HelloWorld由Windows .NET成功启动，但未由MONO成功启动

Question

I've installed mono on my 64-bit Windows 7 using:

• mono-3.2.3-gtksharp-2.12.11-win32-0.exe
  from go-mono download page

in directory (without spaces in path) changed according to Jim Gomes' advice

Successfully run first two examples

• Console Hello World
• Gtk# Hello World

from Mono Basics article.

But the 3d example "WinForms Hello World" is compiled without errors and run from Windows (by double-clicking in Windows Explorer) successfully but running:

mono hello.exe

from "Mono-3.2.3 Command Prompt" window produces the errors listed below (note that first two examples including a window of second example was launched successfully from command prompt invoking through mono ... )

What is the problem and how to overcome it?

UPDATE
According to mentioned article "Mono Basics" I compiled the 3d example "Winforms Hello World" with gmcs hello.cs -pkg:dotnet .

BTW, where is that dotnet package located?
Is it in directory with the same name? I do not have a single dir with exactly such name dotnet under Mono-3.2.3 dir

The errors produced by running mono hello.exe from "Mono-3.2.3 Command Prompt"

Answer 1

I have encountered this problem.

I think this is mono's bug.

If you installed mono in C:\\Program Files (x86)\\Mono-3.2.3\\etc\\mono

Find the 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 this problem will be solved.
