C# – Best way for Flex to communicate with C# backend

apache-flexchttpprotocolssoap

What is the best way for flex frontend to communicate with backend writted in C#? The only communication channel in HTTP, so no custom sockets.

I used SOAP in the past, but am concerned about performance since the large overhead of xml, and this application I'm currently working on will be pretty data intensive.

Anything that supports easy setup and transparent marshaling/unmarshaling is OK.

Is there something as BlazeDS for .net?

Best Answer

I found a few options by googling AMF .NET and AMF C# (AMF is the protocol that BlazeDS uses)-

WebOrb for .NET (commercial)
FlourineFX (open source)
AMF.NET (open source - appears to be dead)

However, I haven't used any of these projects - I've just used Flex backed by Java and PHP.

C# – the best way to give a C# auto-property an initial value

In C# 5 and earlier, to give auto implemented properties an initial value, you have to do it in a constructor.

Since C# 6.0, you can specify initial value in-line. The syntax is:

public int X { get; set; } = x; // C# 6 or higher

DefaultValueAttribute is intended to be used by the VS designer (or any other consumer) to specify a default value, not an initial value. (Even if in designed object, initial value is the default value).

At compile time DefaultValueAttribute will not impact the generated IL and it will not be read to initialize the property to that value (see DefaultValue attribute is not working with my Auto Property).

Example of attributes that impact the IL are ThreadStaticAttribute, CallerMemberNameAttribute, ...
