OrganizationServiceProxy is null

I am new to WCF implementation.

I have following code which was working fine, but somehow it has stopped working and giving following error:

Unable to Login to Dynamics CRM OrganizationWebProxyClient is null OrganizationServiceProxy is null

Following is the code snippet

private static IOrganizationService GetService(string url, string uname, string pwd)
{

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

string servconn = (!string.IsNullOrWhiteSpace(url) && !string.IsNullOrWhiteSpace(uname) && !string.IsNullOrWhiteSpace(pwd)) ? "AuthType=Office365;Username=" + uname + ";Password=" + pwd + ";Url=" + url
: Convert.ToString(ConfigurationManager.ConnectionStrings["CRMConString"].ConnectionString);

CrmServiceClient c = new CrmServiceClient(servconn);

IOrganizationService Service = c.OrganizationWebProxyClient ?? (IOrganizationService)c.OrganizationServiceProxy;
return Service;
}

Kindly help me with this.

Hi,

Please refer to the following documentation:

Use connection strings in XRM tooling to connect to Microsoft Dataverse (Dataverse) - Power Apps | Microsoft Docs

It states that:

Office365 AuthType is deprecated and we recommend to use OAuth as the preferred authentication type.

This section also provides a sample code for using OAuth authentication.

Details about the Deprecation:

Important changes (deprecations) coming in Power Apps, Power Automate and customer engagement apps - Power Platform | Microsoft Docs

To allow for transition of customers and partner applications:

Effective October 2020, the authentication protocol will be retired for all new tenants.
Effective October 2020, the authentication protocol won't be available in all new regions.
Effective April 20211, the authentication protocol will be retired for all new environments within a tenant.
Effective April 2022, the authentication protocol will be retired for all new and existing environments within a tenant.
