Optimization option in C# and VB .NET compilers.

Hello,

Could you please provide additional information about optimize option (https://msdn.microsoft.com/en-us/library/t0hfscdc.aspx and https://msdn.microsoft.com/en-us/library/yf8493s5.aspx)?

1) What is the main difference between optimize and not optimize assemblies?

1) Against what environment .NET compiler is optimizing?

2) We are still using COM+ & ADODB technologies in .NET code, how this option effects on this?

3) Are there any difference of optimize option between C# compiler and VB .NET compiler?

Thanks.
