Inject C# code before build

Question

How to inject a new code in existing C# code (not MSIL) before compiling, but not change .cs file?

No, it doesn't help. I need to inject a lot of similar code in different properties of classes. — Aleksandr Vishnyakov, Mar 28 '11 at 20:38

You can use the Text Template Transformation Toolkit (T4) to handle this type of scenario.

Use T4 templates which write to partial class files. This is the pattern used by Visual Studio--auto-generated code goes in partial files, while your code goes in the main .cs file.

You may take a look at PostSharp.

With PostSharp, I can inject code in runtime, but not before compiling. – Aleksandr Vishnyakov Mar 28 '11 at 20:33
I'm pretty sure PostSharp injects code after compilation, but before runtime. – Giovanni Galbo Mar 28 '11 at 20:38

You says: "I'm pretty sure PostSharp injects code AFTER compilation...", but I need to inject code BEFORE compilation. – Aleksandr Vishnyakov Mar 28 '11 at 20:43
I know, I'm correcting you, "With PostSharp, I can inject code in runtime" – Giovanni Galbo Mar 28 '11 at 20:45
