Topic: Is anyone using ILSpy?

[TheMaster]

The beta of version 2.0 has been online for a few months and
after playing with it, I'm ready to say 'adios Reflector'.

There's even a version that runs on Metro.

Best of all, its open sourced and you can hack on it to your heart's content.

Thanks for the heads up Tony - an alternative is handy.
I've had a look at dotPeek from JetBrains ... good, but not up to Reflector yet.

Speaking of Reflector, here's some interesting observations:

Red Gate Reflector some times do not show code ofuscated with Red gate Smartassembly. Why?

Especially when looking at acdbmgd.dll & acmgd.dll
 
JustDecompile is hands down the best at decompiling the code to this 

 
 
 
Thanks for that link!!
Wish I would of known about this before I paid for Reflector.

Sorry. I do not understand, perhaps because I do not speak English : Il & C#

[exmachina]

  Ok. You're right

[TheMaster]

Refector is only accurate with IL produced by the Microsoft C# compiler.

IL produced via any other means (e.g., another language) may not
be accurately decompiled.

Hate to disagree

Can you debug managed code with JustDecompile ?

ILSpy 2.0 (beta) is a debugger as well as a decompiler.

You can set breakpoints, launch an executable or attach
to a running process, and step through any code in any
assembly that's loaded, regardless of whether it is your
code, the .NET framework, or AutoCAD's managed runtime.

When a breakpoint is hit, you can examine the call stack,
see the values of  arguments, etc. (no locals/watch window
yet, but that's planned).

Also, it looks like Telerik still has some work to do.

Were you using the assemblies from the SDK or the production

The ones located in same location as acad.exe not the sdk's or ones that are just the signatures.

Thanks Tony.

Why does anyone need to debug 3rd party assemblies?

Why does Visual Studio allow you to debug .NET framework code?

Why does Visual Studio allow you to debug .NET framework code?

I do not know. If someone has an (real life) example , please send it.
Thanks.

Microsoft made the source available for debugging so that if you need to know what the framework is doing when you call one of its APIs, you can step into the source code to find out.

What about pdb files and others files like this?. In any case, i respect your opinion but i do not understand what may be the purpose of debugging that:
Debugging System.Drawing.Graphics.DrawString

[Jeff H]

Many reasons and on one hand you have people checking and testing your code for free.
 
Using your example lets say you keep getting a exception that your brush is null and you use a decompiler to look at code.

Code - C#: [Select]

1.         public void DrawString(string s, Font font, Brush brush, RectangleF layoutRectangle, StringFormat format)
2.         {
3.             if (brush == null)
4.             {
5.                 throw new ArgumentNullException("brush");
6.             }
7.             if ((s != null) && (s.Length != 0))
8.             {
9.                 if (font == null)
10.                 {
11.                     throw new ArgumentNullException("brush");
12.                 }
13.                 GPRECTF layoutRect = new GPRECTF(layoutRectangle);
14.                 IntPtr handle = (format == null) ? IntPtr.Zero : format.nativeFormat;
15.                 int status = SafeNativeMethods.Gdip.GdipDrawString(new HandleRef(this, this.NativeGraphics), s, s.Length, new HandleRef(font, font.NativeFont), ref layoutRect, new HandleRef(format, handle), new HandleRef(brush, brush.NativeBrush));
16.                 this.CheckErrorStatus(status);
17.             }
18.         }
19.  

You tell microsoft and they can't reproduce it and you send them your code for creating a brush and they can't reproduce it.
 
I do not know if you caught it but I changed the exception for font null check (easily could happen by copying pasting and forgetting to change brush to font)
 
If you debug it you would have noticed that it really was your font that was null. I do not see how people can really say they know what there code is doing without debugging it.

[exmachina]

Maybe I have not understood well (sorry, always i have the same problem because i don't speack...etc), In my opinion:

1- I do not work for Microsoft, much less free. So i have no reason to find/debug their mistakes
2- 33 + 33 = 66. Otherwise the problem is the compiler or languaje implementation=>Look@point 1
3- At this level anyone can be distinguish what is his own fault/bug or that of others, so=>Look@point 1

I have not spent much time with it but at least looks cool, a visualizer plug-in for ILSpy.

... That's pretty neat; I'm sure the Assembly Visualizer will come in handy as I progress with .NET development. :beer:
