    upgrade - MongoDB Driver update issues from version 2.27 to version 3.2.1 - Stack Overflow

    programmeradmin3浏览0评论

    I am using Assembly MongoDB.Driver version 2.27 in my C# code (Targeting to netstandard2.1 as need some backward compatibility for older codebase). When I am changing version of Assembly MongoDB.Driver to 3.2 (Which is newer version), it generates following compile time error. What could be the issue ?

    Error: The type or namespace name 'IMongoQueryable<>' could not be found (are you missing a using directive or an assembly reference?)

    Please note that Version 3.2.1 is much newer version and I have checked the compatibility. This can be found here :

    My Database Server version is 7.0.16.

    I have found few links that says that MongoDB Driver upgrade 3.x has some LINQ Support issues but did not get concrete information around it.

    Can someone please help me to upgrade MongoDB Driver to latest version 3.2.1?

    Reset to default 1

    Typically, when you upgrade a driver from 2.x to 3.x, there are breaking changes. This is called semantic versioning. According to the mongo db documentation found here this is the possible cause:

    The driver replaces the IMongoQueryable interface with the IQueryable interface, following the pattern used by most other LINQ providers. If your application contains references to IMongoQueryable, replace them with IQueryable.
