Web deployment task failed

Question

I'm getting this error when I click Build Deployment Package. I've read a bunch of related post regarding this issue but doesn't seems to answer the questions on my mind T_T.

This is my connection string on my Web.Config

<connectionStrings>
    <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" />
    <add name="ProjectPALEntities" connectionString="metadata=res://*/Models.ProjectPal.csdl|res://*/Models.ProjectPal.ssdl|res://*/Models.ProjectPal.msl;provider=System.Data.SqlClient;provider connection string=';data source=.\SQLEXPRESS;attachdbfilename=|DataDirectory|\ProjectPAL.mdf;integrated security=True;user instance=True;multipleactiveresultsets=True;App=EntityFramework';" providerName="System.Data.EntityClient" />
  </connectionStrings>

This is Package/Publish SQL Settings Under Project Properties. This is where I'm having a problem.
This is the connection string for the source database above.

data source=.\SQLEXPRESS;attachdbfilename=|DataDirectory|\ProjectPAL.mdf;integrated security=True;user instance=True;multipleactiveresultsets=True;App=EntityFramework';

QUESTIONS:

• In the Connection string for the source database which is the correct one to use?

  data source=.\\SQLEXPRESS;attachdbfilename=|DataDirectory|\\ProjectPAL.mdf;integrated security=True;user instance=True;multipleactiveresultsets=True;App=EntityFramework'; ( this one is what I'm currently using )
  

  metadata=res:// /Models.ProjectPal.csdl|res:// /Models.ProjectPal.ssdl|res://*/Models.ProjectPal.msl;provider=System.Data.SqlClient;provider connection string=';data
  source=.\\SQLEXPRESS;attachdbfilename=|DataDirectory|\\ProjectPAL.mdf;integrated security=True;user
  instance=True;multipleactiveresultsets=True;App=EntityFramework'; ( with metadata or none of the above T_T )

• Where could I get the Connection string for destination database? Sorry It's my first time to deploy a website. I researched but I can't find an answer T_T.

• How could I possibly fixed this error?

Other Informations:

• I changed &quot with ' (single quote) after reading this reference Explicit connection string for EF

• I'm using Membership Provider and Role Provider and all my data is saved in ProjectPALEntities

If you need more Info just tell me. :)

Answer 1

Ok here's what I did.

I checkout new application from my repository and repeat every steps I did. When I click Import from web.config it automatically created this connection string for me under Connection string for source database .

Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ProjectPAL.mdf;Integrated Security=True;Application Name=EntityFramework;User Instance=True

for the Connection string for destination database I just leaved it blank because I dunno what to put there.

When I clicked Build Deployment Package the error message doesn't shows anymore.
I wish I knew what to put ont the Connection string for destination database T_T
