A Source Generator is a new kind of component that C# developers can write that lets you do two major things:
- Retrieve a Compilation object that represents all user code that is being compiled. This object can be inspected and you can write code that works with the syntax and semantic models for the code being compiled, just like with analyzers today.
- Generate C# source files that can be added to a Compilation object during the course of compilation. ...
What is code generator and how it works?

Are code generators good for software engineering?
Code generators are ubiquitous in software engineering and when they are understood, they can lead to all sorts of benefits. From scaffolding generation like in Ruby on Rails, to REST API generation like Swagger Codegen, there are a lot of useful code generation tools available. However, there is a dark side to code generators.
How can I use a source generator to inspect user code?
You can inspect user code with all of the rich metadata that the compiler builds up during compilation, then emit C# code back into the same compilation that is based on the data you’ve analyzed! If you’re familiar with Roslyn Analyzers, you can think of Source Generators as analyzers that can emit C# source code.
How do code generators work?
From a board perspective, this is pretty much how code generation works. A template is invoked to generate some code with some data being passed to the template for use. The template will have some sort of way to process the data and usually provide a way to do standard programming things like loops and selections.

Common scenarios
There are three general approaches to inspecting user code and generating information or code based on that analysis used by technologies today:
Get started with source generators
In this guide, you'll explore the creation of a source generator using the ISourceGenerator API.
Next steps
The Source Generators Cookbook goes over some of these examples with some recommended approaches to solving them. Additionally, we have a set of samples available on GitHub that you can try on your own.
What is code generation?
Code generation process is iterative, developers can add databound controls, user interface pages and databases tables to the application in any order. The generated base classes can be customized, and existing or third party code assets can be imbedded. Effects of changes can be easily seen by just regenerating the application at any time. With each new iteration, all the extensions and customizations are automatically preserved. Some of the most commonly used code generation tools are:
What is an application generator?
Application generators are the code generation tools that offer significant advantages. Application generator helps create application programs that can run on a particular platform. These generators take basic set of inputs and jumpstart the application development process by generating basic code which is more bug-free and reliable as compared to the hand-written code. This also makes the testing and bug-fixing much easier. Sophisticated application generators deliver code which is consistent with the pre-decided set of functionality. Additionally, these generators can generate complex web pages including reports, forms, filter and several other advanced navigation features. The generated code is comparable to the one written by the senior developers. Passive code generators create code and then have nothing to do with the project. Active code generators create code and keep track of the generated code during its lifecycle. The modern code generators are capable of:

Is writing code a waste of time?
With such pressing conditions, writing unnecessary code is painful, and a waste of time. It can be quite unproductive for any organisation to use senior development resources to work on time-intensive, low-level hand coding tasks. At the same time, there is usually insufficient junior staff, and even when they are available, they may not be trained enough for coding or code reviews.
How does source generator help?
Source Generators can improve performance in ways that aren’t limited to reflection at run time to discover types as well. Some scenarios involve calling the MSBuild C# task (called CSC) multiple times so they can inspect data from a compilation. As you might imagine, calling the compiler more than once affects the total time it takes to build your app! We’re investigating how Source Generators can be used to obviate the need for juggling MSBuild tasks like this, since Source generators don’t just offer some performance benefits, but also allows tools to operate at the right level of abstraction.
What is a Source Generator?
A Source Generator is a piece of code that runs during compilation and can inspect your program to produce additional files that are compiled together with the rest of your code.
What are the three approaches to inspecting user code and generating information or code based on that analysis used by answer?
Today, there are three general approaches to inspecting user code and generating information or code based on that analysis used by technologies today: runtime reflection, IL weaving, and juggling MSBuild tasks . Source Generators can be an improvement over each approach.
What is the difference between a source generator and a compiler?
The key difference is that analyzers ultimately emit diagnostics that can be used to associate with a code fix. Source Generators ultimately emit C# source code that is added to a compilation.
How are source generators similar to analyzers?
Source Generators are similar to analyzers, since both are compiler features that let you plug into a compilation. The key difference is that analyzers ultimately emit diagnostics that can be used to associate with a code fix. Source Generators ultimately emit C# source code that is added to a compilation. There are several other differences discussed in the design document.
What are the characteristics of source generators?
Another characteristic of Source Generators is that they can help remove major barriers to linker-based and AOT (ahead-of-time) compilation optimizations. Many frameworks and libraries make heavy use of reflection or reflection-emit, such as System.Text.Json, System.Text.RegularExpressions, and frameworks like ASP.NET Core and WPF that discover and/or emit types from user code at runtime.
Why does ASP.NET Core use reflection?
For example, ASP.NET Core uses reflection when your web service first runs to discover constructs you’ve defined so that it can “wire up” things like controllers and razor pages. Although this enables you to write straightforward code with powerful abstractions, it comes with a performance penalty at runtime: when your web service or app first starts up, it cannot accept any requests until all the runtime reflection code that discovers information about your code is finished running! Although this performance penalty is not enormous, it is somewhat of a fixed cost that you cannot improve yourself in your own app.
What is code generator?
Code generators are ubiquitous in software engineering and when they are understood, they can lead to all sorts of benefits. From scaffolding generation like in Ruby on Rails, to REST API generation like Swagger Codegen, there are a lot of useful code generation tools available.
How does code generation work?
Code generation is pretty simple and you are likely already doing it. The easiest case to show is how most people generate HTML for websites . In almost all modern web application frameworks (Rails, CakePHP, Grails, and sooo many more) there is some sort of template mechanism.
Is code generator a double edged sword?
This makes code generators a double-edged sword. They have both favourable and unfavourable qualities. There is also an interesting history of code generators that has cemented some peoples opinions. But if we all got stuck in the failings of the first attempts at a new technology, the human species may not have evolved past the Stone Age. The work done in this area has come a long way in recent years and is showing some pretty amazing results.
Do you need a code generator for a codebot?
The reality is that at some point we need a codebot to write some code. In the model-driven engineering world we call this a model-to-text (M2T) transformation. Or in the history of our industry we have called this a code generator. Or if you like, a templating mechanism. So, on this level I concede. We use a code generator in the final step for a codebot writing code. Like Wild E. Coyote, if you can’t beat em, join em.
Is there a dark side to code generators?
And when their power is used without constraint, developers can go down a path that leads to all sorts of disadvantages. Like when developers lose control of their source code with low code tools such as OutSystems, life can get pretty frustrating quickly.
Can Jekyll generate HTML?
In the above simple example using Jekyll, it was shown that we could generate a HTML page with the title dynamically generated. But it is possible to pass far more sophisticated input to the template. For example, convention over configuration frameworks like Rails use the active record pattern to generate full stack software application based off the database schema. This is a definite step in the right direction.
