Open the "My Snippets" folder - you can determine its location by looking in Edit | Preferences > Folders.

Are there any snippets there, and if so, can you you try deleting them or moving them elsewhere? (You'll need to restart LINQPad after doing this.)

Based on that error, Data Explorer must then be a fork of SQL 2005. I'll lower the version again in the next build.

If the content is HTML, you don't need a DumpContainer - just use a Div and update its InnerHtml when you want to refresh the content:

using LINQPad.Controls;

var div = new Div().Dump();
div.Styles["font-family"] = "consolas";
div.HtmlElement.InnerHtml = "<pre>test <span style='background-color:yellow'>yellow</span> test </pre>";

If the content is large or complex, you can make the updates more efficient by taking a more granular approach:

var span1 = new Span("foo");
var span2 = new Span("bar");
var pre = new Control ("pre", span1, span2).Dump();
// now you can update span1 or span2 by changing their InnerHtml or styles

I just tried with LINQPad 6 Beta and can confirm that it still doesn't work (using help.kusto.windows.net) - I've noticed that you can still make SQL queries in LINQPad 6, but you can't use Linq-To-Sql

Everything works fine in LINQPad 5 though.

Thanks for looking into it.

LINQPad 6 needs schema that can also feed the EF Core context generator, and this requires extra metadata.

I've added an exception-handling test to determine whether the server implements object_definition. Try the latest LINQPad 6 beta and let me know how you get along.

Looks like the class in the child element (span.false) is overriding the parent style. I'll figure out a way to fix this in the next build.

Try the latest beta (6.14.2). LINQPad no longer uses a local URI and populates the DOM entirely with JavaScript. It also retries if the browser fails to respond. This should maximize the chance of it working, although I suspect your browser is messed up in some way.

@JoeAlbahari I am having the same issue, with the exact same productversion and EngineEdition as @RobertBernstein. Although, I am very happy to know that this at least works with LINQPad 5 for the time being.

Note: this works fine in LINQPad 5. Is there planned support for this in LINQPad 6 or am I doing something wrong?

1. Select Add connection.
2. Set Build data context automatically.
3. Set Default (LINQ to SQL), the LINQPad driver.
4. Set SQL Azure.
5. For the server, specify the name of the Azure Data Explorer cluster: help.kusto.windows.net
6. Set Active Directory - Integrated, for signing in.
7. Select Test to verify connectivity.
8. Select OK. The browser window displays the tree view with the databases.

I should be able to browse through the databases, tables, and columns at this point, but it failed for me. When I attempt to expand the "Samples" database, I get the following error:

Here's what I got, @JoeAlbahari. I hope it's helpful!
