c# - HelloWorld is successfully launched by Windows .NET but not by MONO -

-

i've installed mono on 64-bit windows 7 using:

in directory (without spaces in path) changed according jim gomes' advice

successfully run first 2 examples

  • console hello world
  • gtk# hello world

from mono basics article.

but 3d example "winforms hello world" compiled without errors , run windows (by double-clicking in windows explorer) running: 

mono hello.exe

from "mono-3.2.3 command prompt" window produces errors listed below (note first 2 examples including window of second example launched command prompt invoking through mono ...)

what problem , how overcome it?

update
according mentioned article "mono basics" compiled 3d example "winforms hello world" gmcs hello.cs -pkg:dotnet.

btw, dotnet package located?
in directory same name? not have single dir such name dotnet under mono-3.2.3 dir

the errors produced running mono hello.exe "mono-3.2.3 command prompt"

i have encountered problem.

i think mono's bug.

if installed mono in c:\program files (x86)\mono-3.2.3\etc\mono

find file c:\program files (x86)\mono-3.2.3\etc\mono\config

change line 29-30:

<dllmap dll="gdiplus" target="/tmp/install/lib/libgdiplus.so" /> <dllmap dll="gdiplus.dll" target="/tmp/install/lib/libgdiplus.so" />

to:

<dllmap dll="gdiplus" target="/tmp/install/lib/libgdiplus.so" os="!windows" /> <dllmap dll="gdiplus.dll" target="/tmp/install/lib/libgdiplus.so" os="!windows" />

and problem solved.
