if i sign using this .NET code and try to verify using GO CODE its not working it says tags don't match (16 vs {class:3 tag:1 length:39 isCompound:false}) {optional:false explicit:false application:false private:false defaultValue:<nil> tag:<nil> stringType:0 timeType:0 set:false omitEmpty:false} @2.

but if if i sign with SIGNER and try to VERIFIER with this is also working.

i want to make .NET comparable with VERIFIER.
and if i try to verify with VERIFIER2 this go code its working good.

i want to use VERIFIER dont want to change code on verification part. C# can be changed.
