<p>In Eclipse, I have a workspace that contains all of my projects. Each project builds and compiles separately. A project does not interact with another project.</p>

<p>How does this relate to Visual Studio and Projects/Solutions there?</p>

If you had a Solution with one Project, you could open the Solution and see the one Project. If you opened the Project, it would try and create a new Solution file to contain the Project. But web projects and Winform projects all had Projects and Solutions.</p>\n\n<p>In VS2005 this changed a bit - by default now, Web projects no longer had Project files. They had received feedback from some web developers that didn\'t like Project files - their take was that if a file is in the directory, it\'s part of the app. After VS2005 shipped, they got more feedback from developers who did like the Project file notion, so they patched it back in. This is "Web Site" versus "Web Application" in VS2005 (and I can\'t remember which is which now).</p>\n\n<p>In addition, in VS2005, if you have a Solution open with only one Project, you won\'t see in the Solution Explorer that there\'s even a Solution at all, you\'ll only see the Project (as if it was not in a Solution). Only after adding the second Project will you see that there\'s a Solution containing them both.</p>\n\n<p>So basically you were on the right track - Solutions and Projects work the same in Visual Studio as they did in Eclipse, it\'s just some quirks that make things confusing.</p>\n'}, {'answer_id': 57654, 'author': 'Pete', 'author_id': 3059, 'author_profile': 'https://Stackoverflow.com/users/3059', 'pm_score': 0, 'selected': False, 'text': "<p>There are way too many kinds of web projects in Visual Studio 2008.

Even within the Web site Project option, there are at least 3 different ways to compile your application.</p>\n"}, {'answer_id': 231598, 'author': 'Jeremy Bade', 'author_id': 13284, 'author_profile': 'https://Stackoverflow.com/users/13284', 'pm_score': 0, 'selected': False, 'text': '<p>I found that not always seeing the solution in the Solution Explorer to be irritating.
