I've got a simple console project where I'm reading two Excel-files. The Excel-files are included in the project ("add existing item") and I've marked them with "Copy to Output Directory". However, they are not copied to the debug-directory when debugging/running the code.
I feel like I've forgotten something trivial. What do I need to do more?
In the file properties in Visual Studio, set:
Build action: None
Copy to output directory: Copy always
Changes to non-source code files don't cause a rebuild to occur - they aren't considered when the compiler does it's out of date checking.
Try forcing a complete rebuild by deleting your output directory completely (sometimes doing this from within Visual Studio isn't complete).
It may be that the files haven't been copied across because a full build hasn't been run.
None of this worked for my WPF project. You need to mark it Content + Copy Always.
Refer to this page for details on the different Visual Studio file properties.
Did you mark them as content?
I had an issue when some png files was renamed-excluded-added again to project. It seemed that VS2015 had lost tracking what to do with these files: although in VS the "Copy to output directory: Copy always" was set at the problematic files, CopyToOutputDirectory key was not present in csproj file. I had to change csproj manually from
<Content Include="xxx.png"/>
to this:
<Content Include="xxx.png">
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Content>
Silly question but are you running in debug mode? I've made the same mistake and realised I was in release mode.
I put Content and Copy Always and it worked.
I just had this problem and for some reason choosing "Create application without a manifest" under the project's properties finally copied the linked content file to the build directory.
VS 2015 behaves similarly, not updating the output directory correctly with Content files. What does seem to work, strangely, is to put a text file in the folder with the Content files and make it a Content file also. The text file will get copied to the directory and so will all the other Content files. Stranger still, if you then delete the text file, it will continue to show up in the output directory even though there is no longer an original to be copied.

In VisualStudio2010 I changed the name of the project and the name of the solution.
When I try to open the solution I get this error:
One or more projects in the solution were not loaded correctly.
Any idea why I get this error?And how to fix it?
Try opening the .csproj file in notepad and making sure all references and paths are correct.
In my situation, I had the GlobalSection duplicated in my solution.
I'm using TFS and sometimes it has trouble to merge configuration from multiple developers at the same time.
Open your Solution (.sln) in NotePad++ and look up for this tag and remove one from the duplicated.
GlobalSection(TeamFoundationVersionControl) = preSolution
You may need to readd the last projects to the solution though.
I got the same trouble when using VC2012. My steps for it are: Control Panel --> Program & Functions --> Right Click on VC2012 --> Select "Recover" --> restart Windows --> re-open the project. It works.
The trouble comes from the damage of VC2012 iteself.
Try to open the application as a website instead of project. In my case the project/application was created as website and when i was trying to open the solution it was giving me the error so i opened the application as a website and the application got loaded.
Check .sln and .csproj files to see if any unused references are added without knowledge
I got the same issue after the code merge. The issue was few closing XML tags were removed. Fix: Open the .csproj file in a notepad and correct the closing tags.
I had this problem, the path for the .csprog files in the solution some how changed, instead of \\server\folder it changed to \server\folder.
Try open the .sln file using the Notepad and check all the .csproj files path.
I've run into a problem with VS2010 (it also exists in the latest version, SP1 (10.0.40219.1)):
Add an existing Word file to the "Solution Items" and check this new file in.
Check the file out for editing
Double click on the file and edit it in Word (just make some minor changes)
Save the file (CTRL-S)
Now the file is removed from the "Solution Items" in Visual Studio (you may have to repeat the editing and saving a couple of times)
Update: I'm using Visual SourceSafe 2005.
Despite my research efforts I haven't really found anything on this issue apart from this Microsoft page, and I'd like to know whether there is a way to prevent this problem from happening.
Any ideas are more than welcome, thanks in advance.

After further investigation I think I found the reason behind this behaviour and a workaround.
Please also note that the behaviour described in the original question only occurs for files that are added directly underneath a solution or to a folder that is directly underneath a solution.
The reason
I'm not sure whether the following is 100% correct, but the main point is how Word (and probably other MS Office apps as well) saves an existing file:
Save the current version of the file to a temporary file
Rename the original file so it can be used later in case something goes wrong
Copy the temporary file to the location of the original file, using the original file's name
Delete the original file (that was renamed in step 2)
Visual Studio picks up that the file doesn't exist (for a very short time though) and removes it from its tree and the .sln file. This can also be reproduced by manually adding any kind of file, checking it out (if not checked out), renaming it to a different name and then back to its original name => file is no longer shown in Visual Studio.
The workaround
I've created an empty project template following the steps on Microsoft's site. I also set the output to "Class Library" so that the project would compile even if no static main method exists. This template can be used to add a "Documentation" project to an existing solution. Underneath this project you can add files and edit them as you wish, as Visual Studio behaves differently and does not remove the file when it is saved in this constellation.
Obviously this approach is still not very satisfying or elegant, but I hope that it may be helpful for others who might run into the same problem.

I've run into the same issue. I simply undo changes for the solution after I've closed the document file and the solution files will be as they originally were before your document changes.
I get this error when I try to load a VS 2008 project from TFS source control:
The project file has been moved, renamed or is not on your computer
After I click OK the project says "unavailable".
What is the problem? How do I resolve this? I never had this problem before. Some blogs said to delete the .suo file but I can't locate the .suo file. I deleted the entire project on my local computer so that the next time it opens it will create a new one, but I still get same error.
What typically helps to fix it is deleting the Solution User Options aka "SUO".
VS up to 2013
In the older VS it is stored as a "hidden" SolutionName.suo in the same folder as the main .sln file.
VS2015 or later
In VS2015 the same data was moved to a "hidden" .vs folder under the same folder as the main .sln file.
I just ran into this issue using VS 2013 after renaming a project. Stanley's answer guided me to the solution:
Close VS - delete .suo file - start VS again.
Delete the .suo file in a special way.
Don't have the solution open when you delete the hidden .suo file.
Restart VisualStudio.
Open solution and Add project without error message.
TFS works like most source control packages: It remembers what it has put on your computer so that when you "Get Latest" it only has to get the chnages since your last "Get" instead of having to get absolutely everything.
This has one caveat: If you delete or rename the local files on your disk, TFS won't know that you have done this, and it will still think they are where it left them.
If you then "Get Latest" it will not bother to update the missing files.
You are then likely to get all kinds of "missing file" errors, from TFS and any other tools that look for the files.
To get around it, you need to:
If you think you might have any changes in there that you don't want to lose, copy the source folder on your PC as a back up just in case!
Right click on the project (in Solution Explorer) or folder (in Source Control)
Choose "Get Specific Version" from the context menu
Choose to get the "Latest Version" and tick the option that says (something like) "force get of files already in your workspace", which tells TFS to forget about what it "knows" and get all the files again anyway.
If you have any locally-changed (writable) files, then be careful. There is a second option that will overwrite these, losing your changes. But you have the backup, so you should be safe. It's generally better to tick this option as well to make sure that all your source code is completely up to date. (But obviously only if you don't mind losing any local changes!)
When you OK, this will forcibly get all the files in the project to your local drive, and should correct the problem.
Easiest option worked out for me is:
Right click the project & Remove the "not loaded" or "unavailable" project
Right click the solution & Add "Existing Project"
Though it's well known VS defect, definately we can handle it!
Open the solution file in edit mode
Modify the relative path to match the modified/moved physical path ..
SccProjectUniqueName1 = Source\\Order\\Order.csproj
SccProjectName1 = Order.ApplicationService
SccLocalPath1 = Order.ApplicationService
Also, makesure of correct relative path for the referring project(s)
Project("{asdasd-301F-11D3-BF4B-asdasd}") = "Order",
"Source\Order\Order.csproj", "{E25641BC-C990-40E2-8876-08AE8728F763}"
EndProject
Try opening the .csproj or .vbproj instead of the .sln. What has probably happened is the .sln (solution) file has a absolute file reference (instead of a relative path) to the compoenent project(s). You may need to re-create the .sln, or hand-edit it.
In my case, deleting the .suo file was insufficient. I discovered that my workspace configuration had an error. I discovered and resolved the problem with these steps:
In Team Explorer, "Manage Workspaces..."
Click "Edit..."
Correct the value under "Local Folder"
Finally, delete the affected .suo files per the accepted answer.
I found it easiest to create a new Solution sln file.
Clear out your workspace mappings (File -> Source Control -> Workspaces). Edit the workspace and either clear out all the mappings (more repercussion) or find the one that's associated to this server path. Then open Source Control Explorer and remap. Double click the SLN in Source Control explorer and it should get latest. Not entirely sure what has happened or what state you managed to get into, but with this should get you moving again.
I ran into this issue and was able to resolve it by obtaining the .rptproj files from a co-worker and copying them into my local directory. The project was then able to re-load.
I spent a lot of time for trying solve this problem. I did these steps : rename project, rename namespaces, rename project folder, edit .sln file, edit hidden .suo file. Project loaded but it was unrecognizable for TFS! Finally I found this guide.
If you're using Resharper and TFVC is your version control, follow these steps :
Right-click the project in Solution Explorer, select Rename, and enter the new name
Right-click the project again and select Properties. Change the "Assembly name" and "Default namespace" on the Application tab.
Right-click the project again and select Refactor -> Adjust Namespaces. Accept the changes.
Change the AssemblyTitle and AssemblyProduct in Properties/AssemblyInfo.cs
Delete bin and obj directories in Windows Explorer
Open the Source Control Explorer and rename the project's directory. This will close the solution. Let it be closed.
Open the SLN file (with a text editor such as Notepad++) and change the path to the project (there should be multiple places).
Open the Solution again. Clean and Rebuild the project.
Right click on the unavailable project and edit the project file ... chances are, you will find a hardcoded file path or a virtual one that does not match where you checked the project out to.

Solution for this
Again rename the project folder
Set specific version & force get in TFS
remove read only & hidden option in the latest folder (not the rename one)
Now you can open the project without any issues
Sometimes, even though you changed .sln and .csproj path, and manually rename, you might forget to check the folder name that contains the project.
It happened to me too. Apparently the csproj files were not checked in when I had created them in my old computer, and so when I downloaded the project from TFS in my new computer, the files were not there.
After checking them in using my old computer and getting them from TFS in the new computer, I succeeded in reloading the project.
In my case, because I modified .csproj file, it changed to .csproj.user .
I remove .user from the end of the file.
Occasionally (usually after having updated my .sln file in source control) I get a strange Visual Studio error wherein I'm unable to open some of my files. The files in question show up in the appropriate project, but trying to open them results in an error dialog saying "A file of that name is already open."
This is virtually identical to Why does it say "Project with that name already opened in the solution"?, except for files, not projects. The solution given there was does not fix this.
Visual Studio internally maintains a list of currently opened files, to avoid problems caused by opening files more than once. Any number of things (crashes, reboots, updating files in source control outside of VS) can cause this list to become corrupted.
In any case, the problem can be fixed by deleting the hidden Solution.suo file which is in the same directory as your Solution.sln file. This will cause you to lose your current workspace state (open files, window layout, etc.), but it won't have any other adverse affects on your solution.
This is a hidden file, so to see or delete it you either have to enable viewing hidden files in Explorer or use del /AH Solution.suo on the command-line.
Delete the hidden .suo file and edit the .csproj file to remove the lines below:
<SccProjectName>Svn</SccProjectName>
<SccLocalPath>Svn</SccLocalPath>
<SccAuxPath>Svn</SccAuxPath>
<SccProvider>SubversionScc</SccProvider>
Now, reopen the solution to solve the issue.
Do you have any linked files in the solution?
Visual Studio has an invariant that only a single file of a given path can be open at one time. This invariant is hit most often when you have a linked file in your project / solution and attempt to open both the original and one of it's linked references.
Open csproj file of the project and delete following lines:
<SccProjectName>SAK</SccProjectName>
<SccLocalPath>SAK</SccLocalPath>
<SccAuxPath>SAK</SccAuxPath>
<SccProvider>SAK</SccProvider>
These lines are most probably created due to project is added to visual svn i.e. when project/solution is added to source control project/solution files are updated to include source control integration info and these lines are added which causes issues.
Delete these lines and just reload your project (or solution), this should fix issue.
Is anyone aware of a way to make visual studio completely ignore a file when compiling? I have a C# solution that has a foo.config file that isn't really a standard config file - it's just a text file. During compiling VS grabs a hold of the file and bombs.
I'd like for it to act as though it's just a text file. I do not have the option of changing the name of the file.
EDIT: Please note that BuildAction does not exclude files from the compiler checking them. It simply decides if the file is compiled into the assembly, whether it's content (like a jpg or something), or whether it is a resource file. For more info: see the MSDN page.
EDIT2: Apparently, if you have a text file that is named foo.config and you have it open while building, VS2005 will pop up an error thinking that the file should be xml. However, if you close the file, VS2005 will ignore it.
Solution: Visual Studio validation causes errors if you have a non-compliant file open during build time. For an example of how to turn this off (for HTML), see Scott Guthrie's post. As Allen mentioned, you should also have the Build Action turned to "None". Unfortunately, this will not stop build errors if you have the file open.
right click > properties
Build Action: set to "None"
Edit: If you're talking about app.config, you really cant mess with the format of that, you need to put it in a different .config file.
I just double checked, VS.net doesnt care as long as its not app.config or web.config and the config file build action is set to "None", it will "error" if you have the file open but it will not cause the build to fail or keep it from building the assemblies.
Close the file and the errors will go away, similar to the errors you get about HTML markup. The displaying of these "errors" is probably a configurable setting in vs.net
The action to take depends on the solution and and file type. For instance (in VS2005), in a C++ solution I can right click on the source file name in the solution explorer and view its properties. The first "General" option is "Excluded From Build", which will allow you to exclude the file from the build process without having it excluded from the project altogether.
I pulled up a .config file in a C# solution, and found a "Build Action" option under the Advanced section. That should probably be set to "None".
Just right click on the file and choose "Exclude from project".
If you still want to see it in your project, select the project and click the "Show all files" button at the top of the solution explorer. This will show all the files in the directory tree even if they aren't actually part of the project.
Are you sure that VS compiling .config file???
You should check it's Build Action in file options and may be set it to none.
