Posted on by Stuie 255

Hi

I've been trying to change to oAuth since my connections started to fail today.
I've used what I've seen on the net but it's not working.

M previous code was;

        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
        CrmServiceClient service = new CrmServiceClient(ConfigurationManager.ConnectionStrings["CRMLIVE"].ConnectionString);

And Ive changed to use a new conncegion string like

            CrmServiceClient service = new CrmServiceClient(ConfigurationManager.ConnectionStrings["CrmConnectionString"].ConnectionString);

In my web.config i have the string;

It's not working. LastCRMerror is Unable to Login to Dynamics CRM

And Object reference not set to an instance of an object

HELP!

    Hi,

    I have created new console application to connect to CRM from C#. Please download the source code from my github page link below and replace UR, Username & Password

    github.com/.../WorkWithCsharp

    Make sure you are updating your assembly to latest version using NUget package manager.

    Please mark my answer verified if this is helpful!

    Stuie,

    The connection string looks OK from what I can see. It certainly looks like the ones I have that work.

    This may seem like a silly question but are you using an up to date version of the CoreAssemblies from Nuget?

    The connection failed errors are not that helpful, sometimes a slightly out of date DLL can be all it takes.

    Regards,

    Shaun
