Deployment without installing to Windows server

Post by meysam57 » Wed 13 Nov 2019 10:34

First of all, If we have to install dotConnect to the windows server we will, but the goal is to be able to do our deployments without having to worry about installing dotConnect package to the windows server.
  • I have the 3 DLLs(Devart.Data,Devart.Data.Oracle,Devart.Data.Oracle.Entity.EF6)
  • Set the 3 DLLs to "Copy Local" (so that they copy to the BIN directory output on build)
  • Success Generate a License file using the License Generation Wizard
  • web config:
    <compilation debug="true" targetFramework="4.5">
    <assemblies>
    <add assembly="Devart.Data, Version=5.0.2158.0, Culture=neutral, PublicKeyToken=09AF7300EEC23701"/>
    <add assembly="Devart.Data.Oracle, Version=9.7.734.0, Culture=neutral, PublicKeyToken=09AF7300EEC23701"/>
    </assemblies>
    </compilation>

    <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
    <providers>
    <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    <provider invariantName="Devart.Data.Oracle" type="Devart.Data.Oracle.Entity.OracleEntityProviderServices, Devart.Data.Oracle.Entity.EF6, Version=9.7.734.0, Culture=neutral, PublicKeyToken=09AF7300EEC23701" />
    </providers>
    </entityFramework>

    <system.data>
    <DbProviderFactories>
    <remove invariant="Devart.Data.Oracle" />
    <add name="dotConnect for Oracle" invariant="Devart.Data.Oracle" description="Devart dotConnect for Oracle" type="Devart.Data.Oracle.OracleProviderFactory, Devart.Data.Oracle, Culture=neutral, PublicKeyToken=09AF7300EEC23701" />
    </DbProviderFactories>
    </system.data>

but an error when executing my website
Could not load file or assembly 'Devart.Data.Oracle' or one of its dependencies. Strong name signature could not be verified.


Any help?

Please add the version to the DbProviderFactories registration:

Code: Select all

<system.data>
  <DbProviderFactories>
    <remove invariant="Devart.Data.Oracle" />
    <add name="dotConnect for Oracle" invariant="Devart.Data.Oracle" description="Devart dotConnect for Oracle" type="Devart.Data.Oracle.OracleProviderFactory, Devart.Data.Oracle, Version=9.7.734.0, Culture=neutral, PublicKeyToken=09af7300eec23701" />
  </DbProviderFactories>
</system.data>

1. Try using original lower case in all Devart entries of your web.config:
PublicKeyToken=09AF7300EEC23701
->
PublicKeyToken=09af7300eec23701

2. Confirm that .NET Framework 4.5 is installed on your deployment server.

3. Specify the full stack trace of the exception.

Re: Deployment without installing to Windows server

Post by Shalex » Thu 28 Nov 2019 16:58

1. Your website works OK in the development environment with the installed provider, but fails on the deployment server without installed provider. Is this correct?

2. With sn.exe shipped with .NET Framework SDK on the deployment server, make sure that it verifies Devart.Data.dll, Devart.Data.Oracle.dll, Devart.Data.Oracle.EF6.dll successfully.

3. Try adding the following entries to web.config:

Code: Select all

<system.web>  
  <compilation  targetFramework="4.5">  
    <assemblies>
      <add assembly="Devart.Data, Version=5.0.2158.0, Culture=neutral, PublicKeyToken=09af7300eec23701"/>
      <add assembly="Devart.Data.Oracle, Version=9.7.734.0, Culture=neutral, PublicKeyToken=09af7300eec23701"/>
      <add assembly="Devart.Data.Oracle.Entity.EF6, Version=9.7.734.0, Culture=neutral, PublicKeyToken=09af7300eec23701"/>
    </assemblies>  
  </compilation>   
</system.web>
4. Clear the folders in the deployment:
* C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\
• C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files\
• C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\
• C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\
• C:\Users\YOUR_OS_USER\AppData\Local\Temp\Temporary ASP.NET Files\
Does this help?

5. Send us a small test project so that we can reproduce the issue in our test environment.
