WebAPI OData无法加载microsoft.data.odata版本= 5.6.0.0

Question

When I construct Asp.Net WebAPI using VisualStudio 2013, adding

Web API 2 OData Controller with actions using Entity FrameWork

after add successfully, I run the API, then the error occur：

Could not load file or assembly 'Microsoft.Data.OData, Version=5.6.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

How to solve it?

Answer 1

I spend long time to try and seems find the solution：

1. Open Tools > Library Package Manager > Manage Nuget Packages For solution

and serach the word "data" shows:

2. As the error says Microsoft.Data.OData, Version=5.6.0.0" Could not load , you can find that there's Microsoft.Data.OData installed here, name OdataLib for OData v1-3 , but its version is 5.6.3 not 5.6.0.0

3. Hence now manage it and uncheck all project to uninstall it, but you'll meet the error Microsoft.AspNet.WebApi.OData 5.0.0 depends on it , hence you should first uninstalled Microsoft.AspNet.WebApi.OData 5.0.0

4. Then Uninstall other three packages, their id are :

.

Microsoft.Data.OData
Microsoft.Data.Edm
System.Spatial

5. reinstall Microsoft.Data.OData -Version 5.6.0

https://www.nuget.org/packages/Microsoft.Data.OData/5.6.0

using Package Manager Console

Install-Package Microsoft.Data.OData -Version 5.6.0

then the three orange will be reinstall with ver 5.6.0.0

6. reinstall Microsoft.AspNet.WebApi.OData 5.0.0

https://www.nuget.org/packages/Microsoft.AspNet.WebApi.OData/5.0.0

using Package Manager Console

Install-Package Microsoft.AspNet.WebApi.OData -Version 5.0.0

7. Then I can run the API without error
