it seems ASP.NET MVC3 project cannot be opened in a (MVC3 + MVC4) environment.
we have a shared development environment which has both MVC3 and MVC4 environments (VS2010 and VS2013 on Windows 8.1)
and I was trying to open a MVC3 project using visual studio 2010, and I got an error "The project type is not supported by this installation."
I checked project type list in the project file.
<ProjectTypeGuids>{E53F8FEA-EAE0-44A6-8774-FFD645390401};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
Also, I checked the reference to System.Web.Mvc.dll and it is pointing to C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 3\Assemblies\System.Web.Mvc.dll, and the physical dll does exist.
I have other projects which have <ProjectTypeGuids>{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids> only,
and they are all loaded fine in VS2010.
it seems the issue is about ASP.NET MVC 3 {E53F8FEA-EAE0-44A6-8774-FFD645390401} in VS2010 with MVC4 installed.
I can't upgrade the project and have to use this MVC3+MVC4 environment.
Any ideas of how to load MVC3 project in a (MVC3 + MVC4) environments?
thanks a lot.

As CodeCaster suggested, I removed MVC3, and reinstalled, but it doesn't help.
But I found the other way to trigger web platform installer to 'repair' the environment. I am not sure if this is a typical case, but If you did try all kind of ideas to load a MVC3 project in a MVC3+MVC4 evnriroment, but don't work.
you can try this one.
my case is in the project file, we have ASP.NET MVC 3 {E53F8FEA-EAE0-44A6-8774-FFD645390401} in the project type already, and we have MVC3, Visual Studio tools and ASP.NET Web Pages installed, but we still can not load MVC3 project,
the error is "The project type is not supported by this installation.".
and if you launch web platform installer, it tells you "... already installed."
if this is your case, try what we just did, it seems can resolve the issue.
1) manually open the project file, remove {E53F8FEA-EAE0-44A6-8774-FFD645390401}, and compile the project, you should be able to compile the project, because you have MVC3 environment installed.
2) then manually open the project file again, add back {E53F8FEA-EAE0-44A6-8774-FFD645390401}, and open project, I remember I waited for about 10 seconds,
and it showed up a message about missing "Microsoft ASP.NET web Pages - Visual Studio 2010 Tools" (actually in control panel => program list, it got installed already), and ask me to install it using ASP.NET install consol. I clicked yes, after the installation is done, I can open the project and compile it.
Hope this helps your case.
In general Mvc3 is not supported after VS2010,I use VS2010SP1 btw.
You may make it work but it will bite you in the end.
So i recomend choosing matching VS and MVC versions(check the official microsoft site to see the connenction)

I want to create an Asp.net Core project with Visual Studio 2017 Community but the Solutions explorer says that I have (0 projects).
I tried selecting an empty project, web application, web application (Model-View-Controller) but the Solution explorer still displays (0 projects).
When I go-to Debug I see the "Attach to Process" option. There is no option to start of course since I have no projects.
What could be the issue?
Have you installed everything correctly? To verify this, open a normal cmd and just type 'dotnet'
Only if the command runs, printing out information about how to use dotnet, you're good to go.
Have you installed the correct .NET SDK? What version of it? Make sure the version is compatible with the version of visual studio you have installed.
Follow this link for step by step setup instructions:

This could be the same problem, but I had the same issue during College once but this time I had the support for the web components, so I went back to the installation and repaired it. It downloaded the missing files and it worked again and it took a while.
Let me know if that works or not.
I am missing the usual publish targets when publishing my c# web application. The usual "Import" and "Custom" options are missing when I go to publish, as well as the "Manage Profiles" drop down that has the option to create a new profile.
Here is the screen I am presented with.
The buttons on the left hand side are "greyed out"
Here is another screen from a colleague that has the missing options
I have tried a full reinstall of Visual Studio 2015 update 1 with no success. I have also tried creating a fresh ASP.NET Web application project in a new solution resulting with the same problem.
In the end this ended up being a corrupt publish profile file in the Properties/PublishProfiles/xxxx.pubxml within the project.
There are multipy options for this behavior:
Issue with the Web Deploy Tool
Try to reinstall the current Web Deploy 3.5 Tool
Depending on the exact Version of your Visual Studio and your Operating System
There are known issues about specific OS/Visual Studio combinations.

I'm developing a small website and I decided to try ASP.NET MVC 6. I wrote some code on my computer and now I want to test it on the server, first in Visual Studio to debug it. I copied the whole solution folder and pasted on the server, but I cannot run the project. VS complains:
The selected debug option is IIS Express but this project is not a web project. To use IIS Express you need to add the wwwroot attribute to project.json.
Google returns nothing for the error message, which is always a bad sign. Apparently there's a problem with the wwwroot folder, but I don't understand what it's trying to tell me. Note that the wwwroot in the solution explorer is displayed as a normal folder (as opposed to the globe icon I have on my dev machine).
I created the project from the template and everything was working out of the box. Did I miss something when copying the project?
Found it. It turns out that ASP.NET 5 runtime was not installed at the server.
When server knows when to compile project ? If I change aspx file it detects changes and compile it on request ? What about changes in cs file ? Thanks for any help
Basically, it depends on your project type.
Web Site projects are compiled on the fly and any code modification in the site folder will trigger recompilation on execution.
Web Application projects need to be manually compiled (you'll see a [your project assembly name].dll in the bin folder).
Also, check http://msdn.microsoft.com/en-us/library/dd547590.aspx for more information about the difference between the 2 project types (and how they are compiled).
Using VS 2010 you may create ASP.NET Web Application or ASP.NET MVC Application using .NET 2.0 - 4.0 of your choice.
The next details are applied for both ASP.NET Web Application and ASP.NET MVC Application:
aspx files most of the times contains only static HTML code and after you change it you don't need to recompile the whole project because server pickup your updated aspx file strait away. With cs files is different story, because in that case when you did any changes in cs file you need to compile it to produce new updated dll files which would contain your latest changes.
So if you did any changes in your cs files and did not recompile the project, your changes won't be available until you recompile the project.
Also using VS 2010 you may create ASP.NET Web Site application. In that case you don't need to recompile your project if you changing cs file. Your source code will compiled automatically by ASP.NET on the server after first request.
More about Summary of Differences between ASP.NET Web application projects and ASP.NET Web site projects you may find here: http://msdn.microsoft.com/en-us/library/dd547590.aspx
With all the project types that exist in Visual Studio 2010 you have to recompile your code every time you make any changes in your .cs files.
In VS 2005 and 2008 there was a project type named "Web site", with this project type you did not have to recompile if you made changes in a code behind file.
For more information check out the differences between CodeFile and CodeBehind.

Every time I use Setup & Deployment to create a new Web Setup, and run it (after edit all the nice things in the properties), the output is always a copy of the Web Site project...
How can I output a PreCompile version of the WebSite project?
What I did was, publish the Web Site (so I get the precompiled version), add this new precompiled web site as an existing Web site to my solution and add it to the content output of the Setup...
well, the idea was good but I get an error saying:
"This application is already precompiled."
alt text http://www.balexandre.com/temp/stackoverflow_precompiledquestion.png
:-(
Bottom line is that I just want a Setup file that gives me the precompiled version of my Web project, how can I accomplish this?
I see you tried the standard Web Setup project from VS.
Scott Gu's blog post takes you to this page:
Visual Studio 2008 Web Deployment Projects
which is a plugin for Visual Studio that activates an additional "right click" option to any Web Site project to add such a deployment project. You can see here what I created.... And the output is a pre-compiled web application. Now, if you add a regular Web Setup project to your solution, and point it to the previously created Web Deploy project as its content, ... I got a valid build, no errors and an MSI file was created...with dlls inside it.

I hope this helps you.
I was searching for this solution from google for long days. What i did is i precompiled my website to one folder and added that folder as a new website to my
solution(While adding it will give a warning message that it was already precompiled content. No probs). Now add this project output to the my setup project and one more important thing is in my web deployment project i just disabled Building of my precompiled
website.
I just got my thinks working. If you want you can try that.

you may be having "PrecompiledApp.config" file in the root of your web application (please check in solution explorer).
I faced this issue and removed "PrecompiledApp.config" from solution explorer and solved the issue.
