Dynamics CRM has very efficient web services using which you can retrieve data such as Organization service Or WebApi. However if you still need to retrieve data from database here is a quick code helper – which i am using in a console application.
//Initiate the connection
using (var connection = new SqlConnection(ConfigurationManager.ConnectionStrings["SQLServerConnection"].ConnectionString))
//create a command variable
using (var command = connection.CreateCommand())
//add query to your command
command.CommandText = "your SQLquery goes here";
// open the connection first and then execute the query using Execute Reader
result = command.ExecuteReader();
here is the app.config which i have used , i am using the windows authentication hence you donot need to mention credentials.
<?xml version="1.0" encoding="utf-8"?>
<add name="SQLServerConnection" connectionString="Server=.;Database=events.website;Trusted_Connection=True;"/>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2"/>
By Now you will have your dataset in “result”; here is another piece of code to read the data:
string contactid= result["columnName"].ToString();
string contact = result["columnName"].ToString();
DateTime createdonDate= (DateTime)result["createdon"];
string type = result["columnName"].ToString();
// close the result
if (result != null)
I hope this helps!
We all need to log errors, information, warnings when writing your console application.
while there are several third party tools/methods available which you use in your solution such as Nlog, Log4net… etc. I would still prefer to create my custom code to generate the log file and capture all details as those tools might work on some machine and on some wont also depends badly on the permissions on the system.
below is simple code that i use :
public static class ErrorLog
public static void Logger(string ErrorCode, string ErrorMsg)
string path = Directory.GetCurrentDirectory();
path = path + "\\Logs\\";
// check if directory exists
path = path + DateTime.Today.ToString("dd-MMM-yy") + ".log";
// check if file exist
// log the error now
using (StreamWriter writer = File.AppendText(path))
string error = "\n" + DateTime.Now.ToString() + ":" + ErrorCode + ":" + ErrorMsg;
catch (Exception ex)
throw new Exception(ex.Message);
add this file to your code and later you can use it in your solution anywhere like below :
kindly note that this will generate the logs file on your directory where the code is running in that case in the “BIN” folder. You can tweak the code to put it somewhere else if you need.
Hope this helps!
As per the recent communication from Microsoft, Microsoft Dynamics CRM SDK will not be available on Microsoft downloads. If you are working on Dynamics 365 v9, well you have to download every component which was available in the SDK individually.
Every tool will be available via NuGet Manager.
The name will be : Developer Guide not Dynamics CRM SDK.
For more information, visit the below blog : https://blogs.msdn.microsoft.com/crm/2017/11/01/whats-new-for-customer-engagement-developer-documentation-in-version-9-0
Here is the step by step information on how to download these tools using powershell : https://docs.microsoft.com/en-us/dynamics365/customer-engagement/developer/download-tools-nuget
i hope this helps.
