“Unable to emit assembly: Referenced assembly 'Microsoft.Practices.EnterpriseLibrary.Data”

Question

Hi,

 

 I created a class library named ccard which uses enterprise library for database access.

I tested it with the website it is working fine.

Our requirement is to use this  as .net com (dll) and refer it in  an asp application.

Here comes the problem for me.

This needs all the dlls to be strong named.

So I signed the ccard library using snk tool and complied (build).

It is throwing below error”

 

“Unable to emit assembly: Referenced assembly 'Microsoft.Practices.EnterpriseLibrary.Data”

 

So I tried to strong name the enterprise library -  'Microsoft.Practices.EnterpriseLibrary.Data and also other dlls present in the solution . but it doesn’t work it out.

 

So referred some websites to string the 'Microsoft.Practices.EnterpriseLibrary.Data”

 It is also not working out.

 

Please help me out. It is a top priority work for me.

Please help me how to strong name the Enterprise Library dlls and usage of it in our own class library.

 

Thanks in advance

Answer 1

Did you try to use the 'Strong Naming Guidance Package' that is shipped with the ETL?

If not, open the project('Strong Naming Guidance Package') which is situated in the ETL directory and compile/build it. after that run the msi/exe created after building it.

 my scenario was that i got a project with 11 class libraries in that, and one webservice project , what happened when i took get latest, i got same error not loading an assemblies of microsoft enterprise library,

i installed Microsoft enterprise library and reference to project where i need to add dll , i.e. Microsoft.Practices.EnterpriseLibrary.Common. but when i add reference i was still getting this erorr. i recycle the iis pool but that didnt work.

solution : remove all the reference dll from the web service application and compile and also update the public token key in your web config to your all enterprise library referencing dll.
