The .NET Core Identity model has an IPasswordHasher<> interface for for
Hashing a password so that it can be stored in a database
Verifying a provided plain-text password matches a previously stored hash.
I am getting invalid password errors during the login process when the .NET Core Identity model computes a hash from a plain text input and compares it to a password hash value I've returned from Caché. The default hashing algorithm is PBKDF2 with HMAC-SHA256, 128-bit salt, 256-bit subkey, and 10,000 iterations (detailed article on .NET Core Identity PasswordHasher). The algorithm Caché uses is probably different which may be why I am getting errors.
is there any indication that the .NET object representation of Cache objects (i.e. InterSystems.Data.CacheClient.dll) complies with .NET Standard? I'm planning to extend our existing .NET client/server solution with a mobile option by Xamarin Forms and can't find any significant hints in the internet.
I'm just fooling around a bit and made some expreiments with a REST API and a generic object-to-JSON tier:
Hi, I have a CSV file with a list of 5000 records in the following format
Name, Acc, division
Eric, 1234, 567
John, 1235, 987
Peter, 3214, 879
I just want to copy the Acc, division to a global so eventually the global would be like the following:
^People("Customers", "Acc.division")
Can you advice on how I can perform this from the terminal? This is a one time task. I want to read all the values from the csv file and insert them into the global
Does developing a RESTful API in Caché remove the requirement to use the InterSystems.Data.CacheClient.dll and generate proxy classes using the Caché Object Binding Wizard for .NET web development? If anyone has links to sample applications using .NET with Caché and REST Services, I would be grateful if you could share them.
We have an application made in asp.net and want to make a integration for our client who is using cache database. So can any one suggest how to communicate with the database as we are new to this system.
I ran the below query in three different modes. Coordinated Universal Time is 5 hours ahead of Eastern Time so there is difference in value from column 1 and column 2 in ODBC, Display mode, but not in Logical Mode. By default the query executes in ODBC mode when we query the data from outside world(via ODBC connection).
I don't know why query 2 and query 3 outputs different from query 1.
Query 1. Ran in Logical mode, DATEPART() took in memory stored timestamp data(stored in UTC)
We have some productions in Ensemble that uses DotNetGateway to use dll created with .Net. The DotNetGateway is configured with a port number, and then the operation uses that port.
I'm currently exploring alternatives to CSP/services and ODBC/Sql Maps for access to Caché. I'm not seeing a library which would interest me, so am considering creating one myself.
Does 'CacheConnection' in C# use RPC of some sort, or a defined protocol to communicate with Caché, or does it do so over telnet with scripted commands? I would assume the former. If so, is this a publicly documented protocol that can be implemented by library developers?
I trying build a project with .NET and Entity Framework in the Code First method, but Caché return the error " 'VARBINARY' is not a supported type for CAST" when run this sql code:
How can I prevent large number truncation when using the DynamicObject and DynamicArray classes to create JSON in objectscript and then parsing the result in javascript. Are there any global settings that configure the output when using these classes?
I am looking at converting to the new DynamicObject and DynamicArray classes to build JSON. Our current (homegrown) JSON library forces string representation of numbers too long because of errors we were seeing with long numbers being truncated on the client, I am hoping to accomplish the same with the new classes.
We have created a dll with .Net that generates a MS Word document with a template. The .Net method works, we have tested it with Visual Studio and it generates the document.
But once we have created the dll and embebed it in Ensemble through the Wizard, when we try to execute the method that generates the document, it doesn't work. It doesn't throw us an error, it simply doesn't open the template.
We have seen that MS Word program is opened, but that's all.
I need to pass an equivalent of .Net Dictionary<string, int> instance from .Net to Caché. In the application, the Caché .Net provider has been used so far, so we came up with passing it as an instance of array of data types. However, the only way to fill the array we are aware of is to use its Add() method which invokes a call to the server instance method of the array for every key-value pair inserted.
Presenter: Jeff Semmens Task: Model and access data as objects in .NET without designing the database first Approach: Use InterSystems Entity Framework
Description: Come and experience how you can design your database model in .NET and evolve it over time by leveraging the Entity Framework.
Problem: Current bindings require database-first design. I cannot design my model in .NET.
Solution: The Entity Framework is an object-relational mapping framework that allows data-oriented applications to model and access their data as objects in .NET. Database- first is still supported but will fade away in future releases.

We do have a production including a SOAP.OutboundAdapter that make a request to a .NET WCF Service. The response from that service vary in size. When it come to large one, we talk about maybe 8000 records (with 6-8 attributes per record) in xml, the adapter always give a timout. Even if we put a high number of seconds or set -1. After 1 1/2h still nothing get back. It's just standing there and waiting for ever.
Our .NET developer have look at it (on the WCF-service) and from ther point of view they say that it seems like Ensemle can't handle such big responses.
