Simple csharp with SHA256CryptoServiceProvider

[pengzeshan]

I have a simple csharp code related to SHA256CryptoServiceProvider. Here is a simple example csharp code: using System; using System.Security.Cryptography; namespace ConsoleApp1 { class Program { static void Main(string[] args) { Console.WriteLine("Hello World!"); var ha = new SHA256CryptoServiceProvider(); Console.WriteLine("hello again"); } } }

Error message: Severity Code Description Project File Line Suppression State Error MSB4018 The "Translate" task failed unexpectedly.

Here is the IL2C.Build version used to trigger the above error:

@pengzeshan Sorry delay, unfortunately SHA256CryptoServiceProvider implementation doesn't port into IL2C. I think if I port it:

• Pure sha256 native code (by C lang) links into your app (with ld option).
• Write bridge code fragment by IL2C/Invoke semanrics or P/Invoke's.
  • Caution: P/Invoke support is very experimental stage and lack a lot of features, so I recommend using IL2C/Invoke.

If you want to get more IL2C/Invoke information, I recommend referring my blog entry Try writing code using both the Azure Sphere Development Kit and C#

• IL2C already dropped Azure Sphere environment (Reason), but I think fill and understand this feature.
• It's bit older, very poor English :)
