SQLite.SQLiteException: duplicate column name

[newtoncw]

I'm having the following error in my application, using Xamarin in Android: SQLite.SQLiteException: duplicate column name IdSettings.

Here is my code:

private Database()
{  
            this.connection = new SQLiteConnection(DatabasePath);

        this.Connection.CreateTable<Settings>();
        this.Connection.CreateTable<Profile>();
        this.Connection.CreateTable<Stat>();
        this.Connection.CreateTable<Crest>();
        this.Connection.CreateTable<MatchTeam>();
        this.Connection.CreateTable<Match>();
        this.Connection.CreateTable<Media>();
        this.Connection.CreateTable<DbInfo>();

}

And here is the stack trace from Android:

This occurs in the first run of the application, and I think that the method MigrateTable should not run.

[masterjs]

I'm also getting the same error with a very simple class

[newtoncw]

Problem solved!
In Android Options, I set linker to Sdk Assemblies Only.

[masterjs]

Thanks for the suggestion newtoncw, but setting Sdk Assemblies Only was not an option for us. So I instead went with a Execute that will do an explicit CREATE Table. This works well on all platforms.

[kyluke]

@masterjs how did you do that? Did you manually write out SQL queries?

[trevoriancox]

I am seeing this issue still. Link SDK assemblies only works for me too, so there must be something we need to preserve in the linking.

[trevoriancox]

This is still not a great solution but:

<AndroidLinkSkip>SQLite-net;SQLitePCL.raw</AndroidLinkSkip>

[praeclarum]

I will try adding the [Preserve] attribute to the assembly to help, but first I need to repro.
