I can't seem to get the SqlProgrammabilityProvider to work even in the most basic configuration. With this code
type TestDb = SqlProgrammabilityProvider<testConn>
let db = TestDb()
I get the design/compile-time error "The value or constructor 'TestDb' is not defined"
testConn is a literal string that is working fine with the SqlCommandProvider in the same project.
I'm using VS 2015, FSharp.Data.SqlClient 1.7.5, and I've tried targeting .NET 4.5.2 and 4.6.
Are there known issues or limitations with this? If not, how could I troubleshoot it?
After getting a type for SqlProgrammabilityProvider upon a specific connection you should tie it to as many as you like, but of the concrete following options: Sql Server function, stored procedure, or table.
Like in:
type TestDb = SqlProgrammabilityProvider<testConn>
type Datatable = TestDb.dbo.Tables.MyDataTable
or
use cmd = TestDB.dbo.MyStoredProcedure()
cmd.Execute(Param1="xyzzy")
You may peek at use cases at https://github.com/fsprojects/FSharp.Data.SqlClient/tree/master/src/SqlClient.Tests

I am writing a service using .net Core with Visual Studio 2017. I want to use JSON for the configuration, so I defined my type like this:
type ServiceConfig = JsonProvider<"exampleConfig.json", EmbeddedResource="MyService, exampleConfig.json", SampleIsList = true>
In my program, I load it like this:
let conf = ServiceConfig.Load "config.json"
When I run it, it works fine, but in VS 2017 I get a red squiggly line and the error log says:
FS3033 The type provider 'ProviderImplementation.JsonProvider'
reported an error in the context of provided type
'FSharp.Data.JsonProvider,Sample="exampleConfig.json",SampleIsList="True",EmbeddedResource="MyService, exampleConfig.json"', member 'Load'. The error: Method
'FSharp.Data.Runtime.BaseTypes.IJsonDocument
Create(System.IO.TextReader, System.String)' not found in type
''. This method may be missing in the types available in the
target assemblies.
How do I get rid of this?
I'm not sure that this is the problem, but it might help to give an absolute path of the sample file. Resolving a relative path is a constant source of issues in type providers. You can do something like:
[<Literal>]
let sample = __SOURCE_DIRECTORY__ + "/exampleConfig.json"
type ServiceConfig =
JsonProvider< sample, EmbeddedResource="MyService, e
xampleConfig.json", SampleIsList = true >
By chance I found the answer myself. It must have been some Visual Studio index having gone wonky. I had another problem with another project in my solution so I just did an "emergency commit" to git, cleaned my local working copy using git clean -fdx and then reloaded the solution, rebuilt everything and the errors went away.
I just moved a function from an MVC App to an MVC API App, and for some reason it all works except CloudTable.Execute.
Code:
try
{
CloudStorageAccount storageAccount = new CloudStorageAccount(new Microsoft.WindowsAzure.Storage.Auth.StorageCredentials(
"accountName",
"key"), true);
CloudTableClient cloudTableClient = storageAccount.CreateCloudTableClient();
CloudTable table = cloudTableClient.GetTableReference("SkypeUsers");
table.CreateIfNotExistsAsync();
TableOperation retrieveOperation = TableOperation.Retrieve<WorkUser>("Skype", skypeid);
TableResult retrievedResult = table.Execute(retrieveOperation); //Does not work
retrievedSkypeId = ((WorkUser)retrievedResult.Result).RowKey;
}
catch (Exception ex)
{
}
Error:
Error CS1061 'CloudTable' does not contain a definition for 'Execute' and no
extension method 'Execute' accepting a first argument of type 'CloudTable' could
be found (are you missing a using directive or an assembly reference?)
The reference to Microsoft.WindowsAzure.Storage is the same version I use in my App. Ive tried cleaning and re-building. Not sure what the issue is.
EDIT:
Print of my only Execute-options:
I am targeting .NET Core & using assembly Microsoft.WindowsAzure.Storage, Version=9.2.0.0.
The ExecuteQuery does not exist within CloudTable for this version.
This might be your case as well.
Use:
table.ExecuteQuerySegmentedAsync(query, null).Result;
The ExecuteQuery sync is still available for .NET Framework version however for NET Standard use ExecuteQuerySegmentedAsync instead.
Error CS1061 'CloudTable' does not contain a definition for 'Execute' and no extension method 'Execute' accepting a first argument of type 'CloudTable' could be found (are you missing a using directive or an assembly reference?)
CloudTable.Execute Method (TableOperation, TableRequestOptions, OperationContext) accepts a TableOperation object as the first argument, and according to the code you provide, we could find you indeed pass a TableOperation object to Execute method, it should not return the error. Please try to install the latest version Microsoft Azure Storage Client Library for .NET to your project (the code works fine with WindowsAzure.Storage v8.0.0 on my side) and test if same issue will appear. You could also tell us the version of WindowsAzure.Storage you are using now, and then we will test the code with that version.
Besides, please try to use TableQuery to generate a query and call CloudTable.ExecuteQuery method to retrieve the entity.
TableQuery<WorkUser> query = new TableQuery<WorkUser>().Where(
TableQuery.CombineFilters(
TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "Skype"),
TableOperators.And,
TableQuery.GenerateFilterCondition("RowKey", QueryComparisons.Equal, skypeid)));
retrievedSkypeId = table.ExecuteQuery(query).FirstOrDefault().RowKey;
I'm using this code to loop columns of a SharePoint 2013 List.
currentContext.Load(currentList.Fields);
currentContext.ExecuteQuery();
foreach (Field f in currentList.Fields) {
}
No problem with normal columns. But, when I arrive to a lookup column I have this error:
"Unable to cast object of type
'System.Collections.Generic.Dictionary`2[System.String,System.Object]'
to type 'Microsoft.SharePoint.Client.Field'."
I found for example this discussion
This issue came when we were working with TaxonomyFieldValue fields. For us changing references was not an option. This helped:
TaxonomyItem dummy = new TaxonomyItem(web.Context, null);
It will force program to load adequate libraries forcing correct type in runtime.
I had this same issue and updating the references fixed it for me. This question helped me figure it out.
I went from version 14 of "Microsoft.SharePoint.Client" and "Microsoft.SharePoint.Client.Runtime" to version 16 and no longer had the error.

as per suggestion for by #CreativeManix I started investigating petaPeco
Retrieving large number of rows (more than 10 mil) in asp.net mvc application
After adding exact system.data.oracleclient + putting web.config in the bin where mvc is getting compiled in .dll I got following error:

This error shows up when i run the transformation after installation of petaPoco.
One thing I do know the error is coming from "GetCurrentProject" - and probably - "(Array)dte.ActiveSolutionProjects"
I think something is wrong in the way petaPoco is set up with my project! somehow it can't find the activesolution project. I am not too sure how to fix it.
I investigated this.
In my question section I asked few questions:
I was not sure about how to fire transformation/or process of generating Database.CS. So initially I was installing petapoco from the command prompt- I
To do that you just click "Run Custom Tool" by right clicking on the "Database.tt". If your connection string is correct + you are referencing correct Oracle/SQL server data provider + that provider is available in GAC + (if it is oracle and you have the password for the default schema user of the database you are trying to access)- then that should generate the Database.cs
To enable Oracle data client to read the schema out of oracle database I needed to take out following entry:
cmd.GetType().GetProperty("BindByName").SetValue(cmd, true, null);
And everything worked.
Connection string can look like:
connectionString="Data Source=PXWREG;Persist Security Info=True;User ID=XWREG_ACDS_T;password=isacdst"
I am trying to use the FSharp.Data XmlProvider.
According to the samples you can access nested types and create a function that will receive a parameter of one of those types.
https://github.com/fsharp/FSharp.Data/blob/master/samples/library/XmlProvider.fsx (line 177)
However when I try to do the following:
type businessesT = XmlProvider<"Businesses.xml">
type businessT = businessesT.DomainTypes.Business
let testfunc (b:businessesT.DomainTypes.Business) =
b
It seems to work until I actually compiles and then I get
error FS0039: The type 'Business' is not defined
UPDATE:
The problem can be reproduced with the sample from FSharp.Data (XmlProvider.fsx)
adding a type alias after line 205
type Rss = XmlProvider<"http://tomasp.net/blog/rss.aspx">
type test = Rss.DomainTypes.Channel
What is strange is that the sample with the printDiv function is working...
This is most likely caused by some problem with loading the type provider - if the compiler fails to load the type provider, then it cannot run it and so none of the provided types like Business would be defined.
Are you using #r in a script file, or are you referencing the type provider through "Add References" in a project? If you're using #r, check if there is any error message on that line. In case of project, check other error messages output by the compiler.
I already listed some common reasons why type provider fails to load in another answer.
This was probably the same problem as "type provider" not recognized when building project, which has been fixed in FSharp.Data 1.1.10
