Hello,

again :-)

Prerequisite: 

1) wine-0.9.49 (or GIT)
2) successful installation of .NET 2.0 Framework
3) "l_intl.nls" copied from windows installation to wine system32
4) PEB loader lock patch from http://bugs.winehq.org/attachment.cgi?id=9195

----

With that stuff in place, starting .NET gui apps will immediately lead to a
crash.

Wow .. CLR exception for now :-)
Lets see what kind ...

Exception type: System.ArgumentException
Message: Only TrueType fonts are supported. This is not a TrueType font.

Now thats some kind of useful information (although the message is slightly
misleading as found later).
Obligatory CLR stack:

Ok, native gdiplus that doesn't like the way  truetype fonts are currently
installed on my system.
Unfortunately you can't use wine gdiplus (builtin) at this point because there
is too much API missing.
.NET "fixes" this issue by using LoadLibraryEx() + direct load path, preventing
builtin load first.

Bascially it enumerates the registry (SOFTWARE\\Microsoft\\Windows
NT\\CurrentVersion\\Fonts) keys and searches "c:\\windows\\fonts" (SearchPathW)
according what it found in registry.
Following keys are queried too: "SOFTWARE\\Microsoft\\Windows
NT\\CurrentVersion\\FontLink\\SystemLink" and "SOFTWARE\\Microsoft\\Windows
NT\\CurrentVersion\\FontSubstitutes"

Fix1: copy the registered truetype fonts from your share\wine\fonts whatever to
windows\fonts.
Be aware .NET apps might use more font variants so it might look very crappy if
only few (fallbacks) are used.

Fix2: copy/install the default windows truetype fonts (all ttf) to your wine
windows\fonts folder and register them in registry (if not done by installer).
You might export "HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Font*" keys
for easier game.

This should fix the font issue and give apps the look'n'feel as in windows.

Stay tuned, more goodies to come ...
