## Instances are single-use

A <xref:System.Security.Cryptography.Xml.SignedXml> instance is not intended to be reused across multiple signing or verification operations. Starting in .NET 12, calling <xref:System.Security.Cryptography.Xml.SignedXml.ComputeSignature*> or <xref:System.Security.Cryptography.Xml.SignedXml.CheckSignature*> more than once on the same instance, or calling <xref:System.Security.Cryptography.Xml.SignedXml.LoadXml*>, <xref:System.Security.Cryptography.Xml.SignedXml.AddReference*>, or <xref:System.Security.Cryptography.Xml.SignedXml.AddObject*> after a call to <xref:System.Security.Cryptography.Xml.SignedXml.ComputeSignature*> or <xref:System.Security.Cryptography.Xml.SignedXml.CheckSignature*> has begun on the same instance, throws <xref:System.InvalidOperationException>. This applies even if the earlier call itself threw an exception. Create a new <xref:System.Security.Cryptography.Xml.SignedXml> instance for each signing or verification operation.
