How to connect to database from exist .edmx file?
<p>Our build engineer has left for another company.</p>

<p>He's hand over his project to me.
But I usually code not using EF, so I don't know something, his using Entity file like <code>EntityDataModel.edmx</code> contain all data.</p>

<p>I don't know how to connect to this.
I usually connect to SQL Server by <code>connectionString = ...etc</code>.
I also find this string in his application like:</p>

<p><code>&lt;connectionStrings&gt;&lt;add name="PCApp_TaxitechEntities" connectionString="metadata=res://*/EntityModel.EntityDataModel.csdl|res://*/EntityModel.EntityDataModel.ssdl|res://*/EntityModel.EntityDataModel.msl;provider=System.Data.SqlClient;provider connection string=&amp;quot;data source=SDDMS-010\SQLEXPRESS;initial catalog=PCApp_Taxitech;user id=sa;password=;MultipleActiveResultSets=True;App=EntityFramework&amp;quot;" providerName="System.Data.EntityClient" /&gt;&lt;/connectionStrings&gt;</code></p>
