Strong name signature not valid for this assembly Microsoft.Practices.EnterpriseLibrary.Data.dll

问题

I am running windows form application as ClickOnce Deployment. When i debugg the solution i am not getting any error. it's working fine. But, when i publish the application using click once deployment and run the application from folder, i am getting the following error log. Can anyone help me out what exactly the problem is?

     The Dll's are in assemblies folder in one of the project.And they are used in other project as reference.

回答1:

I faced the same issue when I did click once deployment. The possible errors are the property settings are wrong. 1.Did u strong name this assembly?. After strong naming did you delete the old reference and add a new one ? If so that's wrong. We need not explicitly add the dll again. Once we build it ll get referred automatically. If you have removed the reference added explicitly then check the below condition, 1.a Go to project properties -> publish -> Application Files -> Check if there is any reference to this particular DLL other than GAC reference(by default this DLL would be reffered to DLL from GAC, when u explicitly add reference from your machine then the local references will also get added) -> If u find any such thing just exclude it build it again and trigger a new click once build -> the problem should be solved.

2. And for the reference set CopyLocal property to true. References -> Select the corresponding DLL -> Set copyLocal property to true.
