C# to Lakehouse SQL Analytics Endpoint not connecting

[jigmoth]

I have a console app in C# .net framework. I am trying to connect MS Fabric Lakehouse SQL Analytics Endpoint using Service Principal, but it always gives me error 'Could not login because the authentication failed.', when i researched i found in community (authenticate to Fabric Data Warehouse with Service... - Microsoft Fabric Community) it says in SQL query window Create a user with your service principal name and add db_owner role. But when i tried to execute the query it says 'CREATE USER is not a supported statement type.' Its a deadlocak, i want to access Lakehouse tables from C# without user interaction login. Kindly Assist.

//Not working
string connectionString = @"Data Source=msfabricendpoint.datawarehouse.fabric.microsoft.com,1433;
Initial Catalog=insights_LH_PRD;
Authentication=Active Directory Service Principal;
User ID=[ClientId];
Password=[Client_Secret]";
Encrypt=True;
TrustServerCertificate=False;";

SqlConnection conn = new SqlConnection(connectionString);
conn.Open();

If you are tring to connecting MS Fabric Lakehouse SQL Analytics Endpoint using Service Principal

Note: After creating Service Prinipal in Azure Entra ID. You need to add service principal to Fabric workspaces like this:

Make sure to allow access to service principals by enabling below option in Admin Portal:

After providing the access you should be able to do the connection using Service Principal.

Hi @jigmoth ,

It looks like you do not have the necessary permissions.
