Why can't I delete a application?

Every time I try to delete one of my applications, it asks me to confirm, then waits for a few moments and throws a .NET exception in the modal window with the error "Timeout expired".

I have noticed the same behavior since 4.1.0.

Product: BuildMaster
Version: 4.3.8

Must have a lot of logs... I would try to use the API method to delete it, or increase the sql timeout by editing the connection string.

Thanks for your response. Where do I find the connection string?

It's in the web_appSettings.config file in the WebApp folder; once you change that, you'll need to restart the web application for it to take effect.

I have set the connection timeout to 5 minutes, but still getting the error.

The actual error message provided is: The wait operation timed out

Is there some queries I can use to delete the application directly from the database?

You could try calling the stored procedure directly via the SQL API:

DECLARE  @B VARBINARY(MAX) 
SET @B = CAST('yourname' AS VARBINARY)
SET CONTEXT_INFO @B

EXEC Applications_PurgeApplicationData @Application_Id

or view it in SSMS to see the actual SQL.
