I have recently been through the pain of converting an legacy WebSite project to a (C#)Web Application Project. During this time I also migrated the code from VSS control to Subversion on a dev server.
When debugging the application under VS2008 the project can literally take 4/5 minutes to completely load up. The majority of this time the Output Window states that it is loading symbols from Temp ASP.NET directory.
Figuring this may be an issue that it is under SVN control, I exported the project and began debugging without source control and this resolved the issue.
Can anyone suggest why this could be happening, ie. why under source control is it taking such a long time to debug?
Symbol loading shouldn't have anything to do with .svn. If moving your project solved the problem, I'd guess it's something to do with the difference between your actual copy and the exported one. Particularly, I'd say it would be to do with a file unlikely to be committed, like a ".user" file. The ".user" file probably has a lot of extra junk that VS is trying to load, and moving it means they got reset.
Check for any files missing (after a clean export...they'll have been re-created after you open the solution 1x) and you'll probably find the culprit.
You could try the TortoiseSVN client
The more plugins (Resharper etc) you have for VS the slower things tend to get.

I've installed the Visual Studio 2013 Preview to try out and I'm having some very bad performance issues. Every time I open a file and immediately try to close it, edit a file, save a file, etc. the IDE will stop responding for about 15 seconds.
I've gone through every performance tweak I could find through stackoverflow, blogs, web search, etc but none have worked (for example, clean up temp folders, disable add-ins and extensions, delete .suo file, etc.).
Using /safemode, the performance problems go away but I can't find what could be different since I have no add-ins, nuget packages, or extensions installed.
Using SysInternals Process Explorer, I can only see the process for devenv.exe peg the core it's using at 100% when it stops responding. I am not seeing any network or hard drive activity during this time and no other processes become active.
I've reinstalled with no luck, and I've installed it on another development machine where it seems to work just fine.
Anyone have any ideas?
Thanks!
UPDATE: In Process Explorer 'Other I/O Delta' shows ~200,000/sec when it locks up on the devenv.exe process. Still looking...
UPDATE 2: I guess I should add that this PC is a Dell Vostro 460, i7-2600 # 3.4Ghz, 8GB RAM, Windows 7, 1TB HDD with 550GB free, plenty of power for what I'm doing. Closed all other apps while debugging, including VIPRE A/V and Malwarebytes.
UPDATE 3: Maybe getting closer... using Process Monitor (love SysInternals stuff!) for some reason my entire C:\Projects\ folder is being parsed/searched by devenv.exe. I keep all my project folders under C:\Projects\ where there are about 20 projects each with their own sub-folder. Here's where it gets weird. In /safemode, devenv only parses the current project's folder, not the entire parent folder. Projects has 6,271 folders with 29,914 files. I tried creating a new c:\Projects2013\ folder, created a new test project, and devenv is trying to parse the full parent Projects2013 folder, yet in /safemode only parses Projects2013\Sample.
Obviously though the new project in Projects2013 runs full speed because it's parsing far fewer files. The other computer runs fine because I left the default Projects path and there were no other projects in that folder. Now what in the world could be doing this and why the different folder path between regular and safe mode? Time to dig through Tools, Options... ugh!
Here's a screen grab from ProcMon:
Final Update - Resolved! It was git causing the problem. I had a local repository set at c:\Projects\ which contained all my various project sub-folders. The dump file I created for them allowed them to narrow it down to git. Removing the local repository fixed my performance issue where VS 2013 is at least usable now. The programming team still needs to resolve the continuous re-parse of the folder though. Anyone with a very large repository will end up with this issue.

In the last year I've worked on two relatively large .NET projects and both of them have ended up with project/code generation strangeness that I just haven't figured out how to fix..
The first project generates some bad code for forms that causes the VB.Net build to fail. I actually had to make a search/replace macro that fixes the 5 problems by adding a Global. to the beginning of a few references.
I chalked that up to a random act of unkindness against me and went on my way since the macro takes about 2 seconds to run...
So now 6 months later and new project is cranking along and I get a similar-ish problem. I have a bunch of form controls that store state in a settings file using the built in capabilities of .Net. I had about 20 controls that were configured automatically this way. Works great until today when for reasons I don't understand in the designer.vb file gets corrupted. At least one other person on the planet has had this problem here:
http://social.msdn.microsoft.com/Forums/en-US/winformsdesigner/thread/9bd20b56-7264-4a1f-a379-ad66b372ddd3
but the proposed solution didn't change the behavior.
So now I've had two projects (larger ones) that have project file issues that I can't resolve (I've had several smaller projects that are just fine).
What tools are available to fix projects, migrate projects, lint projects ... anything to recover projects to a reasonable state? Any successful recovery procedures beyond a roll-back/merge?
i had a corrupted reference issue linked to my use of mercurial and VS getting lost in file save time... if this may help...
If you open it in notepad and its corrupted - then its probably corrupted and the only way to restore it would be to go to a backup.
--> go to backup
-->click your project name
-->and then find your fire thats are corrupt
On the current project I am working on, there is, at the moment, a large churn of code, which means updating from source control can mean at times many csproj file changes. As we all know, VS2010 doesn't have a "Reload all" button, but you must reload each project and confirm each reload.
Is there a method where either the project is auto-reloaded or the IDE can detect this and ask for a solution reload?
Finally found a solution:
http://lostechies.com/jimmybogard/2011/01/27/reloading-all-projects-with-vscommands/
Quoting from the site:
Quite often I’ll find myself working
in situations where multiple projects
have changed, and Visual Studio asks
to reload them, one at a time. This
happens when I’m working a lot with
source control, and doing things like
switching branches, performing merges,
or just integrating upstream changes.
I have to click “Reload” a million
times for each project that changed on
disk, and it’s quite annoying. On top
of that, VS forgets which files I have
open, so every file that I was working
on gets closed.
I may be the last VS user to find out
about this, but a free lite version of
the VSCommands plugin is available on
the Visual Studio Gallery that does
just what I need – reload all changed
projects at once, preserving which
files I had open:
It's a pain, but the best option I've found is to Close the solution before Getting the latest source code.
If there are more than two changed projects, it is faster to manually unload&reload the entire solution than it is to Get and wait for it to unload&reload the affected projects only - reloading projects is achingly slow (even disregarding having to click the OK button for every project that changed).
(In my mind the real question is: Why does it ask that question at all??? If you Get the latest source code, there is absolutely no sane reason why you would want to only use part of it. It's like a petrol station attendant saying "You've bought some fuel. Would you like me to now actually put it in your car, or shall I just pour it out on the ground?")
Well, that doesn't work if your references paths changed in the csproj file and your using something like the sysinternals junction tool to change a symlink. E.g. tool switches D:\Projects symlink from D:\Baselines\1.0\Prjects to D:\Baselines\2.0\Projects , and because someone changed the folder structure between 1.0 and 2.0, your .csproj file suddenly points the dll path from ....\References\some.dll to ....\References\3rd-Party\some.dll . I know that is a special case, but happens (e.g. in my company).
There is an alternative solution though, one which I highly recommend as it has other benefits, too: the not-so-well-known VS 2010 Extension Solution Load Manager. It defers loading of Projects to the background, or until manually loaded, improving solution load time a lot for large solution files. It has this "reload solution" button in it's menu (unfortunatlely there seems to be no shortcut) which then reloads all solutions from scratch, skipping/backgroundloading the solutions you set. A Microsoft guy commented on his blog that they wanted to include something similar into VS 2010, but the feature didn't quite make it.
Sure, it may take longer then "just" one click and updating 100 documents, but it solved my problem of (relative) reference path changes, and gives a nice speed boost every time I open an at least medium sized solution.
Edit as of Oct 2013
VS2012 includes this functionality by default. At least the async loading stuff. The "don't load at all" functionality is unfortunately only possible by using manual "unload project" in VS2012. But as pr-project memory consumption did go down with VS2012, it's not that big of a deal anymore.
If you have checked the option "detect when file is changed outside the environment" in the "Documents" section of options, projects and files are reloaded when changed. It works for me when switching branches in git.
This is driving me crazy and has resulted in lost work (not much, at least).
Normally, when I edit a file in Visual Studio, it's supposed to automatically check that file out in source safe. On multi-project solutions (e.g., web app with class libraries), sometimes none of the files in one project would automatically get checked out, though exiting & reloading visual studio may fix that problem temporarily. Furthermore, project files are never automatically checked out. Whenever I add/remove code files, I have to remember to explicitly check out the project file as well (otherwise we'll have issues with code files not showing up in the solution explorer, or trying to load non-existing files).
We're using VS-2008 and VSS 2005. Do you have any idea how I might fix this? There are no more visual-studio updates/fixes on Microsoft Update.
You need to ensure the files are read-only, or VS won't be able to tell that they are version controlled (or, at least that's what it uses to determine it). You can tell VSS to set itself up so getting the latest version places the files RW on disk.
There may be other problems here, but that's what comes to mind first. My advice (that I took myself) is to migrate to SVN or an alternative. Losing work is unacceptable.
I have a VS2005 solution which contains a variety of projects (C++ DLLs, C++ static libraries, C# assemblies, C++ windows executables) that are combined in various ways to produce several executables. For some reason, every time I open the solution, VS2005 wants to check out one of the projects for editing. The project is not modified in any way, it's just checked out. If I configure VS2005 to prompt before checking out, I can cancel the auto-checkout during load with no ill effect that I can see. It may or may not be relevant, but the project it keeps checking out is cppunit version 1.12.0 (the static lib version). How can I stop this annoying behavior?
Other potentially relevant (or not) details:
Source control is Team Foundation Server (not Visual SourceSafe)
no .suo or .ncb files are checked in
the .vcproj and .vspscc files are being checked out
When I close the solution or shut down Visual Studio, I'm asked whether I want to save changes to the project. Answering yes results in no changes to the file (Kdiff3 compares my local file to the server version and reports"files are binary equal")
Attempting to check in the "modified" files results in a Visual Studio message saying "No Changes to Check In. All of the changes were either unmodified files or locks. The changes have been undone by the server"
As Charles and Graeme have hinted at, Visual Studio constantly make changes to user option files and such on the backed even if you don't make changes to the project directly.
I'm not sure what information is being stored but I do know that it happens. Common remedies is to not include the *.suo files. I also don't stored anything in the bin or obj folders in sauce control as this can have a similar effect as your talking about (if you build). (Checks out the project upon a build. Thought this does take an action to happen).
Overall it is unavoidable. It is just how VS2005, 2008 work.
Does this answer your question?

Frank
There are two reasons I've encountered that cause this behavior.
The first is old source control bindings. If you have a project that used to be managed by another source control tool, it might have leftover bindings in the project file. Open the project file, and change the following settings from something like this:
SccProjectName="$/Team/Platform/Projects/MyProject"
SccAuxPath="http://teamFoundationServer.example.com:8080"
SccLocalPath="."
SccProvider="{88888888-4444-4444-4444-BBBBBBBBBBBB}"
to this:
SccProjectName="SAK"
SccAuxPath="SAK"
SccLocalPath="SAK"
SccProvider="SAK"
Different project types are defined in different ways. The above example is from a .vcproj, C# projects are in XML, VB looks like something else, but the meanings are the same. Simply set all four values to the constant string "SAK" and Visual Studio will automatically handle source control. See Alin Constantin's blog for details.
I haven't yet discovered the root of the other reason, but the project that is giving me trouble is also CppUnit 1.12.0! I'll keep digging and post my findings.

Have you put a .suo or .ncb file into source control perhaps?
Have you tried closing VS2005 after it checks out cppunit and then seeing if any changes were made?
I often encountered something like this with Web App solutions where the project file wasn't actually saved until you closed studio down and reopened it.
Just to clarify, I'm assuming that you mean Visual SourceSafe2005 is causing the problem, not Visual Studio. (FYI, Visual SourceSafe is usually abbreviated VSS.)
I've experienced this issue with VSS before. I think the limitation is really fundamental to Visual SourceSafe: it's just not that good of a product and I would move to something else if it's a decision you can influence.
If you can move to something else, I recommend Subversion for a small or medium-sized project. It's free, and does not use the pessimistic locking mechanism that Visual SourceSafe uses by default. There's an excellent Visual Studio add-on called VisualSVN that will give you the same functionality in the IDE (seeing what files have changed, etc.) that you get out of the box with VSS.
If you cannot change source control systems, I believe Visual SourceSafe has a mode called "non-exclusive checkouts" or something like that that uses the optimistic locking that Subversion and other source control systems use. Try setting that option at least for the files that are obviously not being changed and see if that resolves the issue.
I get this a lot when one of the projects in the the solution has source control information with path information that is not the same in source control as on your workstation. When VS opens the project it will automatically attempt to check out the project in question and
To fix it, you're best off having everyone who uses the project remove their local copies and do "get latest version..." to grab what is in your source control database.
you can also check the .sln file and look in the GlobalScxtion(SourceCodeControl) area for each project's information and see if the relative path is not how you have the projects stored on your workstation - though manually changing this file vs. doing a "Get Latest Version..." is much more likely to cause problems for the other developers who use the solution as well.
Your cppunit project is probably automatically creating one or more additional files when the project first loads, and then adding those files to the project. Or else one of the project's properties is being changed or incremented on load.
If you go ahead and check the project in, does it check itself out again next time you load it? Or does checking it in fix the problem for awhile?
Very often this sort of behavior is caused by VS trying to update source control bindings.
Graeme is correct, VS will not save project or solution files until you close VS.
I would let VS check the files out, then close VS, then diff them.
