Tips & Tricks:

Please add some!

Sample Code:

class CoreDllWrapper
{
    [DllImport("coredll.dll", SetLastError = true)]
     public static extern int GetModuleFileName(IntPtr hModule, StringBuilder lpFilename, int nSize);
}

// Will write the current executable's complete path into exePath
StringBuilder exePath = new StringBuilder(1024);
int exePathLen = CoreDllWrapper.GetModuleFileName(IntPtr.Zero, exePath, exePath.Capacity);
