I have some issues with my Windows Forms UserControl and am unable to place it in a form. I'm trying to find the problem using design time debugging with devenv.exe but whatever I try, breakpoints are ignored. At first I had the "breakpoint will not be hit, no symbols for this document" warning but I fixed it and now there is no warning.
I know this has been answered may times, but none of these have worked for me and all out of options
Enabling DEBUG constant
Setting debug info to full
Disabling Just my code
Making sure the breakpoint is in the right place to be hit
Making sure I use the debug option before launching
Making sure I'm attached to the right process (there is only one available)
Setting the project as startup
Running VS as an administrator
Disabling Step over properties and operators
Try these:
Make sure that you used Debug configuration to debug your project.
1) reset vs settings under Tools-->Import and Export Settings--> reset vs settings
2) close Vs, delete .vs hidden folder under the solution folder, bin and obj folder.
Also, Windows Forms UserControl project is a class library project, and it cannot set up to debug directly. You should create a console or windows form exe project and then reference the Windows Forms UserControl project, after that, initialize the class with class_name xxx=new class_name();, set a breakpoint on that. At last, set the new exe project as a startup project and then test it.
3) when you are debugging, please enter Debug-->Windows-->Modules and check if your <user_control_project_name>.pdb file is loaded, if not, you could right-click on it to Load Symbols.
I have a solution that launches multiple projects, and I set the launch profile for both to the console app instead of launching in IIS via the Project Properties page.
When I launched the projects individually they launched successfully in the console windows. But when I set multiple startup projects they went back to launching in IIS.
How can I get multiple projects to launch using the correct debug profile?
To set the default launch profile you can re-arrange the debug profiles listed in Properties > launchSettings.json. The first profile in the list will be the one used when launching multiple projects.
As mentioned in the comment of the other answer, it doesn't seems to be true for VS2022. It does not automatically use the first entry in the launchSettings.json list.
You can change the starting project to a single one and switch the debug profile with the small arrow next to the play button in the toolbar one by one. But if you need to do a mass switch, I suggest doing a "search in all files", it's stored in the .csproj.user files:
<ActiveDebugProfile>Docker</ActiveDebugProfile>
Change them all, then reload your solution.
I have a Windows service and I have written Debugger.Attach() in the Onstart method of the service.
When I start the service I get a popup which asks to select the debugger instance.
When I select and press ok, the visual studio comes into focus but shows me "No symbols have been loaded" message.
I followed two steps
1.from here http://geekswithblogs.net/dbutscher/archive/2007/06/26/113472.aspx
While debugging in Visual Studio, click on Debug > Windows > Modules. The IDE will dock a Modules window, showing all the modules that have been loaded for your project.
Look for your project's DLL, and check the Symbol Status for it.
If it says Symbols Loaded, then you're golden. If it says something like Cannot find or open the PDB file, right-click on your module, select Load Symbols, and browse to the path of your PDB.
2 goto Debug-> options and settings ->
under the debugging node -> general ...uncheck "just my code" checkbox
and it worked...
I most commonly see this issue when the build of my project that is running doesn't exactly match the build currently loaded in VS. For example, I build my VS project, then I make some (any) change to a file in the project and save without rebuilding. Then if I run the executable/service/DLL the previously built version will run and since it doesn't match the version I have in VS (thanks to my code change), it won't properly attach.
The specific issue in this case is that the VS debugging PDB file does not match the source code making debugging impossible.
This may not be your issue, but I have seen the "no symbols..." error countless times and it is usually a case of the code being executed not matching the code in VS.
I have a Xcode project that is building a library and I want to be able to debug the library when it is loaded by the main application.
Run and Debug options from Run menu are disabled and if i try to use attach to process option I get "No launchable executable present at path". When looking at Active Executable I see but I don't know how to tell xcode what to run/debug.
So how should I debug the application? I'm looking for something similar to the project configuration of Visual Studio but I wasn't able to locate this option yet.
Add a custom executable to your project.
It is under the Project -> New Custom Executable... menu item.
From there, you can add your application as the custom executable and that will give you the ability to debug the application and the plug-in.
One additional helpful hint; in Xcode's build preferences set up a single common products directory. This will put the symbol files for building your application in the same directory as your application (assuming your main application is one you build) and, thus, you'll be able to step through frames in both your library and your application.
For those using Xcode 4:
Project > Scheme > Edit Scheme...
Select the Run phase > Info
And set an Executable
I cannot get rid of this in my VS 2008 web project when debugging. I've checked that it's in debug mode on the non-web project in question and it's in Active(Debug). Deleted all items in my .NET 2.0 temp folder in Windows. Not sure what else to do here.
Try disabling "Enable Just My Code" in Tools/Options/Debugging/Options.
I had the same problem and discovered that I wasn't outputting my debug info on my build. If you right click on the project and go to 'properties', then select the 'build' tab, on the bottom of the page there's an 'Advanced...' button that will display your setting for you output debug info. Set that to 'full' and the error should go away.
I just ran into this issue, and quickly decided that the other answers posted didn't apply to me.
I'm the owner of the project, and I know it was built with debug information, as well as without optimizations. Furthermore, I'm never happy choosing the disabling of a warning as my first choice. Hiding/ignoring this warning could become an issue in a future debugging session.
Since this only started occurring after I signed the assembly, this clued me in on my quick fix: temporarily remove the strong name of my DLL (and consuming EXE). Voila! Problem solved.
A better, long-term solution, could take the form of adding a post-build action to update the GAC so it has the latest version of the signed DLL.
But for now, I'm happy to move on from this diversion, and continue working on the issue that brought me to this debugging session.
resolved. Deleted all occurences (all projects) of the dll in question.
VS2012, clean and rebuild fixed the issue for me. "Properties" -> "Build" -> Optimize code is unchecked. "Properties" -> "Build" -> "Advanced" -> Debug Info: Full
Check out this link
http://social.msdn.microsoft.com/Forums/en-US/vsdebug/thread/43cb16ba-0759-42ab-8e7d-9f168ace3b6f
try unchecking "Just My Code" in Tools->Options->Debugging->General.
it works for me
Guessing VS 2008 is not rebuilding the dll correctly.
1) Delete all occurrences of the dll
2) Rebuild solution
And that should fix it.
Check your build configuration options. Make sure optimizations are turned off and the DEBUG constant is defined.
If everything else fails, try renaming the Assembly name in the project's properties. This fixed the issue for me.
I get this issue as well, for some reason it's happened 3 or 4 times; I think it must be a Visual Studio 2005 bug/hick up (or at least my installation).
This has worked every time: to fix it I
Right click on my solution and click Properties.
Open Configuration Manager.
Select Debug in the drop down menu (if not already selected).
Uncheck BUILD. Then re-check it.
Rebuild the solution.
Tools > options > Debugging > Symbols > Specify excluded modules
look that if the dll or the exe in the excluded modules list
At least for non-web applications this works:

2 - Allow Debugging...
Due to the nature in which one of the assemblies has been built in your application, you will need to change a few settings to allow the code to be handled by the Visual Studio Debugger.
Right click on any project in question from the solution explorer and select 'Properties'. This will open up the project properties panel giving us access to a great many options for our projects. Navigate to the 'Complile' Tab (or 'Build' if your in a C# environment) and select 'Advanced Compile Options...' from the bottom of the screen. This presents us with a prompt that has two key areas of interest:
1) Optimizations - uncheck 'Enable Optimizations'
2) Generate debug info - Ensure that the option is set to 'Full'
I had this issue with a solution in a certain folder, but if I moved it to another folder or others built it, I didn't get the message. I did the clean, rebuild, and even rebooted and still couldn't get the original to debug without this message. I searched my system for copies of the file causing the error and I found that copies were kept in
c:\User\username\AppData\Local\Assembly\dl3
This was on Win7-64 but will be similar on other Windows OSes. I deleted all of the copies I found there and I no longer get the message. I didn't need to uncheck the "Enable Just My Code".
Also, this was for a WPF app, but I came across this thread in my search so hopefully this will help someone else.
I was able to resolve this issue by following these steps:
Right-click on the Solution (not the Project), and select 'Properties'
In the left panel, select 'Configuration Properties'
In the right panel, select 'Debug' under the 'Configuration' column for your project
If you do not see the Solution listed in Solution Explorer, follow these steps:
In the menu bar, go to Tools -> Options
In the left panel, select 'Projects and Solutions' (you may need to check 'Show all settings' at the bottom-left area of the window
In the right panel, check 'Always show solution'
I hope this helps.
I too have all these. And I've done all this. It appears this happens to me every time I get a fresh copy of the entire solution out of source control. So if we've done all these, deleted dlls & .pdb files for all references (Assemblies) in the web project, used the clean option on the solution, deleted temp files, closed out VS and reopened, made sure debug mode is selected and set at full and optimations are off, what more is there?!?!?!
I had the same issue on my web project in Visual Studio 2010, and finally I found the reason why I was getting this message. What I did was to change an existing debugging option on Visual studio:
Go to Tools->Options->Debugging->Symbols->All modules
Check the "unless excluded" radio button
Click on the link "Specify excluded modules", then remove the DLL that you want to debug.
In my case it was my web dll file...
I had this when trying to remote debug an application on a computer that belongs to a different subnet. I was able to debug and step through the code when running it across the network if the machines were on the same subnet. After changing the subnet though I was unable to step through when running from the network and was getting the "The Following Module was built either with optimizations enabled or without debug information".
The solution? Easy. Copy the built solution across to the machine hosting the remote debugging and run it locally.
Had this happen to me on a VS 2010 winForms project. Seeing that the majority of people here have web projects, i think that it has to do with access to the folder in which the project is stored. I say this because when this problem occurred to me Google Drive was synchronizing the folder in which i keep my projects. It seems that just disabling the synchronization does not fix the problem.
My solution is similar to one of the answers above:
Went to "Project Properties > Compile > Advanced Compile Options"
Checked "Enable optimization"
Set "General debug info:" to "None"
Unchecked "Define DEBUG constant"
And pressed OK
Then went back and returned the options to their initial state.
Hope this helps someone as it seems this still happens.
Follow this : (first STOP debuging)
1:right click on project solution name or project -> Properties
2:under Configuration Properties select configuration Manager
3:Change configuration to debug and click on close
4:Change configuration to debug and click on Apply -> OK
Now rebuild solution....!
For me, Checking the "Optimize code" box in the project properties, saving, unchecking it, then resaving did it for me.
Disabling "Enable Just My Code" also worked, but that was more of a work-around than a fix as I didn't want that setting.
I have had same problem, but with different cause and solution.
The window was the same as that shown by Gustavo (above) but the path was in:
"\users\zzz\AppSettings..." (where zzz is windows username)
I had an Excel addin - I was testing the install of the addin, so I had a copy installed through VS install function. VS was obviously trying to debug both the installed copy and the copy I had just launched, and could not find debug symbols on the installed copy.
None of the above solutions worked (without side affects),
SOLUTION:
uninstalling the addin, and manually deleting the files in App Settings worked.
You mentioned it's a web project...do you have
<compilation debug="true />
in your web.config?
I had the same problem after building with a Release configuration.
It turned out that when I switched back to Debug, VS wasn't detecting any differences, so it was not updating the .dll and .pdb files in the bin folder.
Here's what worked for me:
Run iisreset (to clean up the temporary folders)
Save the web.config (to force VS to actually rebuild)
Rebuild on Debug
Start the project
Try a rebuild then debug.
My case is following: webservice referenced lib1.dll. Later I removed reference as it was no longer used. However lib1.dll remained in the bin folder.
Because library was not referenced then Rebuild and Clean actions were not helpful.
After manually deleting lib1.dll from bin folder I've get rid of this message.
If you are publishing to IIS and not using built in web server -or IIS express- make sure that your publish profile settings is in debug mode. In vs 11 by default it's in release mode.
Just to add, I was looking at this blog to find the solution to the same problem I was facing. Unfortunately the solutions mentioned above didn't help me. At last I figured out, I was installing my bits (along with .pdb) through installer and setting permission explicitly on the installation folder.
Because of which VS was not able to load the pdb even though the file browser was showing the correct file but it was giving the same error mentioned above.
Once I unchecked "Enable Just my code" and removed permission settings from the installer, VS started loading the module.
The one configuration that worked for me was the following
Project --> (Your Project) Properties --> Debug Tab
make sure Configuration is set to Active (Debug)
Under "Unable Debuggers", make sure "Enable unmanaged code debugging" is checked
I'm creating a Windows Service and here's what worked for me:
Uninstall the service.
Open a command prompt and go to c:\Windows\Microsoft.NET\Framework64\v4.0.30319
installutil C:\MyFantabulusWindowService\bin\Debug\MyFantabulusWindowService.exe
Greatness has been achieved!
Case : testing assembly with Console project in SharePoint development - if you're doing SharePoint development and seeing this alert in VS, make sure you deploy your SP assembly to the GAC before testing your console app IF your core SP project has methods you need to call in your console test app.
