I just started learning unity and I created a project. But my project doesn't have a sln file included in. Every time I create a C# script and open it in Xamarin Studio I can't have any intellisense.
Is it normal not to have sln file in unity project?
If not, how can I add solution file to project?
Why that happened?
If "Open C# Project" doesnt create the .sln file, try updating your external tools first.
In Unity, go to Edit > Preferences, and make sure that Visual Studio is selected as your preferred external editor.
This created the sln file for me.
I finally found the answer.
I closed Xamarin and inside Unity went Assets > Sync MonoDevelop Project Doing this created the two .sln projects: -csharp.sln and .sln
For people looking for answers on newer versions of Unity you may have to build your C# project.
To do this go into File > Build Settings then select the option Create Visual Studio Solution. Then build that and your file explorer will ask you for which folder you want your visual studio solution to be placed into. Then Visual Studio should behave correctly.

First install windows build also in unity hub then select target platform to windows. and now you can see visual studio solution checkbox.

Like the post by SSchmid suggests, go into preferences and have Visual Studio as your preferred editor.
I was having a sync issue and the Solution wasn't showing the name of the unity project, ultimately interrupting intellisence.
Found in my settings that the code editor was set to General and not Visual Studio specifically.
Setting it to VS solved it for me.

I'm opening a solution that was apparently built on Visual Studio 2003 (not sure, I don't know anything about it) and trying to migrate to 2010. When trying to migrate I get the message:
the application for project '' is not installed make sure the application for the project type (.csproj) is installed.
If I open each one of the single projects of the solution they migrate fine but not the solution itself.
Right-click on the project file, then "Reload"
If your solution opens, but your project is showing as "incompatible", it may need to just reload. This worked for me when running an update from VS, and it did not recognize my njsproj
I know this is an old question, but it is still occurring in VS 2013.
I had an old VS 2003 web application. I opened it in VS 2013 (Ultimate) and had the error message:
Could not find the server on the local machine.
Creating a virtual directory is only supported on the local IIS server
along with
The application for project is not installed.
Yes, I am upgrading, and yes, I don't have some other elements ready. Giving me errors is fine - but why are you not completing the migration/load of the project. I can't fix the other issues if you don't LOAD ANYTHING! You loaded the subprojects, and then you told me that I should choose a later .NET Framework. Great, I did that. So why didn't you just finish loading the main project and let me fix the errors?
Lots of attempts to fix this failed. My final solution, just to get the project loaded was {arrow pierces chest, dies with Arghhhhhh on his lips}...
I located the {project}.csproj file. I found the <Reference> sections. The paths to the .NET Framework components were no longer valid and referred to old versions no longer installed (yeah, upgrading, remember?). I manually changed the paths to refer to .NET Framework 4.5 components. The project still didn't load.
Then I located the {project}.csproj.webinfo file. It referred to http://localhost/{stuff}/{project}.csproj, so I just set it to {project}.csproj. No luck. Then I just renamed the webinfo file to hide it. Eureka, the project was hot!
The project loaded, I got the "You have completed the first step in converting your Visual Studio .NET 2003 web project. To complete the conversion, please select your project in the Solution Explorer and choose the 'Convert to Web Application' context menu item." Which, of course, is not present, but is present as the very last item in the Project menu. Then I got the "This action will add designer and code behind files required for converting Web site projects to Web application projects. Do you want to continue?" You bet your posterior I want to continue! And now I have a project I can actually start to fix. Thanks, Microsoft, for the informative error messages.
If your projects individually migrate fine, then create a new blank visual studio 2010 solution, and add new projects individually (right click on solution->add->existing project)
But I'm not sure that your projects will load fine individually. There are project types that require some additional software to be installed in order to be supported. The most frequent problems I face are old projects built with old versions of asp.net mvc (1 or 2) and I have asp.net mvc 3 installed...or really old projects built with asp.net ajax...In those cases, you have to install that additional software and then import project, or find a tool to upgrade that project type to a newer version.
I found a solution that worked for Visual Studio 2017.
In Visual Studio, go to Tools > Extensions and updates. At the upper-right search box, search for "integration". It should come up with Analysis or Diagnostic Tools (or similar). Click Disable, then Enable. Exit the dialog, and close Visual Studio. Relaunch and open your solution again. Your projects will still complain they can't be loaded because of incompatibilities, but now you can right-click them individually and select "Reload Project" and they should load fine.

Adding this answer as reference for people who landed here for missing ".smproj" file.
This issue can arise due to various project files missing. For me, it was because of ".smproj" file missing which is Project file for SQL Server Analysis Services(SSAS). I re-installed SQL Server Data Tools (SSDT) and restarted the Visual studio.
Originally Answered here
Sometimes the SSIS or SSAS Extension in "Manage Extension" is disabled in the settings and must be Enabled manually. And then restart Visual Studio
It happened to me as wel.
You usualy do really need only to reload project in the solution. But in some cases you maybe:
didn't install SQL Server Data Tools (SSDT) for VS
have to enable SQL Server Data Tools manualy in the Extensions
If you have both things settled then try to reload project again. This happened to me when I moved from VS2019 to VS2022 and extension was somehow disabled.
I am using visual studio 2019 and I was faced with this issue when I reopened my ASP.Net webform App in visual studio after modifying for install SSDT.
this problem happens when Visual studio packages will modify (Especially when SSDT will be installed).
To solve this problem you have to go to you project folder and looking for the folder that named '.vs', this folder is hidden.
Deleting these folder will solve the problem because after that when you will open your project with visual studio, it will create the folder again.
Adding this for those who face issues for SSRS projects in VS2017 from earlier version as this comes up in google search.
In Visual Studio, go to Tools > Extensions and updates. Download the below :
Microsoft Reporting Services Projects
Microsoft RDLC Report Designer
In SSIS 2017, t the upper-right search box, search Microsoft Integration Services Projects.
go to Tools > Extensions and updates.
Enable -"Microsoft Integration Services Projects"
This will help to resolve the issue re-launch the SSIS
For my case, I disabled this extension and turns out, it is needed.
Enabling it resolved my problem.
In VS2019 Before you try any of the above right click the solution and click "Resolve Errors" no kidding that made my tabular model solution being available again.
For me what worked was a variation of #vapcguy solution.

Follow comment on Paul Potter's post by Albert Romeo
Integration Services Plugin was disabled(as explained before: Goto Tools > Extensions and updates > and search for integration/analysis/reporting and enable application
I had to enable integration services, then reload project. I don't know why since I've been using the same SSIS project several times a week for months.
Can someone briefly explain to me the difference between Visual Studio's solution file (.sln) and project file (.vcproj).
It seems to me opening either one open the correct solution/project in Visual Studio. Is one the super-set of the other?
Note: I am currently using Visual Studio 2008 working on a project that was brought forward from Visual Studio 2005 (I believe).
A solution is a set of projects. If you need more than one project in your software, then go with solutions. I.E.: A Class Library Project + A Web Application Project.
A project file typically corresponds to a single module: EXE or DLL or LIB. A solution manages a collection of project files.
A solution is a collection of projects. Visual Studio is made so that it cannot function without a solution, so if you open a bare project, it will generate the solution automatically (or try to find one).
One solution can contain zero or more projects. Everything is in projects, so a solution with zero projects doesn't contain anything at all besides the solution properties.
Visual studio keeps track of where the projects are used, so if you open a project file, it will open (IIRC) the last solution where it was used.
When you create a project from scratch, a solution is also created, but it's not shown until you add another project to it. It looks like you have only the project open, but it's actually a solution containing the project that is open.
Specifically project files are intended to contain the data required to build the files in the project into an exe or dll. This file is utilized by the local compilers or with systems such as Team Foundation system and server side build agents.
Solutions are a client (IDE) construct designed to manage collections of projects, which in effect is a collection of different build definitions and associated files.
Solution files are typically made up of multiple project files.
I am debugging someone else's work and the solution is quite large. When I try to build the entire thing, several projects within the solution don't build and just skip. Viewing the output window during the build process says:
1>------ Skipped Rebuild All: Project: pr1lib ------
How can I determine why these builds were skipped? I am unable to find additional output.
This is with VS2008 and the solution is comprised of c# and c++ code.
Right click the solution, choose Properties and then Configuration Properties. Here you can choose which projects to build.
[edit]:
See Kdt's comment: ... when I looked in configuration properties ... the project build target was configured for "Mixed Platforms" while the solution was set to build "Any CPU".
*When this problem happened to me, The main project only had 'Any CPU' and it set the child dll to 'any CPU' too, however, I'd deleted that profile and left only 'x86'. Picking x86 for just the dll make it start working
[/edit]
Build, rebuild, and clean operations were being skipped. Unloading and reloading didn't help, and neither did restarting Visual Studio.
Once I removed the project from the solution and added it back, it is no longer skipped. To remove it, in Solution Explorer, right-click the project > Remove > OK. To add it back, in Solution Explorer, right-click the solution > Add > Existing Project and select your project
I just had the same problem- "unload project" and "reload project" solved the issue !
Restarting Visual Studio did the trick
If the confixguration is x64 and the x64 compiler isn't installed it will skip the project.
My solution is the same as mentioned previously: Delete -> Add existing project
But this solution implies that references between projects get gone
To avoid re-adding references: and in case if you use version-control system like GIT or TFS or whatever, it is possible to acheve goal with the following steps:
Make shure that all the changes are commited / checked-in before the operation
Go through all projects deletting them from solution and adding-existing them
Notice that the .sln file has changed
Keep the new .sln file, but undo the changes to all the .cspoj files with the version-control system
I had a weird one that may be worth documenting amongst the other possibilities here..
I'd added a Shared Project to my solution, with code that was used in two or three of the other projects. As you're aware - Shared Projects are just code, and not really a project in the traditional sense.. You can't 'build' a shared project, it's just code that is embedded into the other projects, and then built there.
But somehow my solution file had been updated as if the shared project was it's own thing that needed building. I'm guessing then that any time I was trying to build and I hadn't changed the code in the shared project, then it figured 'nothing has changed, skip those builds'
I found the shared project in the solution.sln file like:
Project("{D954291E-2A0B-460D-934E-DC6B0785DB48}") = "Api.Common", "Api.Common\Api.Common.shproj", "{EC580471-D78A-4509-AC46-BD565553AD60}"
..which is fine. What isn't fine is that this project also appeared in the GlobalSection(ProjectConfigurationPlatforms) = postSolution like:
{EC580471-D78A-4509-AC46-BD565553AD60}.Debug|Any CPU.ActiveCfg = Debug|Any CPU
{EC580471-D78A-4509-AC46-BD565553AD60}.Debug|Any CPU.Build.0 = Debug|Any CPU
{EC580471-D78A-4509-AC46-BD565553AD60}.Release|Any CPU.ActiveCfg = Release|Any CPU
{EC580471-D78A-4509-AC46-BD565553AD60}.Release|Any CPU.Build.0 = Release|Any CPU
I removed those four lines from my .sln file, and now things seem happy again
The visual studio 2008 , it can be because 64 bit compiler wouldn't have installed.
Control Panel --> Programs and Features -> Microsoft Visual Studio 2008 professional --> [double click]
On Visual Studio Dialog
Next --> Add/ remove Features --> (Under) Visual C++ --> (select) x64 compiler and Tools
The first thing you need to do is diagnose why the build is skipping projects. So to get a detailed build output change the verbosity to detailed in the following place in Visual Studio.
Problem exists in VS 2010 as well; of the proposed solutions: editing build config, cleaning, changing/re-changing target framework, do NOT work. But unloading and reloading the project does.
I've just had this issue, and was able to resolve it by removing the hidden .vs folder in the topmost folder. After restarting Visual Studio everything worked again.
Hey, just fixed this one. Thought it might help. You most likely didn't install corresponding compilers along with the visual studio. This happened to me today - by default, VS 2008 installer doesn't install x64 C++ compiler.
If you have SP1, uninstall it before changing VS installation. When done, install SP1 again.
Close visual studio
Open the sln file with notepad
delete all of the things like this :
{B546C55D-9321-4FC0-B25C-46844222BEBE}.Debug with
Fakes|x86.ActiveCfg = Debug with Fakes|x86 (there will be a bunch of
them)
4.save the file
5.open visual studio and all better
Go to the build menu and choose "configuration manager". This will show which projects are configured to build in your selected configuration.
I had a similar thing just happen to me. I'm not sure what the problem was, but it would not Clean, Build, Rebuild, etc. I am operating in Visual Studio 2017 and wanted a netstandard2.0 assembly. The issue for me was that somehow the project type was incorrect, maybe I started from a netcoreapp class library, something like that, stuck in the Solution file, I do not recall. Anyway, I backed up the project, created a new netstandard class library project, and factored in the backed up bits, and that fixed it for me. HTH someone.
i updated to 15.9.11 , ... after some builds, same problem:most projects are skipped (which build a second ago without problems). Unloading/reloading the solution helps always in my case, but it will happen again soon.
I have no idea why... except a big bug in VS2017
I checked configuration manager , all checkmarks are set to build.
Maybe, it has something to do with nuget packages, but that is just a guess
The solution has only c++/vcxproj, no csproj. 64 and 32 are installed both
This happened to me in VS 2019, and the solution was to simply restart visual studio.
My build configuration was never modified.
I checked-in my project to source control from one computer and downloaded it to another and it will not build properly there. It will skip building projects and didn't even create the master \Debug folder for outputs.
The solution (VS2019) is to right click on solution and select Configuration Manager.
I saw the build checkbox was not checked for two projects that I was building (shown below). I don't know why they were unchecked but checking them and building project worked!
Right click on solution ->Remove then Add the existing project, this worked for me.
Had the same problem, found out that the project setting was for Itanium CPU, changing it to Intel fixed it.
Was running into the same problem with VS2005, all the configurations were correct .
It was even skipping the Clean project command.
Finally Unloading /Reloading did the magic.
Right click on Solution at at your solution explorer, then, click on Property at bottom of the menu. In the property windows, click on Configuration Properties -> Configuration on the left pane, you will see the list of projects on right pane, make sure Build check box is checked in the popup window.
If your solution contains a NuGet project (*.nuproj) file, try unloading it and then rebuilding your solution.
This worked for me after none of the above worked.
I had similar problem, I had one project which could not load in solution explorer due to some reason. When I loaded that project it worked like a charm.
I find that sometimes when you have target platform as set to lets say x86 in your solution and in your projects the project does not actually always had it selected.
To double check go to the project properties and see if you can select that platform in the Build->Platform setting if you can not then you will need to go to the configuration manager and create that configuration.
I had this problem with some Windows CE projects on a new PC. "Unload project" and "Reload project" appeared to fix the problem, but actually Visual Studio had simply switched to a different platform and built that.
It turned out that although my WinCE platform was shown as the active platform, Visual Studio didn't "really" see it. The solution was to reinstall the WinCE SDK with administrator priveleges:
Make sure Visual Studio 2008 is not running.
Open a “Visual Studio 2008 Command Prompt” as Administrator. On Windows 7 just right click the short cut and pick the “Run as administrator” option.
Enter the following command: msiexec /log SDKInstallLog.txt /package <the path to your .msi file>
When asked if you wish to do a custom or complete install pick custom, and instruct the installer to omit the installation of the documentation (this step was not necessary in my case; in fact I just asked it to "repair" the existing installation.)
Install
VS 2008 will skip x64 targets if you don't have the x64 compiler installed. VS 2008 does not by default. Kind of a duh, thing.
I had a very similar issue after generating a project from a decompiler from Telerik, then trying to recompile it. The project was skipped whenever I tried to rebuild it. Tried a lot of the suggestions above, but for me, it was the .NET Framework selected in the project properties.
Right-click project in solution file, select properties, application tab, change target framework from 4.0 to 3.5.
Then, rebuild, and I got a bunch of assembly reference missing errors, which makes sense since I haven't added references to them yet.
I update one small update of Visual Studio 2017 and then the installer reminds me to restart my computer,but I did not restart.When I build my project or solution in Visual Studio 2017,I meet the same above problem.I guess the update maybe the key,so I restart my computer,I did it.:>
I had this problem in Visual Studio 2017 15.9.4 and after some searching and putting some time I found out that in my solution the .csproj file of one of projects got corrupted after merging in TFS. (I could build other projects by unloading the problematic project from solution).
How I resolved my problem was that I compared the .csproj file before and after the merge and do fix that. And by fix I mean since my own project's type was .netStandard I removed unnecessary lines including Configuration PropertyGroup, all and others in the new .csproj file to make it similar to previous .netstandard-style version.
