I am developing a web project and I am not being able to test it using the IIS Express from the Visual Studio 2015.
I have googled this error and I found many references to it on the internet, but I believe that my case is different, because there is no other error message displayed besides "Unable to Launch IIS Express Web Server".
I've looked at the Windows Event Viewer and I got these errors below:
The worker process failed to initialize correctly and therefore could not be started. The data is the error.
The Module DLL C:\Program Files (x86)\IIS Express\aspnetcore.dll failed to load. The data is the error.
I also tried to launch the IIS Express directly using: c:\Program Files (x86)\IIS Express>iisexpress.exe /trace:error and I was successfull, so I think that the problem must be somewhere within Visual Studio and that my port (8080) is free.
Does anyone knows what else I can do?
If you are working with .NET core/ASP.NET core application then
please make sure you have installed these-
.NET Core SDK
VS 2015 Tooling Preview 2
If it is appeared to be solution-specific then-
Look for applicationhost.config file at <solution-name>\.vs\config\applicationhost.config location
Try removing this file and run solution again.
See if this helps.
I had the same error few days ago. I tried many things but i think Repairing DotNetCore.1.0.0-VS2015Tools.Preview2.exe fixed the issue.
Also, check whether you can run the web app in Kestrel web server. If you can run then worth checking web.config file for the presence of aspnetCoreModule tag properly.

I am currently trying to integrate typescript into vs 2010 by following these instructions for windows 7 described here.
Please do not mark this as duplicate because I am having a problem with the provided solution to my question and cannot comment on the solution.
I followed your instructions closely but sadly it's not working for me. During installation of typescript I get an warning from VisualStudio concerning devenv.exe: Invalid Command Line. Unknown Switch : updateConfiguration.
After clicking okay the installer reports that the installation was successful. when I start VS without creating or opening a project, after a while I am greeted with another error:
Confirming, that I do not want to get bugged about this again i create a new typescript(!) project, which gets denied with a more severe notification:
I checked all the folder paths I added as parameters to the .msi file and it looks like everything is in place. Any ideas how to resolve this?
Thanks!
I suppose there is a missing folder redirection in the answer you referenced, the VSTools msbuild folder is not being redirected.
If you open up the %programfiles%\msbuild\Microsoft\VisualStudio\v11.0\Typescript folder, is the target file present there? Try copying the whole folder to %programfiles%\msbuild\Microsoft\VisualStudio\v10.0\Typescript.
On a more serious note, Typescript is usually used for Web Development, Web development project types are almost 100% backwards compatible between VS2012, VS2013 and VS2010, so why not upgrade to make use of these features.
It can hardly be a support issue, since backhacking Typescript into VS2010 is surely putting you in the unsupported bucket.
I have a Build Server which is running TFS 2010 Build Service.
On my local machine I installed VS2012 alongside VS 2010. The Build templates worked fine prior to installing VS2012.
After I installed VS2012 I now have issues with the Build Templates when editing them in VS2010.
I have solved the IBuildDetail errors I were getting by visiting the following blog:
IBuildDetail Not Defined error fix
However i am trying to fix the remaining errors e.g:
Compiler errors encountered Processing Expression "New Microsoft.TeamFoundation.Build.Workflow.Activities.BuildSettings()".
"BuildSettings" is ambiguous in the namespace 'Microsoft.TeamFoundation.Build.Workflow.Activities.'
I more errors like the above.
Could anyone share how I could fix the above error/related errors please?
I would greatly appreciate it.
Faced the same problem when upgrading TFS 2010 to TFS 2012.
The exact problem:
Your awesome custom activities were built against TFS 2010 bits. Loading your custom assemblies in the TFS 2012 build service process triggers loading TFS 2010 assemblies, and the Workflow Foundation (WF) services are not happy about that.
Here is the steps to solve the problem:
Upgrading your build definitions from TFS2010 to TFS2012
And here workaround:
Your custom assemblies need update, or else, redirecting
May be I'm wrong about your case, but these links can drive you to your own solution.
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.
I have an ASP.NET web application that formerly published just fine to several locations. Now when I try to publish or package the application from Visual Studio, regardless of method (i.e., through the Build menu, through One-Click Publish, or the project's context menu), the operation fails with the following error:
Web deployment task failed. (Attempt by method 'Microsoft.Web.Publishing.Tasks.VSMSDeployDriverInCmd.LogTrace (Microsoft.Web.Deployment.DeploymentTraceEventArgs)' to access type 'Microsoft.Web.Deployment.DeploymentSyncParameterEventArgs' failed.)
Which doesn't give much guidance on how to fix it. I have reinstalled Visual Studio and Web Deploy to no avail. Tried disabling and even uninstalling my Visual Studio plugins - nothing.
Can someone give insight into the cause of this message and how to fix it? Or at least how to diagnose what the real problem is?
