How to write a compiler for .NET?

[Zingam]

Since I'm interested in formal languages I've decided to write a simple
compiler for .NET for my studies.
I would like to be able to use the .NET class library too (especially
windows forms).

Could you give me an idea where should I start from? Probably I have to
qualify myself as a beginner, so too advanced stuff might be not clear
to me yet. What would you recommend in that case?

Thank you!

so too advanced stuff might be not clear to me yet.

I'm not sure, but writing a compiler always was 'advanced stuff'...

For .NET compilers, it is best to start learning
the CLR and MSIL:

Zingam,

Thomas and Jay gave you reference to good material, so you want to check
those out to begin with. I am working on a compiler targeting the .NET
Framework too, and if you already have some experience with writing
compilers you shouldn't have too many problems. The MSIL is very powerful
and way easier to target than a regular CPU.

I would recommend you to read John Gough "Compiling for the .NET Common
Language Runtime (CLR)"
(http://www.phptr.com/browse/product.asp?product_id={1590B1B8-35AB-484B-B231
-6D40E8D2A60D}), it's a little too much academic here and there but it was a
great source of information. I would also recommend you to read Jason Bock
"CIL Programming: Under the Hood of .NET"
(http://www.apress.com/book/bookDisplay.html?bID=88) if you are interested
in the results produced by different compilers (mainly C# and VB.NET), which
can be a good source of tips.

Don't forget the good old ILDASM (part of the .NET Framework SDK), and Lutz
Roeder "Reflector for .NET" (http://www.aisto.com/roeder/dotnet/). Reverse
engineering is very useful when you are not sure how to implement a
particular feature of your language.

HTH,

Gabriele
