Microsoft.Configuration.ConfigurationBuilders.Json 3.0.0

SimpleJson ConfigBuilder

This package provides a config builder that draws its values from Json file. It comes without many frills, but does offer the ability to treat the entire Json file as a single flat config source or as a set of config sources broken into flat sections at the first level. More comprehensive documentation exists at the MicrosoftConfigBuilders project.

The basic usage of this builder is given below. Parameters inside []s are optional. Parameters grouped in ()s are mutually exclusive. Parameters beginning with @ allow appSettings substitution. The first line of parameters are common to all builders and optional. Their meaning, usage, and defaults are documented here. They are grouped on one line for brevity. When a builder uses a different default value than the project default, the differing value is also listed. Builder-specific settings are listed on each line thereafter followed by a brief explanation.

V3 Updates:

A more complete list of updates lives here. These are the ones most relevant to this builder:

• ⚠️ Breaking Change - Expand mode is gone. It has been replaced by Token mode.
• Json use has migrated to use System.Text.Json instead of Newtonsoft.Json.
• optional attribute is obsolete ⇒ enabled attribute which provides more versatility. (The optional attribute is still parsed and recognized in the absence of the newer enabled attribute, but builders should migrate to use the new attribute name when possible. Installation scripts should try to handle this automatically.)

V2 Updates:

A more complete list of updates lives here. These are the ones most relevant to this builder:

• ConfigBuilder Parameters from AppSettings - This has been one of the most asked for features of these config builders. With V2, it is now possible to read initialization parameters for config builders from appSettings. Read more about it here.
• [[Obsolete]] This has been superceded by the enabled tag. (Base Optional Tag - The optional tag that some of the builders in this project employed in V1 has been moved into the base class and is now available on all key/value config builders.)
