问题 I'm working with VWD2010 and as stated in the topic title I have zero intellisense usability for my project. I installed VWD2010 fresh a few months ago to start and noticed that intellisense wasn't working. For the last three months I was working with VS2010 trial and intellisense was working fine. The trial version expired, so now I am back to VWD2010. Intellisense seems to work for NEW projects, so I created a new project and transferred all my files from the VS2010 project. Intellisense

问题 Am trying to learn ASP.NET MVC and search the internet in and out including SO. A lot of questions and answers about |DataDirectory| as where and how. When debugging the site breaks: "The model backing the 'ASPNETDBContext' context has changed since the database was created..." . Then I checked the path: |DataDirectory|ASPNETDBContext.sdf string path = AppDomain.CurrentDomain.GetData( "DataDirectory" ).ToString(); It points to the App_Data of the project but no file there. The DB is entirely

由 ⅰ亾dé卋堺 提交于 2019-12-23 09:43:04
问题 I've enabled Enable Edit and Continue on the Web Properties page and it's also enabled in my configuration, yet Visual Web Developer 2008 Express Edition refuses to allow me to edit source files of an ASP.NET MVC project. I can edit the aspx file with no problem though. Any ideas what's wrong or what's missing? 回答1: If you are targeting x64 or Any CPU on a 64 bit machine you cannot use edit and continue. It only works when you are targeting x32. I set my Platform target to x32 for the Debug

OData / WCF Data Service not working with complex type

由 て烟熏妆下的殇ゞ 提交于 2019-12-10 19:04:42
问题 I'm brand new to OData and WCF data services so this might be an easy problem. I'm using VS Web Developer Express 2010 where I have a very simple WCF Data Service hosted in a console app. It's returning an IQuerable collection of a simple 'Study' class from a repository (located in a separated dll project), which in turn retrieves 'Study' classes from a db project in another dll (so 3 projects in the solution). I also have an 'Experiment' class in the db project and there can be multiple

When to use .mdf and when .sdf?

由 丶灬走出姿态 提交于 2019-12-09 05:25:00
问题 After seeing a lot of things in the internet I haven't found any explanation between the two file types: .mdf and .sdf . .sdf would be a compact version of SQL Server ( .mdf ) I believe. Still they appear utterly different. Have followed the two tutorials on msdn, i.e. MVC Movie App and the Musicstore. Both use .sdf . Partial quote (full): 'First of all it should be "|DataDirectory|ASPNETDBContext.mdf" (notice the extension difference). Your applic...' Both tutorials have the connection
