title: Library to work with XAdES digital signatures
body: <p>I'm looking for a library compatible with microsoft.net framework that allows the creation and verification of XAdES signatures (XAdES, XAdES-C, XAdES-XL, etc...).</p>
  
  <p>It is important that the library enable the programmer to choose:</p>
  
  <p>1.- Type of certificate to use in the signature process (PFX file, Windows centralized store, SmartCard)<br/>
  2.- CRL to validate the certificate.<br/>
  3.- Possibility to include Time stamping on the signature.<br/>
  4.- Possibility to include OCSP response on the signature.<br/></p>
  
  <p>All I found are libraries in Java, but have not found any libraries in .NET.</p>
  
  <p>All suggestions are welcome.</p>
