Sometimes I try to write a little bit of IL code or modify bits and pieces here and there (specially modify IL generated from say C# code).
The problem is writing up the complete IL that compiles into an exe is a pain (specially because my usage is to tweak them). To work around this I use the following flow which I thought I'd share
the neat part is the /out parameter which makes ildasm dump a single IL for the entire code. At the beginning I used to try patching the code up by copy-pasting from ILDASM UI which show separate IL code for every method :(
