<p>How do you set up your .NET development tree? I use a structure like this:</p>
<pre><code>-projectname
--config (where I put the configuration files)
--doc (where I put all the document concerning the project: e-mails, documentation)
--tools (all the tools I use: Nunit, Moq)
--lib (all the libraries used by ... | <p>We use a very similar layout as covered in JP Boodhoo's blog post titled <a href="http://blog.developwithpassion.com/2007/10/01/directory-structure-for-projects/" rel="nofollow noreferrer">Directory Structure For Projects</a>.</p>
| <p>At my place of work we have multiple projects, where each project gets its own sub-directory, like so:

--proj1.csproj<br>
-proj2<br>
--proj2.csproj<br>
-proj3<br>
--proj3.csproj<br>
solutionfile.sln </p>

<p>At one point I run into this snippet of code:</p>

<p>I need to serialize the System.Configuration.SettingsProperty and System.Configuration.SettingsPropertyValue class object through WCF.</p>
| <p>Using your own class is reasonable option. You can also use the VS designer settings if you want. </p>

I would create a serializable class myself and load the properties there.</p>

<p>In XEmacs this is done by the calling the function char-to-ucs on a character. GNU Emacs does not seem to have this function. In GNU Emacs, characters seem to be ordinary integers. Running C-x = on a latin character reveals that the Emacs codepoint is different from the Unicode codepoint for the corresponding cha... | <p>In a modern Emacs, M-x describe-char will tell you about the character at point.<br>
An example:</p>
<pre><code> character: ¢ (2210, #o4242, #x8a2, U+00A2)
charset: latin-iso8859-1
(Right-Hand Part of Latin Alphabet 1 (ISO/IEC 8859-1): ISO-IR-100.)
code point: #x22
syntax: w which means: word
