When using AdomdDataReader.GetValue(int), all the values are strings instead of being properly typed to the type returned in the xml.
After doing some analysis, I found a commented row in XmlaDataReader, row 1021 which explains my problem.
Uncommenting the row and commenting row 1022 fixes our issue, because the default value would be null so the test just after gets properly the field type.
The current code returns object by default, so it never tries to get the proper type.

Is there a good reason for using this row instead of the commented one ?

Scenario:

• Create new .net core application
• Add reference Unofficial.Microsoft.AnalysisServices.AdomdClient nuget package, version 13.0.4001 (latest atm)
• Try to open a connection to an SSAS instance

var connectionString = "Provider = MSOLAP.7; Data Source = hidden Catalog=hidden;User ID=hidden Password=hidden Properties="hidden";Application Name='hidden';";
using (var connection = new AdomdConnection(connectionString))
{
connection.Open();
}

Exception thrown: 'System.IO.FileNotFoundException' in Microsoft.AnalysisServices.AdomdClient.dll
An unhandled exception of type 'System.IO.FileNotFoundException' occurred in Microsoft.AnalysisServices.AdomdClient.dll
Could not load file or assembly 'System.Configuration.ConfigurationManager, Version=0.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.

Hi i'm testing your lib (version 15.3.1.1) and facing the same excetion as #7

but in my case i'm pretty sure the connection string is correct and i receive a token whick seems ok according to jwt.io

here is the complete exception :
System.Private.CoreLib: Exception while executing function: process. System.Private.CoreLib: Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "Microsoft.AnalysisServices.AdomdClient.XmlaSR.resources" was correctly embedded or linked into assembly "AdomdClientNetCore" at compile time, or that all the satellite assemblies required are loadable and fully signed

Any suggestion would be appreciated.

I am getting a warning: CSC: Referenced assembly 'AdomdClientNetCore, Version=15.3.1.2, Culture=neutral, PublicKeyToken=null' does not have a strong name.

Following this guide. This issue does not occur in version 15.3.1.

Version: 15.3.1.1

Error message: Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "Microsoft.AnalysisServices.AdomdClient.XmlaSR.resources" was correctly embedded or linked into assembly "AdomdClientNetCore" at compile time, or that all the satellite assemblies required are loadable and fully signed.

When a AdomdConnection is closed, an exception is thrown.
Exception: "System.OperationCanceledException: 'The operation was canceled.'"

This happens both when calling the close method of the AdomdConnection class and when getting out of a using(AdomdConnection) block.

Errors which get thrown with string-based descriptions from the resource files cause a MissingManifestException to be thrown.

Hi! Thanks for the library! I found that ExecuteCellSet() throws an exception due to wrong code in MDDatasetFormatter.ReadCellInfo() method. There is commented out line "goto IL_136;", it should be restored (and label moved out from the try block), then it works.

I did try it with query as well but the same error.
