I am using mono on Linux, making an F# code to access an SQL Server Database. I am using SqlDataConnection.
My code is the following:
namespace AggregatorService
open FSharp.Data.TypeProviders
open System.Data
open System.Data.Linq
module DataBaseProvider =
type databaseConn = SqlDataConnection<ConnectionString = "Data Source=10.0.40.11;Initial Catalog=master;Persist Security Info=True;User ID=sa;Password=xxxxx">
let getDataContext() =
let dbConn = databaseConn.GetDataContext();
dbConn
I can't compile this code. I am getting this annoying error:
The type provider 'FSharp.Data.TypeProvider.DesignTime.DataProviders' reported an error reading schema. No access to the given key (FIS3033)
My package.config file is:
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="Deedle" version="1.2.5" targetFramework="net40" />
<package id="FSharp.Core" version="4.0.0.1" targetFramework="net40" />
<package id="FSharp.Data" version="2.3.2" targetFramework="net40" />
<package id="FSharp.Data.SqlClient" version="1.8.2" targetFramework="net40" />
<package id="FSharp.Data.TypeProviders" version="5.0.0.2" targetFramework="net40" />
<package id="NUnit" version="2.6.4" targetFramework="net40" />
<package id="SQLProvider" version="1.0.22" targetFramework="net40" />
</packages>
A C# program is connecting from the same computer, so, I think the problem is not with mono configurations or to be in a Linux machine.
Anyone has a solution or a Tip on how to solve that?
Unfortunatelly it looks mono is not able to deal this package as well I wish. Searching I found there is a bug from two years ago, but I don't find any solution yet.
What I am doing to leave that is using FSharp.Data.Sql instead, then, I use SqlDataProvider instead of SqlDataConnection, ow it looks:
namespace AggregatorService
open FSharp.Data.Sql
open Deedle
open System.Linq
module DatabaseService =
[<Literal>]
let connectionString = "Data Source=10.0.40.11;Initial Catalog=nextel_ericsson_umts_brasil;Persist Security Info=True;User ID=sa;Password=****";
type bd = SqlDataProvider<
ConnectionString = connectionString,
DatabaseVendor = Common.DatabaseProviderTypes.MSSQLSERVER >
type Database() =
static member contextDbo() =
bd.GetDataContext().Dbo
static member acAgregations() =
Database.contextDbo().AcAgregations |> Frame.ofRecords
static member acBusyHourDefinition() =
Database.contextDbo().AcBusyHourDefinition
|> Frame.ofRecords
//|> Frame.getCols["time_agregation_type", "destination_table", "reference_table", "alternative_reference_table_scan", "formula"]
static member acBusyHourDefinitionFilterByTimeAgregationTipe(value:int) =
Database.acBusyHourDefinition()
|> Frame.indexRowsInt "tome_agregation_type"
|> Frame.getRows
|> Frame.filterRowValues( fun row -> row.GetAs<string list>)
As I can see, that works the same way. I don't know if there is some difference expected, but it's dealing with my needs until now.

I am specifying <appSettings> in my app.config file, I am adding
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings configSource="ShareAppSettings.debug.config"/>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.1"/>
</startup>
</configuration>
ShareAppSettigns.debug.config is my external config file, which I am using on my local machine and I do not want to share it with the rest of my team.
ShareAppSettings.debug.config looks like:
<?xml version="1.0" encoding="utf-8" ?>
<appSettings>
<add key="clientID" value="11" />
<add key="clientSecret" value="11" />
<add key="tenantID" value="11" />
</appSettings>
Whenever I am trying to debug the main code:
private static List<string> AppCredentials()
{
string clientID = ConfigurationManager.AppSettings["clientID"];
string clientSecret = ConfigurationManager.AppSettings["clientSecret"];
string tenantID = ConfigurationManager.AppSettings["tenantID"];
List<string> appCred = new List<string> { clientID, clientSecret, tenantID };
if (clientID == null)
throw new Exception("ShareAppSettings.Debug.Config file was not provided in this repo.");
return (appCred);
}
For some reason I am not getting values for clientId, slientSecret nor tenantId. This code is a part of grasshopper Add-on for v6 template, and its running on .NET Framework 4.7.1. Whenever I copy the same code into a new C# console of a same framework, the code is built. I would truly appreciate if you could give me suggestions on how to solve this.
What "EnableWindowsFormsHighDpiAutoResizing" means and how can make this work?
Many Thanks

I suggest to use the file attribute (corresponding to the AppSettingsSection.File property) instead of the configSource attribute (corresponding to the SectionInformation.ConfigSource property) in the appSettings section.
configSource doesn't support other keys in the section, while appSettings may contain other keys, needed by the Application and possibly somewhere else (someone else may add/remove them - for testing purposes or any other reason).
The file attribute allows instead the presence of other key in the appSettings section.
Your app.config file can be:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings file="ShareAppSettings.debug.config">
<add key="DpiAwareness" value="PerMonitorV2"/>
</appSettings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.1"/>
</startup>
</configuration>
Now the values are accessible by both opening a named configuration section:
appSettings.Settings[] returns a KeyValueConfigurationElement
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
AppSettingsSection appSettings = (AppSettingsSection)config.GetSection("appSettings");
var kvpClientID = appSettings.Settings["clientID"];
var kvpClientSecret = appSettings.Settings["clientSecret"];
var kvpCenantID = appSettings.Settings["tenantID"];
string clientID = kvpClientID.Value;
and directly, using ConfigurationManager.AppSettings - a NameValueCollection - which returns the value of the specified key:
string clientID = ConfigurationManager.AppSettings["clientID"];
string clientSecret = ConfigurationManager.AppSettings["clientSecret"];
string tenantID = ConfigurationManager.AppSettings["tenantID"];
As a note, using the file attribute, your ShareAppSettings.debug.config doesn't need (but it's not forbidden) the XML header, it can be just:
<appSettings>
<add key="clientID" value="11" />
<add key="clientSecret" value="11" />
<add key="tenantID" value="11" />
</appSettings>
Secondary note:
you can set the file attribute to point to another file at run-time and refresh the appSettings values to updated the configuration.
Note that, if a file attribute was already set, all values contained in that .config file are not dismissed, but instead moved to the [Application].exe.config file, to become part of the <appSettings> section (thus, they are preserved).
Another reason why using the file attribute may be preferable.
var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var appSettings = config.AppSettings;
appSettings.File = "SomeOtherFile.config";
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");
In a very simple Silverlight Application I have a DomainService Class which has a single method that returns a list of Letter Objects.
The application works fine when I run it in VisualStudio. However, when I publish it to a folder on my Windows 10 local machine and run it using IIS (version 10.0.166299.5) I get the following error:
The remote server returned an error: NotFound.
at System.ServiceModel.DomainServices.Client.OperationBase.Complete(Exception error) at System.ServiceModel.DomainServices.Client.LoadOperation.Complete(Exception error) at System.ServiceModel.DomainServices.Client.DomainContext.CompleteLoad(IAsyncResult asyncResult) at System.ServiceModel.DomainServices.Client.DomainContext.<>c__DisplayClass1b.b__17(Object )
I supect this is due to something being wrong in missing in my WebConfig file. My WebConfig Currently looks like this:
<?xml version="1.0"?>

The error was due to the problem that .svc file wasn't being served.. The problem got solved with the kind help from the Kyle Abraham on Experts Exchange.
https://www.experts-exchange.com/questions/29084691/RIA-Service-Error-in-a-Silverlight-Application.html
The solution was to add the following line to the webserver section of the Webconfig
<handlers>
<add name=".svc" verb="*" path="*.svc" type="System.ServiceModel.Activation.ServiceHttpHandlerFactory, System.ServiceModel.Activation, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</handlers>
I'm not sure, its a guess as I have not used RIA for awhile, but I think letters needs to returned as something other than queryable... try ToList() which causes the query to execute, and the payload is complete with the complete enumeration that was retrieved from the database. Remember, this is a remote call from a client, not a local one that can extend the queryable.
I know this question may be ridiculous but I could not find the answer. The Post sharp writes the logs in console by System.Diagnostics but I need to write the logs in a separate file. Is there any way to do so?
Thanks in advance
I found also I can do this in the app.config as the following:
<system.diagnostics>
<trace autoflush="true" indentsize="4">
<listeners>
<add name="myListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="C:\\log.txt" />
<remove name="Default" />
</listeners>
</trace>
</system.diagnostics>
You need to use System.Diagnostics.Trace.Listeners property to register your own listener. You would need code like this in your app's entry point:
using (StreamWriter sw = new StreamWriter("file.txt"))
using (TextWriterTraceListener tl = new TextWriterTraceListener(sw))
{
Trace.Listeners.Add(tl);
try
{
// execute your program here
}
finally
{
Trace.Listeners.Remove(tl);
}
}
I have an app.config file that stores values in a few different sections. I have these snippets:
<configuration>
<configSections>
<sectionGroup name="someDataAccessLayer">
<section name="databaseConnectionStrings" type="sometype" />
</sectionGroup>
</configSections>
<someDataAccessLayer>
<databaseConnectionStrings>
<databaseConnectionString name="someSQL"
value="database=somedatabase;Integrated Security=False;User Id=sa;server=someserver;Password=somepassword/>
</databaseConnectionStrings>
</someDataAccessLayer>
How do I read the connection string in the codebehind? Specifically the value which is
database=somedatabase;Integrated Security=False;User Id=sa;server=someserver;Password=somepassword
Thanks for your help! Please let me know if the question is still unclear.
Your configuration section will be associated with some .NET class to handle it:
<configSections>
<sectionGroup name="someDataAccessLayer">
<section name="databaseConnectionStrings" type="sometype" />
</sectionGroup>
</configSections>
So to read the settings from the <localeSettings> section, you need to use the ConfigurationManager (add a reference to System.Configuration to your project) to get those settings into an instance of that class:
sometype cs = ConfigurationManager.GetSection("someDataAccessLayer/databaseConnectionStrings") as sometype;
Now you have an object of type sometype that contains all the settings in that config section. One of those properties will be a list of database connection strings, which you can now enumerate and find the appropriate one and read it's .Value property.
App.Config Settings:
<configuration>
<configSections>
</configSections>
<connectionStrings>
<add name="MyApp.LocalConnectionString"
connectionString="Data Source= .\SQLEXPRESS;Initial Catalog=DBName;Integrated Security = true"
providerName="System.Data.SqlClient" />
Access at DataLayer using the ConfigurationManager as:
// add reference
using System.Configuration;
// then access connection string in your class
private static string strConnectionString = ConfigurationManager.ConnectionStrings["MyApp.LocalConnectionString"].ConnectionString;
i would like to set up an external configuration file that I can store in a directory for my WPF app, not necessarily the directory of my exe when I create my program either.
I created an App.Config file and added System.Configuration to my assembly. My App.Config has:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings file="sd.config">
<add key="username" value="joesmith" />
</appSettings>
</configuration>
and my sd.config (external file) which is in the root of my project for now, has
<?xml version="1.0"?>
<appSettings>
<add key="username1" value="janedoe" />
</appSettings>
in my MainWindow cs class I used
string username = ConfigurationManager.AppSettings.Get("username1");
which returns a null string. when i just retrieve the username field from App.Config it works. What did i miss? Thanks so much!
See the documentation on ConfigurationManager:
The AppSettings property:
Gets the AppSettingsSection data for the current application's default
configuration.
You need to do a little extra work to get data that isn't in your application's default configuration file.
Instead of using the file= attribute, add a key to your <appSettings> that defines the location of the secondary config file, like so:
<add key="configFile" value="sd.config"/>
Then, in order to use ConfigurationManager to pull settings from the secondary config file, you need to use its OpenMappedExeConfiguration method, which should look a little something like this:
var map = new ExeConfigurationFileMap();
map.ExeConfigFilename = Path.Combine(
AppDomain.CurrentDomain.SetupInformation.ApplicationBase,
ConfigurationManager.AppSettings["configFile"]
);
//Once you have a Configuration reference to the secondary config file,
//you can access its appSettings collection:
var config = ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None);
var userName1 = config.AppSettings["username1"];
That code might not be dead-on for your example, but hopefully it gets you on the right track!
