Visual Studio 2012 - corrupted .cs file - c#

Few hours ago I started a new project. I pretty much finished it up, but I was making some performance tests with it. During those tests my PC suddenly crashed, so I needed to restart it.
After reboot, when I open my project, my main .cs file doesn't want to open! When I click on it in visual studio, it opens a blank notepad file! How do I retrieve my code from that file? Almost all of my code was in it...

Seems like it is not a VS related question but file recovery based one.
If you ever saved your file, chances are that you can recover them. Winhex is a good tool to recover deleted files. Here is how.
If you never saved, chances are very bleak.

I have same problem few days ago. My PC restart suddenly and all file that is opened in VS is no longer work.
Try to open this file in Sublime text and Notepad++. If this will open file then you can copy it otherwise their is no way to read that stream that is look like $$%%$%%$#^%#^$
What I do is coding back from backup copy and spent my few more hour to recover my work by doing it again.
I believe if your code is personal then you should backup it or try private git (bitbucket,github) somewhere so you can easily get your thing back instead of 100% total lose of data.

Why is my asp pages executing cached code

I've got an application I'm taking over with a very strange issue.
The background: 60+ identical IIS applications running on windows server 2012 that I rdp into.
Each application is identical except for some image files and the web.config files. (yeah, I know)
The applications are not compiled but just run as cs files. No proj files or sln files either.
There is one compiled app, which runs as a scheduled task, and uses some of the files in each of the application folders.
The code is C# and I'm editing it with notepad++.
The issue:
I've been trying to update some of the code in one of the test applications but my changes don't seem to be taking effect. (specifically update a log file and send emails). The current emails work but my new one does not appear, nor do my log files show up.
I tried to test it in another test application just to see if it failed there too, and found that that website came up with an error in some code on a specific line of a specific file.
Thing is, this line of code is not on the same line in the actual cs file.
I then added another line higher up to see if I could get a divide by zero error.
Same result. Same line of code failed with the same line number. No change at all.
Seems like my code is being cached and I can't refresh it.
I tried making sure it's not being cached by the only scheduled task and cycling IIS entirely (at the root).
Still happening.
I know for a fact that it's not a matter of an exe hiding somewhere as two weeks ago I made a change to the code and it worked. My change showed up. I also know for a fact that I am editing the correct file. I opened the folder using Explore in IIS.
There are no obj folders. There is a bin folder in each application folder but nothing in the bin folder except nuget package dlls.
Ok. So after I spent a week trying to set each app's web.config to use tempDirectory=a new temp directory based on the app name, I finally discovered that the previous coders had made two copies of the relevant file. Identical copies. One for use by a scheduled task and one for use by the website itself.
So all the time I was trying to detect changes in the result of my code, I was changing the one the scheduled task used.
Of course, in the several times I discussed the problem with the previous developer (who was still working with us), he never bothered suggesting the solution, although he's been working with this code for several yeas.
Updating the correct copy solved the problem. I've also discovered my head hair was shedding faster in the last few weeks than ever before.

Constantly get The local data store is currently in use by another operation when working on small projects

I use Visual Studio Team Services to store the source code of my projects as I work on them, I love the service, especially that it is free, but I have been running into the biggest pain lately.
Randomly when I go to save, modify, check in check out I get this error for every single file I am modifying. So if I am trying to save changes to 8 files I get this message 8 times and it takes 45 60 seconds of trying to check out for each file meaning to takes 6 - 8 minutes for the errors to stop (even if I hit cancel).
The local data store is currently in use by another operation
I looked it up online and found many people with the same issue but the response from MS has nothing to do with my situation.
http://blogs.msdn.com/b/phkelley/archive/2013/05/31/tf400030-the-local-data-store-is-currently-in-use-by-another-operation.aspx
It basically says this can happen when you have to many files in your workspace or have several large solution open at once.
This does not apply to me as I usually only have on solution open at a time and my projects are very small (400 -500 files).
Ran into this issue as well on VS 2013 and TFS - every time I opened my team explorer it would take 10+ seconds to show all projects, then when I would expand the project in source control, another 10+ seconds would roll by.
Earlier today I began to experience the "local storage is being used" error when trying to save data in class files. I did some original research, and this following link saved the day for sure. Now TFS is blazing!
Local Data Store Solved
What you do is edit workspace (including all projects associated), and change the "Location" dropdown from "Local" to "Server". It took about 4-5 minutes for the changes to finish, but well worth it.
Hopefully this will help someone down the road.
Lately I started to get same error message and Visual Studio started to work very slow with TFS and nuget. I have tried repair and uninstall but not solve the problem. At the and it was so painfully slow that I cannot continue working. (Expanding one item on source control explorer takes 10 seconds)
Here is my story and how my problem be solved:
I was mapped tfs folders separately not to get whole TFS because there are lots of irrelevant documents. After trying lots of fix suggestion, I thought this might be the problem because I did this separate mapping first time while I have been using TFS. I generally map and get all items at once and never met this issue before.
I removed all mappings and it was like magic. Error is gone, slow TFS source control is gone and it is rocket fast now. Just to be in a safe side I also delete my workspaces and create a new one and get all TFS items at once.
I found the error would be triggered when I had more than once instance of VS 2012+ running utilizing Source Control Explorer, Solution Explorer and/or Team Explorer windows. I've not had this problem when running a single instance of VS 2012+ (on updates 2+) utilizing Source Control Explorer, Solution Explorer and/or Team Explorer windows in tandem.
I found this article and gave it's suggestion a shot: to prevent multiple threads from accessing the data store simultaneously.
http://blogs.msdn.com/b/phkelley/archive/2013/05/31/tf400030-the-local-data-store-is-currently-in-use-by-another-operation.aspx
This proved to be a remedy for this issue.
I would add for other users with large file repositories, using source control and share this issue, it may be greatly beneficial to create multiple workspaces for each of your branches/repositories. I found that by doing this my queries to TFS sped up immensely and also helped with this error. I found this suggestion here: http://blogs.msdn.com/b/phkelley/archive/2013/05/30/using-multiple-workspaces-with-visual-studio.aspx. I share this as users mention TFS running slowly.
I also started getting the same error this week. Maybe there's something wrong with VS Update 3?
Simply could not work on any of the projects of the "broken" local workspace anymore.
VS would show all files as being checked out, but none were really.
Other local workspaces were working fine.
I tried removing a project from the workspace, but when trying to confirm it, I would receive the same TF400030 error again.
Suggestion
If nothing else works, you might want to try this: simply delete the whole workspace and create it again, this time separating projects into different workspaces. This worked for me.
You'll probably want to back up your files first.
I did as mentioned below and TFS started working fine
Close all the VS instances
Go to: C:\Users[UserName]\AppData\Local\Microsoft\VisualStudio\15.0_46af8b8e
Delete the privateregistry.bin file
Reopen the project solution
Above worked for me.
Had the same problem,can be fixed in 3 quick steps:
Remove current Workspace: Source Control Explorer->Work Space ListBox->workspaces... and remove the workspace.
- Make sure that all pending changes are checked in
Delete Workspace local folder.
- Its Better to delete the folder entirely.If eventually keeping some folders make sure to delete all $tf folders (hidden folders inside the workspace folder)
Remap the projects you need ( the less the better )
Hopes that helps.
In my case the cause was a compressed folder containing my local data store, shown in blue in Windows explorer. Removing the compression did the trick.
I ran into this error when renaming my workspace. After changing back to original everything worked fine again
Restarting the Visual studio resolved the issue for me.

C# Cannot write to Application.ExecutablePath, some boxes i can some i cannot? uninstall from this

So I have been writing to
Environment.SpecialFolder.ApplicationData
this data file, that upon uninstall needs to be deleted. I am using Innos Setup to build my installer. It works great for me. So my data file hangs out in the above path and I do that cause when I used to try to write it to
Application.ExecutablePath
certain boxes I tested it on would throw a nasty error at me trying to write data there. I do research and somehow its not always writable and its how i came up with the Environment.SpecialFolder.ApplicationData
That is why my data file now resides in the SpecialFolder.ApplicationData. Trouble is if the user uninstalls and reinstalls I need that file gone. It might be a short coming of my knowledge of Innos but I cannot figure out how to know where that file will be to tell innos that.
So then I thought I had a clever solution: Innos can run a file when its done uninstalling, so I had my program create this file "uninstallData.bat" that says:
del "the file in my special folder application data path"
and I wrote it out to drumroll
Application.ExecutablePath
(yes it was a while in development and I had forgot it was't doable.)
So of course I am back to square one, I need to write a file to a path Innos knows about {app} and I need it to be able to delete my data file in the SpecialFolder... i don't care how I do it i just need that file gone.
Are there other Environment. or Application. approches I have missed? Maybe somewhere that is viewable by an uninstaller AND can be written to?
As an aside, I am not sure why my box I develop on can write to the application folder no issue, but it cannot on other boxes... weird.
Any input would be great sorta lost as to how to crack this nut.
The environment location is in the user profile. If there are multiple users on the machine, and they all run the application then a copy of the file will be in each profile.
The path also depends on the OS.
Regardless, the current user's app data location is pointed to by %APPDATA% and %LOCALAPPDATA%. These Windows environment variables should be available within Innos.
Appliccation.ExecutablePath is not writable per standard defintions - the program files folder should never be manipulated by running applications. Ther area number of special folders for that. Nice that you finally found.... what is properly documented by Microsoft for a LONG time now (minimum 10 years).
I suggest you get a proper installer - WIX comes to my mind. Your problem is totally unrelated to C# - it seems to be totally a "crappy installer" issue. Or provide a PROGRAM (not bat file) to run at uninstall. What exatly is your problem there?

SOS: file recover

Hallo all,
I made some revisions on a c sharp file in visual studio 2008 express, and committed the following actions:
1. open this c sharp file thru notepad,
2. tried to save some modifications in this file while it was opened by the notepad,
3. Ctrl+C and Ctrl+V to make a copy to this file
4. closed visual studio 2008 and notepad
Then this c sharp file dissappears! Please help!
John
It's gone forever. The only thing you can really hope for is to pair the situation with the appropriate whiskey.
If it was months of work down the drain, I would choose Ancient Age out of the plastic bottle.
if you right click in your project and then goto add existing you should be able to re-add it.
As to why it disapears i am not sure ... i guess it may be a file handle problem.
Is there a repository, a version control system, or something like that? Otherwise, let your code RIP.
Sounds like it has probably gone forever, but you should be able to recover it from your daily backups. You do take daily backups don't you....?

How to disable Visual C# activity from appearing in My Recent Documents?

I would like activity in my Visual C# 2008 Express to not appear in My Recent Documents (I use Windows XP). To clarify, when you open a solution or other file in Visual C#, a link to that solution or other file is added to "My Recent Documents". I would like that not to happen.
How can that be achieved?
I know there's a chance this question is better fit for one of SO's sister sites, but my best judgment was that it fits here...
Thanks
I know there is a away of stopping Windows from updating the list, but I don't believe there is a way to stop it from updating for certain file types.
I way you may be able to do it with is to use batch scripting.
cd "C:\Documents and Settings\PROFILE_NAME\Recent"
del *.<C# file extension or other project extensions>
...
del *.<C# file extension or other project extensions>
Create the file using Notepad and save it as <any name>.bat.
After you work with you C# project you just run this Batch script and it will remove all your evidence from your My Recent Documents folder.
NOTE: If you can't access the Recent folder (because it's hidden) try replacing Recent with My Recent Documents
Thanks
link textI've added this functionality to Visual Studio MRU editor.
The list of extensions is currently fixed, and it needs to be roughened out.
The new prelimenary executable can be downloaded here.
... and the Sources, in case you don't trust me ;)
(I'm not sure if I should keep the separate "save" handling - it was a good idea during testing, but otherwise is rather annoying).
