我尝试过：



我搜索但找不到任何...

What I have tried:

I searched but cannot find any...

这个错误通常是因为包的版本不兼容而发生的。

喜欢这个块：

This error usually happens because of incompatible versions of packages.
Like this block:

2.0.0-preview1-final" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="2.0.0-preview1-final" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.0.0-preview1-final" />

尝试将版本减少到1.1。*

这将解决您的问题..



由于某些软件包不兼容与其他的相比，它们太高或太低。

Try to reduce the versions to 1.1.*
And it will fix your problem..

Incompatible consistency because of some packages are either too high or too low compared to other ones.
