<p>The "core" .NET languages are integrated into VS2008 - C#, VB.NET, and C++. I'm not sure about current support for J# and JScript.</p>
<p>But there are a number of other .NET languages out there - A#, Boo, Oxygene, F#, IronLisp/IronScheme, IronPython, IronRuby, Nemerle, Phalanger, P#, PowerShell, and <a href="http:... | <p>I suspect it's pretty simple: IDE integration is no simple task, if you want to do it well. I would guess that most of these languages are done in spare time rather than having commercial funding. The amount of effort required is just prohibitively expensive - and not necessarily due to Visual Studio making things p... | <p>I do agree it would be nice if there were a little broader language support in VS. However, I think they should add support some other non-.NET related languages too. It would be nice if there were support (even if only added via a downloadable addon) for interpreted languages like: Ruby, PHP and Classic ASP.</p>

<p>After a repository is imported from VSS to SVN, there are some files which I guess might be VSS specific - .vsssc and .vssscc files for the solution and .vspscc for projects. They seem to be related to VSS project binding. Are they needed (or useful) for SVN as well?</p>
| <p>The .vsssc and .vspscc files contain references to the visal sourcesafe server in which the solution/project was kept. Subversion doesn't need this information as this information (and more) is stored in the .svn areas of your working copy.</p>

<p>After making it through the major parts of an introductory Lisp book, I still couldn't understand what the special operator <code>(quote)</code> (or equivalent <code>'</code>) function does, yet this has been all over Lisp code that I've seen. </p>
<p>What does it do?</p>
| <p><strong>Short answer</strong>
Bypass the default evaluation rules and do <em>not</em> evaluate the expression (symbol or s-exp), passing it along to the function exactly as typed.</p>

After plowing through way too many explanations of what quote <em>doesn't</em> do, that's when the light-bulb went on. If the REPL didn't convert function names to UPPER-CASE when I quoted them, it might not have dawned on me.</p>
