What is ConsulSharp?

• ConsulSharp is a .NET Standard 1.3, .NET Standard 2.0 (and .NET 4.5) cross-platform C# Library that can be used in any .NET application to interact with Hashicorp's Consul.
• Consul is a service mesh solution providing a full featured control plane with service discovery, configuration, and segmentation functionality.

ConsulSharp is designed ground up, to give a structured user experience across the various Consul capabilities. Also, the Intellisense on IConsulClient class should help. I have tried to add a lot of documentation.

Give me a quick snippet for use!

• Add a Nuget reference to ConsulSharp as follows Install-Package ConsulSharp -Version <latest_version>
• Instantiate a IConsulClient as follows:

IConsulClient consulClient = new ConsulClient(consulUriWithPort, consulToken);
var managementTokenId = await consulClient.V1.ACL.BootstrapAsync();

Gist of the features

• ConsulSharp supports every API supported by Consul.
• These capabilities are bucketed into:
  • ACL
  • Agent
  • Catalog
  • Connect
  • Coordinates
  • Events
  • Health
  • KV Store
  • Operator
  • Prepared Queries
  • Sessions
  • Snapshots
  • Status
  • Transactions
• Abundant intellisense.
• Provides hooks into http-clients to set custom proxy settings etc.

What is the deal with the Versioning of ConsulSharp?

• This library is written for Hashicorp's Consul Service
• Hence this library makes it easier for its consumers to relate to the Consul service version it supports.
• Hence a ConsulSharp version of 1.2.x denotes that this library will support the Consul 1.2.x Service Apis for sure.
• Tomorrow when Consul Service gets upgraded to 1.4.x, this library will be modified accordingly and versioned as 1.4.x

Can I use it in my PowerShell Automation?

• Absolutely. ConsulSharp is a .NET Library.
• This means, apart from using it in your C#, VB.NET, J#.NET and any .NET application, you can use it in PowerShell automation as well.
• Load up the DLL in your PowerShell code and execute the methods. PowerShell can totally work with .NET Dlls.

All the methods are async. How do I use them synchronously?

• The methods are async as the defacto implementation. The recommended usage.
• However, there are innumerable scenarios where you would continue to want to use it synchronously.
• For all those cases, there are various options available to you.
• There is a lot of discussion around the right usage, avoiding deadlocks etc.
• This library allows you to set the 'continueAsyncTasksOnCapturedContext' option when you initialize the client.
• It is an optional parameter and defaults to 'false'
• Setting it to false, allows you to access the .Result property of the task with reduced/zero deadlock issues.
• There are other ways as well to invoke it synchronously, and I leave it to the users of the library. (Task.Run etc.)
• But please note that as much as possible, use it in an async manner.
