C# Interactive

-
Think...

You have a solution with multiple C# projects and include maybe 1000 classes which are so hard to debug and test. But you have a task to validate the output of certain functions when certain parameters have specific values assigned. Especially, you don't have unit tests added or difficult to implement unit tests. 

Idea...

You can use C# Interactive to cater to everything above and there are many benefits. C# Interactive is a feature that comes with Visual Studio 2015 update 1 and later versions. It is a REPL Editor for C# (Read-Evaluate-Print-Loop). If you are interested in learning how to code you can use the online version of this C# Interactive to write and execute codes. 

You can use Microsoft's C# learning site if you don't have Visual Studio installed on your PC. 

If you have Visual Studio installed in your machine you can go to View > Other Windows > C# Interactive to open the C# Interactive window.


If you want to execute any method in C# Interactive windows you can right-click on the function you want to run and select Execute in Interactive option which will add the selected method on to the Interactive windows automatically. 


You can use Console.WriteLine() method to print the output of the method that you wanted to validate.


Interestingly C# Interactive supports Intelligence so that you can easily write your code.


It supports Compile-time and Runtime errors as well which again helps to write and test the code right. 

Moreover, if you need to run any method and test any method in a DLL you can load and execute the methods as you intended. To load DLLs you can use "#r" operator with the path of the dll to be load. 

 

Additionally, you can use C# Interactive on Visual Studio Developer command prompt as well. You just open the VS Developer command prompt and type "csi" and hit enter.


Hope this will help you to speed up your coding. 
Cheers!!

Dependency Injection for Azure Function

-
Enabling dependency injection on your Azure Function a little bit different than the usual process like you do on the .Net Core applications. Here I'm planning to share some tips and steps you should follow if you need to enable DI on Azure Functions with C#. I'm focusing on a function application created for HTTP Trigger. When you create a new project you will see a static class and method to run your function end-point.  1 2 3 4 5 6 7 8 9 10 11 public static class FunctionWithDI { [FunctionName("function-with-di")] public static async Task<IActionResult> Run( [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req, ILogger log) { log.LogInformation( "C# HTTP trigger function processed

Azure Cloud Service is one of the very useful PAAS (Platform-As-A-Service) offerings that Azure provides to deploy your Worker Role or Web Role into the cloud VM(s). So you can control the scalability, reliability, and cost anticipated for your application.  You can access your service remotely if you expose your Web Role endpoints. However, this post is about how you enable remote desktop access to your cloud service VM(s) secured manner.  There are two ways of enabling the Remote Desktop feature on your cloud service. - Azure Portal configuration (UI) - Cloud Definition and Configuration (code deployment) This is the link to enable RDP using the Azure Portal . Here in this post, we are more focused on how to enable RDP from the code. Pre-requisites: - Azure SDK - Azure Portal Access - Cloud Service Solution for testing  Steps: Open your cloud solution and locate the below files - ServiceConfiguration.cscfg  - ServiceDefinition.csdef In your ServiceDefinition file, you need to defi
