我尝试按照linux mint上的sqlprovider mysql provider的说明，使用monodevel或vs代码。我有：

let [<Literal>] connString = @"Server=localhost;Database=PriceData;User=root;Password=-----;SslMode=none"              
let [<Literal>] connexStringName = "DefaultConnectionString"            
let [<Literal>] dbVendor    = Common.DatabaseProviderTypes.MYSQL
let [<Literal>] resPath = __SOURCE_DIRECTORY__ + @"/../../../Simulations 2018-07-29/packages/MySqlConnector.0.43.0/lib/net45"
let [<Literal>] indivAmount = 1000
let [<Literal>] useOptTypes = true

和

type SQL = SqlDataProvider< dbVendor,
                            connString,
                            ResolutionPath = resPath,
                            IndividualsAmount = indivAmount,
                            UseOptionTypes = useOptTypes
                            Owner = "HR" >  ///"PriceData">

此类型声明出错：

The type provider 'FSharp.Data.Sql.SqlTypeProvider' reported an error: 
Invalid attempt to Read when reader is closed.

这件事让我完全困惑。我以前在windows和visualstudio中从未遇到过这样的错误。我找不到任何与f#和类型提供者相关的搜索。
谢谢你的建议。
