We are using following code to convert CMYK image to RGB mode :

Code:
Aurigma.GraphicsMill.Bitmap BKG_CMYK = new Aurigma.GraphicsMill.Bitmap();

BKG_CMYK.ColorManagement.ColorManagementEnabled = true;
BKG_CMYK.Load(@"C:\Documents and Settings\ngarg\Desktop\CMYK.jpg");

BKG_CMYK.ColorProfile = new Aurigma.GraphicsMill.ColorProfile(@"c\kashcard\kc\Profiles\USWebCoatedSWOP.icc");
BKG_CMYK.ColorManagement.RgbColorProfile = new Aurigma.GraphicsMill.ColorProfile(@"c:\My Project\kashcard\kc\Profiles\sRGB Color Space Profile.icm");
BKG_CMYK.ColorManagement.CmykColorProfile = new Aurigma.GraphicsMill.ColorProfile(@"c:\My Project\kashcard\kc\Profiles\USWebCoatedSWOP.icc");
BKG_CMYK.ColorManagement.TargetColorProfile = new Aurigma.GraphicsMill.ColorProfile(@"c:\My Project\kashcard\kc\Profiles\USWebCoatedSWOP.icc");

BKG_CMYK.ColorManagement.ConvertToContinuous(Aurigma.GraphicsMill.ColorSpace.Rgb, true, BKG_CMYK.IsExtended);

BKG_CMYK.Save(@"C:\Documents and Settings\ngarg\Desktop\finalCMYK(Aurigma).jpg", new Aurigma.GraphicsMill.Codecs.JpegEncoderOptions());
pictureBox2.ImageLocation = @"C:\Documents and Settings\ngarg\Desktop\finalCMYK(Aurigma).jpg";
BKG_CMYK.Dispose();

but the color of output image is not similar to image saved using Photoshop application for conversion CMYK to RGB mode with same profile.

for reference find attached files.

It is very urgent, Please reply as soon as possible.

Thanks & Regards

Hello,

To duplicate your issue we need for source and destination color profiles. Could you send it by email?

Sincerely yours,

Hello,

I have replied by email. It seems that the problem is in Microsoft ICM, use Adobe ICM in Photoshop.

Sincerely yours,

Dmitry Sevostyanov
