⚠ Deprecated: Other
As I learned more about using the IHostBuilder/IHost API, I came to realize almost all of what I'd implemented in this assembly could be handled in the IHostBuilder/IHost system. Consequently, I'm deprecating my own assembly. J4JSoftware.DependencyInjection also contained an API for locating files. I've moved this to a new assembly, J4JSoftware.FileUtilities.
Suggested alternative: J4JSoftware.FileUtilities
provides customized IHostBuilder and IHost classes for simplified configuration

$ dotnet add package J4JSoftware.DependencyInjectionReadme
Dependency Injection
There are breaking changes in this release. Please re-review the github documentation.
Provides a customized IHostBuilder-based system for producing an IHost instance which contain a number of useful services. These include:
- logging (via J4JLogger)
- application and user configuration file management
- simple data protection (i.e., encryption and decryption of strings, via
Microsoft.AspNetCore.DataProtection) - command line parsing (via J4JCommandLine)
- dependency injection (via Autofac)
This assembly targets Net5 and has nullability enabled.
This example is derived from my GeoProcessor console app. However, it's been simplified to illustrate certain concepts more clearly and therefore will not work "as written".
