly end users will always be able to view the latest list of project templates and create projects using the latest available version, even if using older versions of the tools as they query GitHub's public APIs to list all currently available projects that for installation will use the latest published release (or master if there are no published releases), which if available, downloads, caches and creates new projects from the latest published .zip release.

Just regular Projects #

Best of all creating and testing projects are now much easier since project templates are just working projects following a simple naming convention that when a new project is created with:

$ x new <template> ProjectName

Install directly from your GitHub repo #

To create projects from your own GitHub projects use its qualified user/repo name, e.g:

$ x new <user>/<repo> ProjectName

Replaces all occurrences in all text files, file and directory names, where:

• My_App is replaced with Project_Name
• MyApp is replaced with ProjectName
• My App is replaced with Project Name
• my-app is replaced with project-name
• myapp is replaced with projectname
• my_app is replaced with project_name

The tool installer then inspects the project contents and depending on what it finds will:

• Restore the .NET .sln if it exists
• Install npm packages if package.json exists
• Install libman packages if libman.json exists

That after installation is complete, results in newly created projects being all setup and ready to run.

Available project templates #

One missing detail is how it finds which GitHub repo should be installed from the <template> name.

This can be configured with the APP_SOURCE_TEMPLATES Environment variable to configure the x tool to use your own GitHub organizations instead, e.g:

APP_SOURCE_TEMPLATES=NetCoreTemplates;NetFrameworkTemplates;NetFrameworkCoreTemplates

Optionally you can display a friendly name next to each Organization name, e.g:

APP_SOURCE_TEMPLATES=NetCoreTemplates .NET Core C# Templates;

x new will then use the first GitHub Repo that matches the <template> name from all your GitHub Sources, so this does require that all repos have unique names across all your configured GitHub Sources.

These are the only sources x new looks at to create ServiceStack projects, which by default is configured to use NetCoreTemplates, NetFrameworkTemplates and NetFrameworkCoreTemplates GitHub Organizations, whose repos will be listed when running:

Creating new Legacy Project Templates #

By Setting APP_SOURCE_TEMPLATES environment variable to LegacyTemplates you can can use the x tool to browse and create new legacy project templates, e.g:

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

$ sudo vi /etc/ssl/openssl.cnf

:%s/^ssl_conf/#&/
:wq

$ sudo update-ca-certificates --fresh

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

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