update all nuget to 2.0, install Volo.Abp.Localization nuget package for AbpValidationResource

and startup failed

This is because of: https://github.com/abpframework/abp/issues/2499
You need to make necessary changes and re-compile your solution(s).

Installed Volo.Abp.Validation Package and using Volo.Abp.Validation.Localization in DomainShareModule.
and rebuilt solution,but i cannot startup it.


sorry , i forgot to do this

Maybe developers need upgrading documents. :D

When you upgrade (especially a major version) check the release notes.
For example, in v2.0, we've written all breaking changes to the release notes: https://github.com/abpframework/abp/releases/tag/2.0.0
Every breaking change issue documents its own solution. For example, https://github.com/abpframework/abp/issues/2499 explains AbpValidationResource change and the actions need to take.
https://github.com/abpframework/abp/issues/1442 is a document explains upgrading in general, rather than individual upgrades.
