Extending .NET 2.0 class library for WCF use -

-

we publish class library must remain compatible .net 2.0. however, use class library internally wcf-based projects.

reading e.g. expose-object-from-class-library-using-wcf brings approach using 2.0 class libraries creating datacontractsurrogate objects map 2.0 classes. however, our object hierarchy rich , deep, , tedious , difficult maintain.

since control source code, i'm looking easier approach.

one thought add dataconract attribute source code, , provide "empty" implementation of datacontractattribute when solution built targeting 2.0 runtime, , using system.runtime.serialization implementation when solution built targeting 3.0 , newer runtimes. accomplished manually tweaking references between builds.

is there better way implement approach?

is there better approach?

an alternative approach add wcf attributes (datacontractattribute etc), , build .net 3.0 assemblies.

when run application under .net 2.0, having attributes assembly not available @ runtime won't cause problem.

(you error if try access attributes, unlikely , easy avoid).

c++ - Convert big endian to little endian when reading from a binary file -

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

C#: Application without a window or taskbar item (background app) that can still use Console.WriteLine() -

-
i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() . (i.e. if executes app command prompt write console.) the problem if create windows form (or wpf) application can have there no taskbar, console or window show up, console.writeline() nothing. if create console app, writes console, can't figure out how hide (and if did hide it, write command prompt window?)... how do this? just create standard console application. callers responsibility hide window caused program (from how run c# console application console hidden ): system.diagnostics.processstartinfo start = new system.diagnostics.processstartinfo(); start.filename = dir + @"\myprocesstostart.exe"; start.windowstyle = system.diagnostics.processwindowstyle.hidden;
