问题 I am working on a project using an mdf file generated locally using Entity Framework Code First.

问题 I use the data and schema comparison tools in Visual Studio a great deal. I just finished installing VS 2010 on a new VM and realized, of course, that all the saved data connections from my previous installation are not available. Is there a way to transfer these connections between installations of VS 2010? 回答1: I believe you just copy the file from C:\Users\<username>\AppData\Roaming\ Microsoft\VisualStudio\10.0\ServerExplorer\DefaultView.SEView from the installation with the data

问题 I am writting an application and I used Wizard to create DataSets which auto-created their own xml code. This code uses the saved in My.Settings Connection String.

The problem is that when I install the Application to my customer the Connection String will have to change (maybe more than once). So is there a way to change the Connection String used by these objects at runtime ? 回答1: Here's how to

问题 So I am using connection strings in my web.config using SQL authentication. Of course people say this could be a vulnerability as you are storing password in plaintext. However, from what I know, IIS never serves web.config, and web.config should only have read access to administrators and IIS anyway. So if the hacker has gained access to the webserver, then it won't matter what encryption I use because the private key will be on the webserver. Wouldn't encrypting connection string be

问题 What's the best way to store connection string info? I'd rather not just store the db password in NHib.config file. 回答1: Use encryption on the password and/or connection string and store the encrypted password/connection string in a config file of some sort.

问题 Does anyone know if it is possible to create a single connection string that will be accessible to all the projects in a solution (we have about 6). I can create a text file with this information, but we need design time support as well, and it is not practical to have a connection string in every App.Config and Web.config file in the solution. We basically want a Single connection string that is easy to change should the location of the db change, that will also be used by the IDE for design

问题 |DataDirectory|, you had one job. |DataDirectory| on IIS7.5 resolves to: C:\inetpub\wwwroot\appname\App_Data That folder does not exist. The correct folder is: C:\inetpub\wwwroot\appname\bin\App_Data All is well on the dev machine, but when I deploy to the server, AppData is placed within bin\ . I use AppData as shown in any Visual Studio 2010 project and deploy with " Build Deployment Package " (VS2010) then " Import Application " (IIS Manager). I know I can set the path manually with

问题 I used SQL Server CE 4.0 in my windows app and use Entity Framework to create a model of it. It works fine but my problems is that it doesn't have a constructor to change the connection string, and by default it reads the connection string from the app.config file. using (var Context = new MyEntitiesModel(//has no constructor)) { ... } I create a dynamic connection string and using (var Context = new MyEntitiesModel()) { Context.Database.Connection.ConnectionString = entityConnection
