.net - Compile C# Application to native executable -


i know question came few times before, not find answer our simple case:

is there free tool compiles small .net c# application native executable?

what found far expensive tools strip down .net framework , compile executable, thats no neccessarry in our case. installing .net framework no problem, want precompile c# project user can not decompile il code security reasons. .net obsucator not enough, have sensitive code sections.

mono-aot not option, needs have mono installed on target machine undersood.

ngen.exe seems closest need, how can distribute output file? seems include il code well, says "whenever ngen-generated image run in incompatible environment, .net framework automatically reverts using jit".

are there practical workflows scenario?

edit2: wonder why question closed...

the solution mkbundle mono project:

i found shell script compiles .net application mono's mkbundle standalone native executable , modified latest versions, of may 2013 can use script follows:

https://gist.github.com/tebjan/5581296

1.) install cygwin , make sure select following packages: - gcc-mingw - pkg-config - mingw-zlib1 - mingw-zlib-devel

2.) install mono release package: "mono windows, gtk#, , xsp"

3.) download script , place besides application , modify fit environment (read comments in file carefully).

4.) open cygwin , navigate output folder of application executable , scipt lies, e.g. yourproject/bin/release

5.) execute script command: ./mkbundle_cygwin.sh

troubleshooting: if bundled executable not work, make sure original .net application works on mono. can test calling mono.exe , pass .net app or installing xamarinstudio , running project there (make sure set mono runtime).

for particular case, seems simplest approach put magic bytes separate native dll, , have managed code use p/invoke retrieve them. meets 2 requirements have mentioned:

  • separate magic data code uses it
  • keep magic data out of .net assemblies

i have detailsview control on page used edit various fields of record, works in respect. i looking way add 1 column (and if works, why not more) right, absolutely read-only, show same fields of record comparison purposes. i aware there no obvious way such thing out of box detailsview . have looked other controls (transposed gridview , recommended formview , listview ), nothing satisfies. have special data binding setup using detailsview , can't out of without losing features. anyone on how "hack in" additional columns (for display only) on detailsview ? the solution have now, use second detailsview , visible set false in aspx. in code, make sure databind hidden detailsview hosts data third column first, initial detailsview named itemdetails . and in item created event, pass third column html rendering of hidden controls (in last code block) : protected void itemdetails_itemcreated(object sender, eventargs e) { if (dataite
