When I try to open an application to debug a problem I get the following error from VS.NET....

Visual Studio .NET cannot create or open the application.  The likeliest problem is that required components are not installed on the local Web server.  Run Visual Studio .NET setup and add the Web Development component.

Right now I have the website setup to run on a remote server.  When I debug or mainting I just open the file locally via a mapped drive to the remote server and make changes (or at least I would if I could get VS .NET to open it).  Can anybody clue me in on what component I might be missing and on which server it should be installed?

If you open .sln file in notepad you will find a path like

"http://localhost/CommerceVBVS/CommerceVBVS.vbproj"

what this does is locates the project file at location "http://localhost/CommerceVBVS/" and it is not finding this application at that path. because of that it is giving error.

Solution:
1) Copy whole code on local machine, run and test it. and put the code back to server.
2)  change your IIS setting and make the mapped application ur web site root folder and make virtual directory as necessary.

Option 1 is the best solution.

Just in case it helps anyone out there.  In my case, the solutions above did not work.  I kept trying different things from sites all over the web and none seemed to take care of the problem.

What I ended up doing is to create a new blank solution in the remote (new) environment and just re-add all the projects to it and bingo - it worked.  My original solution file, for some reason had something that the new environment did not like (at least that's my guess)

 I was working with a customer today on an issue.  The customer had a custom VS project that he had inherited from another developer who had since left the company on other pursuits.  While the original developer could work in the solution just fine, the new developer was receiving the following error message

• Visual Studio .NET cannot create or open the application.  The likeliest problem is that required components are not installed on the local web server.  Run Visual Studio .NET setup and add the web development component.
