Gets the size of the current key.
Assembly: mscorlib.Extensions (in mscorlib.Extensions.dll)
In Silverlight for Windows Phone, the RSACryptoServiceProvider supports key lengths from 384 bits to 4800 bits in increments of 8 bits.
The RSACryptoServiceProvider class does not allow you to change key sizes using the property. Any value written to this property will fail to update the property without error. To change the key size, use one of the constructor overloads.
For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.
