I need to propagate connection string changes for entity framework, asp.net membership (which are both in the connectionstrings section of web.config) and session state (which is in sessonstate's sqlconnectionstring) in web.config when I adjust these settings in windows azure's service configuration. During development we test our app as a standard asp.net webforms app, but once it is deployed it is running in azure. So we need to allow for the site running in both non-azure and an azure context. That's why we're just relying upon the values in web.config for now.Since these connection strings

阅读更多关于 Why did my Visual Studio 10 stop using App.Config for my SQL connection string?

问题 I have a working database application using WPF and SQL Server 2008 R2, which for two years has been getting its SQL Server connection string from the App.Config file. A few days ago on one dev machine, it started ignoring the App.Config file's connectionString, and is now using a string from somewhere else (looks like either settings.settings, or the DBML file). Why might this be happening, and how can I get it to stop doing that? The app.config starts out like this: <configuration>

阅读更多关于 Failover Partner behavior for Sql ConnectionString with ConnectionTimeout

Ie does it always wait the ConnectionTimeout before going to the failover server? Or does the failover becoming primary mean the client will immediately switch to connecting to the failover disregarding the ConnectionTimeout?
