与.NET应用程序一起部署SQLite时的清单

Question

I need to deploy SQLite file with WPF application.

• Deployment technique is ClickOnce .
• Entity Framework is included to work with the database.

I'd like to have a shortlist what must be considered when deploying the application that includes a SQLite database file in it.

So far, I have referenced and set Copy Local to True for:

• System.Data.SQLite
• System.Data.SQLite.Linq

.and I have two interops where Copy to Output Directory I left to be the default Copy Always

• SQLite.Interop.dll (x86)
• SQLite.Interop.dll (x64)

In the app.config file I have:

<applicationSettings>
    <MyApp.MySettings>
       <setting name="connStrSQLite" serializeAs="String">
           <value>data source="C:\MyFolder\MySQLiteFile.sqlite3"</value>
       </setting>
    </MyApp.MySettings>
</applicationSettings>

and

<connectionStrings>
    <add name="MyEntities" connectionString="metadata=res://*/Model.ORM.MyModel.csdl|res://*/Model.ORM.MyModel.ssdl|res://*/Model.ORM.MyModel.msl;provider=System.Data.SQLite;provider connection string='data source=&quot;C:\MyFolder\MySQLiteFile.sqlite3&quot;'" providerName="System.Data.EntityClient" />
</connectionStrings>

I suppose in the app.config the paths are not working on deployed application since they are referring to my local folder now. How to modify them ?

Then, I checked for example from here SQLite deployment for .net application that the following should be added to app.config file.

<system.data>
    <DbProviderFactories>
      <remove invariant="System.Data.SQLite" />
      <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" />
    </DbProviderFactories>
</system.data>

Anything else?

regarding your connection string - for ClickOnce installation you should use |DataDirectory| substitution instead of full path - runtime will automatically convert this into proper local path:

<connectionStrings>
    <add name="MyContext" connectionString="DataSource=|DataDirectory|Mydb.sdf" providerName="System.Data.SqlServerCe.4.0"/>
  </connectionStrings>
