Allow setting timeouts for the design-time tools

[roji]

Add a command-line option which controls the ADO.NET timeouts. This would allow users to set a higher timeout for e.g. migrations without needing to manage multiple connection strings.

We could probably have a single cmdline option to manage both the connection and command timeouts.

Raised in https://github.com/dotnet/efcore/issues/27783#issuecomment-1105585740 and also discussed in #22287.

I think it would be better to set the timeouts to be 0 (indefinite wait) so that way it works for everyone out of the box without needing to add a command line option to dotnet-ef.

However I would take it a step further and also optimize the generated sql that is used for scaffold as well.

Why? Because I feel that dotnet-ef has plenty of options already that a developer must keep track of, why add 1 more?

If there is a need for this in certain environments it should be managed via the connection string IMHO

I tried it via ;Connection Timeout=0 it did not change the issue where scaffolding would still time out.

And ironically it's doing it for a db with only 9 tables.

Edit: looks like it was ;Command Timeout=0 😃

You should be using Command Timeout and a newer version of Microsoft.Data.SqlClient. If that does not work I suggest you create a new issue with the full error message.

I use the version of SqlClient from 7.0.0-preview7 of efcore when scaffolding (Debug), but use 6.0.8 of efcore at runtime (Release).

Although I did fix that and I now run into this:

System.IO.FileNotFoundException: Could not load file or assembly 'Humanizer, Version=2.14.0.0, Culture=neutral, PublicKeyToken=979442b78dfc278e'. The system cannot find the file specified.
File name: 'Humanizer, Version=2.14.0.0, Culture=neutral, PublicKeyToken=979442b78dfc278e'
   at Microsoft.EntityFrameworkCore.Design.Internal.HumanizerPluralizer.Singularize(String name)

I see that preview7 should be using 2.14.1 of humanizer however for some reason when scaffolding it wants to look for 2.14.0.

Looks like you are mixing dependencies. Won't work .

Looks like you are mixing dependencies. Won't work .

Except when scaffolding I have only these dependencies:

    <PackageReference Include="IDisposableAnalyzers" Version="*-*">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
    <PackageReference Include="StrongNamer" Version="*-*" />
    <!-- So building works with scaffold. -->

    </PackageReference>
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="7.0.0-preview.7.22376.2" />
    <!-- We need to include the package version when scaffolding. This is to ensure building during scaffold works. -->

    <PackageReference Include="System.Security.Cryptography.Cng" Version="*" />

I tested it by removing the need to consume all of the non-efcore packages when scaffolding and discovered that it's still having the same issue (by removing all **/*.cs files from the compilation when scaffolding).
