SharpDevelop Community

Hello,

I installed both 3.2 and 4.2 versions of #develop and I cannot debug my projects with the 4.2 one: it will never stop on any breakpoints!

[edit]I tested also with 4.1 version, the same story: debugging does not work.[/edit]

The same project with the same breakpoints will behave correctly with the 3.2 version ...

Anyone is aware of this issue?

If yes, is there any workaround?

Thank you in advance !

Best regards,

Hello SoftExpert,

I just tested a simple console project in both 3.x and 4.x. The project was created with 3.x and targets .NET 3.5. The debugger properly breaks at breakpoints in both versions of SharpDevelop.

Do you use any special libraries? Can you post the configuration of your environment and the projects you are using?

regards,

Siegfried

Hello Siegfried,

Thank you for you reply; I have a VM with Windows 2003 R2 and .NET 3.5 with latest updates and, ofcourse, 4.0

I use SharpDevelop for quite a while and I never had problems with it (nice piece of software, by the way !)

Now, I created (with SD 3.2) a .NET 3.5 project for integrating a component into a Kofax Capture Scan module.

The component is declared as COMVisible and CLSCompliant. I can debug it quite easily with SD 3.2 ...

Now, the same project is loaded in SD 4.2 and compiles OK; no conversion is performed, so that I can open it with SD 3.2; when trying to debug it wil not stop to breakpoints as if they are not set.

The .NET wersion used by Kofax Capture is 3.5 if I'm not mistaken; also SD 4.2 should support it, no?

I created a console project and SD 4.2 will stop at breakpoints as it should; i got the following exception though ...

For confidentiality reasons I cannot post the code of my project; but I can setup a generic one if you like; then you also need to have the Kofax Capture environment, which is another story ... But I can give you remote access to my dev machine - I used mikogo and it does the job just right. Please let me know if you are interested ...

Thank you for your support!

Hello again Siegfried,

I just found the following reference : http://blogs.msdn.com/b/greggm/archive/2010/06/08/debugging-a-net-framework-2-0-3-0-3-5-class-library-with-vs-2010.aspx

Seems to be the same problem as I have; could there be a workaround in SD for it? Maybe an element in the project options (a dropdown list) with the preferred debugger version  ( if it is possible to force a debugger version ) ...

For the moment, the workaround is to create the myapp.exe.config file

< ? xml version="1.0" >
<configuration>
    <startup>
        <supportedruntime version="v2.0.50727">
    </supportedruntime></startup>
</configuration>

Best regards,

Hi,

sorry for not answering for a while. I am not really a debugger expert, so I might not be able to help you a lot. So your problem is, that the "main" project is compiled to .NET 4 and a precompiled library is targetting 3.5? I doubt this should be a problem, because when we have some projects inside SharpDevelop that target previous .NET frameworks but are run on CLR 4.

I am glad you found a simple workaround in your case.

regards,

Siegfried
