I am using Visual Studio 2015 to open a C++ CLI project and I want it to target .NET 4.5. My installed .NET version is 4.7. But I cannot edit the project's target framework because it is grayed out.
I have tried to directly edit the project's file in notepad but I couldn't find where the target framework is defined.
Below is part of the screenshot of the .vcxproj file
To complete Hao Peng's answer.
Right click on project.
Select "Unload Project"
Right click on unloaded project.
Select "Edit *.vcxproj"
Modify the "TargetFrameworkVersion" tag from "v4.7" to "v4.5"
Save and close the file
Right click on unloaded project
Select "Reload Project"
This feels a bit hacky; nevertheless, it worked for me. I moved from 4.5.2 to 4.5. YMMV.
In Visual Studio, in Solution Explorer, select your project. On the menu bar, open the Project menu and choose Unload project. This unloads the project (.vcxproj) file for your project.
In my case, I had this issue, while doing migration from .netframework to .net core.
I have multiple projects in my solution, of which base project was created with output type as Class Library and Target framework is set to '.net5.0-windows' by a tool and the other projects are created as '.netstandard 2.0'. Though the dependent projects are configured correctly in .csproj, the option in the properties is grayed out.
However, when I changed base project targetframework to '.netstandard 2.0' then the Target framework has all installed '.netstandard' versions for rest of the projects.
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.
For people looking for answers on newer versions of Unity you may have to build your C# project.
First install windows build also in unity hub then select target platform to windows. and now you can see visual studio solution checkbox.
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.
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.
A screenshot to help those who are too lazy to read.
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.

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.
there was a plugin for vs2010 that allowed to choose in a solution what project to load when the solution was opened, and what projects to keep unloaded. Anyone know how is named?
Was it Ankhsvn? http://ankhsvn.open.collab.net/
I have a solution in VS2008 containing C# and C++/CLI projects. There are 3 "solution platforms" in my solution:
Any CPU
Win32
Mixed Platforms
I never want to "just build the C# ones" or "just build the C++ ones", I always want to build all projects. So the solution platforms metaphor is meaningless to me, I'll leave it on Mixed Platforms or whatever as long as they all build.
Now VS sometimes automatically switches the current solution platform to Any CPU (I'm not sure when or why). This means that pressing F7 will only try to build the C# projects, which is obviously no good. So I have to switch back to Mixed Platforms and try again.
So how to workaround this irritating problem? I have tried 2 ways:
In Configuration Manager, remove the Any CPU and Win32 solution platforms. This worked until I added a new project and Visual Studio very kindly added them back in... :/
In Configuration Manager, check all checkboxes for all projects in all configurations in all solution platforms. This becomes a nightmare to manage with many projects in the solution.
Any other ideas?
See the msdn:

Removing a Platform
If you realize that you have no need for a platform, you can remove it
using the Configuration Manager dialog box. This will remove all
solution and project settings that you configured for that combination
of configuration and target. To remove a platform
On the Build menu, click Configuration Manager.
In the Active solution platform box, select <Edit>. The Edit Solution Platforms dialog box opens.
Click the platform you want to remove, and click Remove.
At least on Visual Studio 2005: After removing it from configuration manager, it is also necessary to edit .vcproj as text file and remove any references to Platform manually.
