问题 I have a .NET 4.0 Web Forms app that I am running with the beta Oracle EF-aware data provider, and I want to perform "unobtrusive" Oracle deployment to a Win2K8 box, as shown in many SO solutions.

问题 I am working on a web-based application using asp.net 4.0. I have some dlls I am using in the GAC that have some embedded dependencies on older dlls. I have Configured the assemblies so that the dependency redirects to the correct version of the dll on my machine. This works perfectly in a 3.5 or lower version application, however, when I try to build an asp.net 4.0 application based on the same dlls, it chokes with an error like: Could not load file or assembly 'ControlReferencedByMyDll,

问题 In a .NET 4 web application I've set the property "renderAllHiddenFieldsAtTopOfForm" to "false" in the web.config. Unfortunately the hidden fields are still at the top. Why is this? Does some other setting override it? "pages" property in web.config: Screenshot of top of the form: ide it? 回答1: From the docs: all system-generated hidden fields are rendered at the top of the page.

问题 I have implemented System.DirectoryServices.AccountManagement for authentication into my webapps finding users (UserPrincipal) byidentity given username. However, I have several cases where I need to get AD accounts given only an employeeID. Is there a good way to get a UserPrincipal (or even just the sAMAccountName) given an employeeID in AccountManagement? I currently have this working to grab users by username: PrincipalContext adAuth = new PrincipalContext(ContextType.Domain, Environment

问题 I need to enable caching in my asp.net application, but I do not want to use the webserver's memory for holding cache objects. If I add the page directive for output caching will the page be stored in the asp.net cache object? Thanks! 回答1: The default behaviour is to store the content in memory in the same way as HttpRuntime.Cache (actually in an internal HttpRuntime.CacheInternal which behaves similarly to the publicly visible cache), but in ASP.NET 4.0 you can write your own provider to
