Strong name errors on initial clone and build

[sandcastle]

@JimBobSquarePants - I have just cloned the repo to add GCP provider support and on the initial build of the solution after initialising the git modules I'm getting a strong name error. I'm not sure if this should be the default experience when building the solution, should it just be a CI build time consideration? It makes it a little difficult to get up and running and contribute a PR if you cant build the solution straight away.

Let me know how I can help improve the experience.

Hi @sandcastle

You should read the Manual Build section of the README. You haven't initialized the git submodules. They certainly complicate things but I don't know of a better way to share the code we need to across multiple repositories.

[JimBobSquarePants]

Hold on, this is ImageSharp.Web! I'm transferring this discussion to the correct repository.

[JimBobSquarePants]

It's your .Net Core SDK preview. We should add a global.json with allowprerelease disabled. Hopefully we don't have to declare a specific SDK version (I don't want to do that)

https://docs.microsoft.com/en-us/dotnet/core/tools/global-json?tabs=netcore3x#allowprerelease

Temporarily you can do this.

[sandcastle]

Great - that did the trick!

{
  "sdk": {
    "allowPrerelease": false
  }
}

[JimBobSquarePants]

Ace, i'll use that elsewhere then!

I'm going to see if I can find out why the NET5 preview does this. We're definitely specifying a public key.
