INI File Store

To configure the store:

IMySettings settings = new ConfigurationBuilder<IMySettings>()
   .UseIniFile()
   .Build();

The store supports reading and writing, as well as INI file sections.

In the simplest form every key in the INI file corresponds to the name of an option. For instance a definition

string MyOption { get; }

will correspond to a line in an INI file:

MyOption=my fancy value

Using Sections

A section corresponds to a part of option name before the first dot (.), for instance

[SectionOne]
MyOption=my fancy value

should use the definition

[Option(Name = "SectionOne.MyOption")]
string MyOption { get; }

Writing is straightforward, however note that if an option has a dot in the name a section will be created by default.

Both inline and newline comments are preserved on write:

key1=value1 ;this comment is preserved
;this comments is preserved too

There are a few edge cases when working with INI files you should know about:

A value can have an equal sign (=) and it will be considered a part of the value, because only the first equal sign is considered as a key-value separator.
Apparently key names cannot contain =
If a value contains semicolon (;) which is a comment separator in INI files you should add it also as a last character in the value, because the parser considers only last ; as a comment separator. For example key=val;ue wil be read as val, however key=val;ue; will be read as val;ue.
