@christothes This solves the issue for me.

To awnser your question, for me it wasn’t in an Azure Function context. I was using it to write my workflow data to tablestorage.

Btx, thnx for the quick fix!

I have a fix, but here is a workaround in the meantime. The issue only exists when the TableClient is created with the connectionString constructor. Here is how you can take a connection string and turn it into a TableSharedKeyCredential so that the other ctor can be used until a fix is available:

var pairs = storageTableConnectionString
    .Split(';')
    .Select<string, KeyValuePair<string,string>>(p =>
    {
        var pair = p.Split('=', 2);
        return KeyValuePair.Create(pair[0], pair[1]);
    })
    .ToDictionary(p => p.Key, p => p.Value);

string accountName = pairs["AccountName"];
var cred = new TableSharedKeyCredential(accountName, pairs["AccountKey"]);
var uri = new Uri($"https://{accountName}.table.core.windows.net");

TableClient client = new TableClient(uri, "deleteThisTable", cred);
