This is an URL I know of that extensively talks about writing MSIL code
directly: http://www.vijaymukhi.com/documents/books/ilbook/ilbook.html

Is it possible to wite IL programs directly? If so, how to write it?

How, is a long process? The tool to assemble il into dll is ilasm.exe.
You can practice by using "ildasm.exe" and disassemble a dll into il and
then use ilasm to reassemble the il into dll.
