This ensures that your provider becomes an integral part of the overall configuration framework, seamlessly interacting with other built-in or third-party providers. This step is vital for achieving a cohesive and well-coordinated configuration setup tailored to the specific needs of your application.

Reasons to Opt for Custom Providers

Opting for custom configuration providers in .NET is a strategic choice driven by several compelling reasons that align with specific requirements and scenarios.

Custom providers cater to the need for specialized configuration sources. In certain situations, applications may necessitate fetching configurations from unconventional or proprietary sources that aren’t supported by standard providers. A custom provider allows developers to seamlessly integrate such unique data origins into the application’s configuration pipeline.

The decision to employ custom providers offers enhanced control over the configuration loading and refreshing processes. Developers can implement complex logic tailored to the application’s specific needs, ensuring precise control over how configurations are retrieved and updated. This level of customization is particularly valuable in scenarios where intricate business logic or dynamic configuration updates are essential.

Furthermore, custom providers address integration needs seamlessly. In cases where existing systems or external services play a crucial role in providing configuration data, a custom provider allows for smooth integration into the application’s configuration pipeline. This ensures that the application can leverage its existing infrastructure while adapting to evolving configuration requirements.

Opting for custom configuration providers empowers developers to tailor the configuration management process to the unique demands of their applications, providing flexibility, control, and seamless integration capabilities.

The Trade-offs Between Dotnet-Config and Custom Providers

The decision between adopting Dotnet-Config and developing custom configuration providers involves a careful consideration of trade-offs, with each option presenting distinct advantages and considerations. Key factors to evaluate when making this decision include:

The complexity of implementation is a crucial consideration. Dotnet-Config stands out for its simplicity, making it an excellent choice for straightforward configuration needs. On the other hand, custom providers demand a more substantial upfront investment in development due to the need to craft tailored solutions, especially when dealing with complex or unconventional configuration sources.

Maintenance overhead is a factor to weigh. Custom providers often entail a larger codebase, leading to increased maintenance requirements. Developers must be prepared to manage and update the custom provider codebase to address evolving requirements or changes in the application’s configuration needs. In contrast, Dotnet-Config, being a standardized tool, typically involves less maintenance overhead.

Another aspect is the balance between flexibility and standardization. Custom providers provide immense flexibility, allowing developers to implement highly specialized configuration solutions. However, this flexibility comes at the cost of potentially deviating from standard practices.

Practical Implementation Examples

Now, we place theory into practice. We’ll walk you through a simplified version of how you might utilize Dotnet-Config and also craft a custom configuration provider.

Using Dotnet-Config

To use Dotnet-Config in your application, install it as a .NET Global Tool:

dotnet tool install –global dotnet-config

Once installed, you could simply manage your configurations like:

dotnet config –local add “ConnectionStrings.DefaultConnection” “Server=.;Database=MyAppDB;Trusted_Connection=True;”

This sets a local configuration property. Dotnet-Config would now keep track of this setting across the applicable scope.

Creating a Custom Configuration Provider

Assuming we want to pull configurations from an API, here’s a skeletal code example in C#:

public class ApiConfigurationSource : IConfigurationSource
public IConfigurationProvider Build(IConfigurationBuilder builder)
return new ApiConfigurationProvider();

public class ApiConfigurationProvider : ConfigurationProvider
public override void Load()
// Logic to call your API and retrieve settings
// Populate Data dictionary with the settings

// In your startup.cs or program.cs
var builder = new ConfigurationBuilder();
builder.Add(new ApiConfigurationSource());
IConfigurationRoot configuration = builder.Build();

With this provider, now your application is capable of fetching configurations dynamically from a bespoke API.

Balancing Standards and Customization

Both Dotnet-Config and custom configuration providers have their rightful place in the .NET ecosystem. Dotnet-Config fills the gap for those seeking a standardized, straightforward, and cross-platform tool resembling the ease-of-use from git-config.
