Problem Connecting to Dynamics using XRM Tooling

Good Day,

I have been searching through alot of post on the different messageboards, however i haven't found any that resolved my issue.

i am trying to dynamics 365 using XRM tooling. It worked perfectly a month ago, however it suddenly stopped.

After investigation it looks like it gets the environment information fine from the CrmServiceClient connection string, however, the user authentication isnt getting recognised. the OAuthuserid is empty("") and the OrganizationServiceProxy is all null.

I have a suspicion that it has something to do with the version, the CRM Version is now 9.1.0.14432 , while the SDKVersionProperty is still 9.0.44.892.

i know my connection string is correct, seeing it was working perfectly fine a month ago. the format i used is as follows.

<connectionStrings>  
    <add name="Dynamics365Connection" connectionString="AuthType=Office365;Username=jsmith@contoso.onmicrosoft.com; Password='enterpasswordhere';Url=">contoso.crm.dynamics.com;RequireNewInstance=True;" />  
</connectionStrings>  





does anyone know if there is a new requirement when doing api connections using xrmtooling ? 
Thanks

Hello,

Connection string should look like following:

Just doublecheck that there is no additional quotes and so on.

Inside your code just stop using Proxy - check this post - https://docs.microsoft.com/en-us/powerapps/developer/common-data-service/authenticate-office365-deprecation

Just use CrmServiceClient instance - it exposes all required CRUD and Execute methods.

How do I use the CrmServiceClient instance to do something like a WhoAmI ? or an execute ?

You can use execute. Something like:

var client = new CrmServiceClient("connectionstringhere");

var WhoAmIResponse = client.Execute(new WhoAmIRequest()) as WhoAmIResponse;

Is the O365 authentication safe to use ? as it says in the link you provided that I should use the oAuth method and create an app on azure AD.

What do you mean safe? If you don't plan to put this connection string to place that is available to multiple people - it's safe. It's recommended to use oAuth authentication so you can got that path as well.
