问题 I am using the following C# OData packages, in a .NET Web Api project: Install-Package Microsoft.AspNet.OData Install-Package Microsoft.AspNet.WebApi.OData When following Microsoft's example Use Open Types in OData v4, everything seems to work as expected, as long as the open type does not contain additional nested open complex types. This means that this will work fine: public class WplController : ODataController { private List<AbstractMongoDocument> _documents = new List

问题 I want to run tests with Effort and to do that I need to specify a connectionstring that also contains a reference to .csdl, .ssdl , and .msl files. The (non-working) connectionstring looks like this now: <add name="SQLAzureConnection" connectionString= "metadata=res://*/Model.projectContext.csdl| res://*/Model.projectContext.ssdl|res://*/Model.projectContext.msl; provider=System.Data.SqlClient; provider connection string="Data Source=(LocalDb)\v11.0;Initial Catalog=Database_Nieuw;Integrated

问题 I have DAL (model first entity framework 4.1) and Service which is using it in separate projects. Everything was working fine, but after some minor changes (for example I generated model from database) it stoppedd working. I am now getting metadata exception. After many hours of research I downloaded ILSpy and checked that inside DAL.dll there are no resources. My connection string looks like: metadata=res://*/DataModel.TerminalRegistryModel.csdl| res://*/DataModel.TerminalRegistryModel.ssdl|

问题 I have a simple database with 2 main tables with a many to many relationship through a 3rd bridge/join table. This 3rd table has an extra field besides the two keys required, so that Entity Framework transforms it into a full entity rather than a many to many relationship between the other 2 tables. I cannot change this third table in the database itself. Is there a way to ignore the extra field so that EF can do what I want, or a way to manually transform the bridge table into a many to many

问题 I need to create a "virtual" association between these two entities (1-*) so that I can traverse them using linq , but the problem is I cannot touch the database. I have tried to manually edit the edmx many times without success, getting various mapping errors. EDMX: <?xml version="1.0" encoding="utf-8"?> <edmx:Edmx Version="2.0" xmlns:edmx="http://schemas.microsoft.com/ado/2008/10/edmx"> <!-- EF Runtime content --> <edmx:Runtime> <!-- SSDL content --> <edmx:StorageModels> <Schema Namespace=

问题 How can I resolve this error? I have added the Entity Framework 6.1.3 from this link: Download EntityFramework 6.1.3 for Visual Studio 2013 (after uninstalling and re-installing it again and again) Now that it has been added and in the project created a .emdx file using ADO.NET Entity Data Model . When I try to build it, the following error pops: EntityFramework.dll not found (after Compilation) 回答1: Don't uninstall the Visual Studio. Installing the Entity Framework 6 Tools for Visual Studio,
