Can not use EF core 3.1 in .net 6

[ponyspeed888]

Try to use EF Core 3.1 in a .net standard library. When using this library in .net 6 project I got this error :

System.TypeInitializationException
Message=The type initializer for 'Microsoft.EntityFrameworkCore.Query.QueryableMethods' threw an exception.

Expected : There should be no issue as .net standard 2.0 is supported by all .net core version and EF Core 3.1 target .net standard 2.0

@ponyspeed888 This is a duplicate of #24002, which is fixed in 3.1.14. Your application is using 3.1.10, and so does not have this fix. It is important to always use the latest patch version of a release to get important fixes, including those that might impact security.
