When trying to debug my Blazor wasm app in Visual Studio Community 2022, after I hit a breakpoint and check what I want to check and then Step Out, the app starts to stop several times with the following message:
Frame not in module
The current stack frame was not found in a loaded module. Source cannot be shown for this location.
It seems like it's trying to step into the wasm files by looking at the locals when these stops happens:
I still can Step Out and continue but have to do it several times which is time consuming.
I have tried enabling "show disassembly if source is not available" to no avail. I also have tried deleting the obj and .vs folders and restarting VS.

I am currently trying to debug an ascx.vb page and the breakpoint is not hitting the page.
I am getting this error "The breakpoint will not currently be hit. No symbols have been loaded for this document".
I have been using this project for 2 months and never encountered this error before. I just did a small change on add button save it on chrome could see the change however, when i am debugging getting this issue for the first time.
Steps done:
Attach the breakpoint to the ascx.vb page
click on debug then attach to process as below (highlighted in yellow) :
checks already done:
Project is being run on debug mode
when debugging the symbols are not loaded.. have check Debug windows modules and is as below:
I have tried loading some symbols which created a folder symbolscache but still the debug point did not hit the page.
Is there something wrong in browser/iis or VS.
I was using VS 2017 but the same issue is occurring on VS 2019 professional.
Any help will be highly appreciated.
Thanks.
You can try to disable the "Just My Code" option in the Debug/General settings.
or
Right click the Solution in solution explorer, click "clean solution", this deletes all the compiled and temporary files associated with a solution. do a rebuild of the solution and try to debug again.
I have inherited an ExtJS project that uses ASP.NET Web Handlers (ashx files) to access a database.
I'm trying to debug the connection to the database which is in the C# portion of the code.
I've tried adding a break point just before the connection to my database is made, but I can't seem to get the application to stop there. They only briefly turn white during debug-execution. Hovering the mouse over the breakpoint when it's in that state shows:
The breakpoint will not currently be hit. No symbols have been loaded for this document.
I've been all over this question, with no better results
In the modules window, the Symbol Status of the DLL does indeed show Symbols Loaded.
The dll/pdb both seem to be copied over to C:\Users\myid\AppData\LocalTempTemporary ASP.Net Files\etc.
(this seems odd, because I would expect it to attach to the .dll in my work folder) Is there a way to tell the debugger to look there instead?
There of course is no exe since this is a web app.
I've:
tried cleaning the solution and rebuilding fresh including a fresh pull from the repository.
verified the build has the "Define Debug Constant" and "Define Trace Constant" are checked
deleted the contents of Temporary ASP.NET
checked the the project was set as Debug
checked that "Just My Code" was disabled in Debug / General
restarted the workstation completely
checked that the Solution has the right project starting (there's only one in it)
checked I'm building in debug (not release)
made small changes to the code to force a recompile
checked that "Automatically determine the type of code to debug " is selected in Attach to Process
run as administrator
checked Optimize Code is not turned on in the project properties
checked that "Use Managed Compatibility Mode" is turned off
There is no aspx involved so the CodeBehind/CodeFile issue is moot.
Beyond that, that answers are very much repetitive or I tried something at random and it worked.
What have I missed? Is there something basic that you are supposed to do with the project so it will let you debug the DLL that perhaps the original developer didn't do (no they aren't available to me)?
Problem resolved...
Ultimately there were two issues.
Originally, the DLL had been compiled as 32bit DLL which didn't play nice with the database (Oracle 64bit). Switching the platform target should have resolved the issue except, IE's cache of the web page hid the fact that I was now getting a classic "Could not load file or assembly xxx or one of its dependencies." error. [incidentally, I've now sett he cache to clear on exit]
This error was caused by IIS Express running in the 32 bit version instead of the 64 bit version. Which means the DLL never really run, and explains the "No symbols have been loaded for this document." warning.
That was then resolved by going to Tools -> Options -> Projects and Solutions -> Web Projects and turning on Make sure that Use the 64 bit version of IIS Express for web sites and projects.
Clean and rebuild, and everything works tickety-boo
My solution contains many project and I am debugging that. Few days back it was working fine but now when I debug it is moving randomly, means when I press F10 it is not going to next line but any random line.
I am not using multithreading.
I tried cleaning solution.
Tried re-starting VS.
Tried re-starting computer.
Ensured application is not running optimized code.
Tried checking/Unchecking "skip over property/operator" checkbox under Tools > Debugging.
Confirm current project (one being debugged using Configuration: Active(Debug) and Platform: Active(Any CPU))
Ensured only one instance of application is running.
Now what could be the reason?
I am getting strange and annoying behavior in one (yes, only one) of my RStudio projects. Whenever I restart the R session within this project, I can no longer save any of the files, and when I try to (or RStudio tries to automatically) I get a popup error saying "The system cannot find the file specified" and I have to reopen the project and all of the R scripts.
I looked at the log file, and I see a lot of the following error:
07 Oct 2015 00:52:05 [rsession-Mark] ERROR system error 5 (Access is denied) [path=C:/Users/Mark/GoogleDrive/Research/CEQUAL_event/.Rproj.user/5E5F98D9/sdb/s-26E44539/lock_file];
OCCURRED AT: bool rstudio::core::FilePath::exists() const C:\Users\Administrator\rstudio\src\cpp\core\FilePath.cpp:308;
LOGGED FROM: bool rstudio::core::FilePath::exists() const C:\Users\Administrator\rstudio\src\cpp\core\FilePath.cpp:308
It looks like the problem may be in the .Rproj.user folder. So I deleted that and let RStudio regenerate it, but the behavior started right back up again.
I am using Windows 7, RStudio version 0.99.441, and R version 3.2.2.
I think #Jack Wasey is right: Google drive locks files during sync. This causes many issues with other programs as well. There are alternatives from companies that do file syncing for a living, such as dropbox, whose clients don't lock files. With google drive you only have the option to use selective sync and exclude every .Rproj.user folder. Once the RStudio's database is corrupted, moving the project out of the Google drive folder won't be enough - you will need to delete/rename it to have RStudio fix its database.
Summary:
Copy contents from all unsaved files to a temp file outside of RStudio (while clicking away the error message every other second)
Quit Rstudio
Pause Google drive syncing
Rename (or move/delete) the hidden .Rproj.user folder in your project
Reopen the project in Rstudio
Exclude the new .Rproj.user folder from syncing with Google drive (Preferences -> sync only these folders)
Remember that Google drive is free / Become an awesome google developer and fix the issue once and for all
May not be related but might be helpful to someone else. I was getting the same error (over and over) and finally realized that I had an R session open from days ago, that had eventually gotten stuck. It was running in the background with a "Fatal Error" message waiting for me to click OK. When I closed that session everything started working again.
This was happening to me as well, but curiously only when I was using Project files (.Rproj - not stand alone R scripts). It was driving me crazy.
I found that buried in the settings (Tools -> Global Options -> Git/SVN) there was a setting "Enable Version Control Interface for RStudio Projects). I guess I had turned that option on when I was messing with my settings and then forgot about it since I don't normally use project files.
What worked for me was I noticed DescTools package I installed caused it, though it served the purpose I installed it - fetched me mode value without going through mode functions. I then deleted the line I got the install.package, re-saved the project (ctrl S) and I could knit it.
Bottom line, read the error message soon as the box pops up, it's going to give you a hint of what line is causing the issue.
I hope this works. Enjoy
I am running Visual Studio Ultimate on Windows 7. Here is the description of my problem:
My VS 2010 had been running absolutely fine until today when it started giving error "External Component has thrown an exception" when I try to open a new website. Creating a new web application works fine though but I am unable to run any of them.
While trying to run the previously created websites/webapps, its giving error as "Unable to launch ASP.NET development server".
And when I try to debug the website/web app, I am getting error: "Unable to launch ASP.NET development server. An attempt was made to perform an initialization operation when initialization has already been completed".
Similar errors are coming when I try to open Windows Form Applications and other projects.
No errors are getting logged on event viewer and I cannot see any other error information apart from what is mentioned above.
I searched all over internet but no help. I have already trying un-installing VS2010 using the script at this link (provided by MS). But when I re-install VS2010, it still shows me same error. To my surprise, after re-installing VS still shows the previous project list in "Recent Projects". I really doubt if VS is getting uninstalled.
I am totally clueless and any help would be highly appreciated. I am left with no other option but to format my OS if I don't find a solution here :( Please do let me know if any other details are required...
It might be caused by an adding or extension that you've installed, maybe without being aware of.
there are several ways to deal with that - one is to get inside add in manager and remove/ deactivate them.
if VS can't load there is a flag that should do the trick.
check this link for instructions on devenv flags.
you can use: /ResetAddin or /SafeMode
