Dear Jayaprakash

I think without appname.exe.config. also we can build the forms. According to my knowledge this file is not mondatory to be explicitly invoke then how can we say one application is developed in .net compatible languge. In other words how can we say the application is developed in Managed way and not is UnManaged way. So Please clarify me in this regard.

I would try to decompile the exe using the ildasm.exe. If a CLR header is found the manifest should give the details regarding the application.

try this code

using System;

using System.Collections.Generic;

using System.Text;

using System.Reflection;

namespace checkingnetproj

{

class Program

static void Main(string[] args)

{

string FullPATHofFile;

FullPATHofFile <path of the exe or dll> ;

try

{

AssemblyName assemblyName AssemblyName.GetAssemblyName(FullPATHofFile);

Console.WriteLine( {0} - is a .NET assmbly. FullPATHofFile);

}

catch (BadImageFormatException)

{

Console.WriteLine( {0} - Not .NET assmbly. FullPATHofFile);

}

Console.ReadLine();

}

}

This will help u.

Every exe is in PE(Portable executable ) form which keeps the information about in which environment it is to be run so if try to run any exe that is not .NET complaint it will not run.

There are two easy methods
1) No programming:
Load the EXE/DLL with ILDASM.exe if it is .Net programed than it will work otherwise it will throw error.
2) Programatically:
Use reflection API to LoadAssembly. It it is not a .Net program it will throw exception.
