You may need to supply runtime policy

mdmoura commented 8 years ago

On an ASP.NET Core 1.0 RTM project I keep getting the following Warning:

Warning CS1701  Assuming assembly reference 'System.Runtime, Version=4.0.0.0, 
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' used by 'System.Threading.Tasks' matches

of  'System.Runtime', you may need to supply runtime policy App.NETCoreApp,Version=v1.0

Any idea what might be wrong? Do you need more information?

BTW one of the Warnings is on the following code line inside a Controller Action:

return BadRequest(reply);

pranavkm commented 8 years ago

Tried out a sample app with your project file and I couldn't see the warning. Perhaps try cleaning your packages dir (http://docs.nuget.org/consume/command-line-reference#locals-command nuget.exe locals all -clear) and your repo and see if that helps at all?

mdmoura commented 8 years ago

@pranavkm Yes, that solved it. Thanks.

prabhakarreddy1234 commented 8 years ago

I manually installed "System.Runtime": "4.1.0" . It worked.

I am having this issue too, but nuget locals all -clear did not solve the issue for me.

Before you do anything drastic or laborious, try closing and reopening VS. That solved it for me.

pranavkm commented 8 years ago

@Phrohdoh I'm not entirely sure what might cause your issue. @DamianEdwards where would this issue go?

DamianEdwards commented 8 years ago

I'd log it in https://github.com/NuGet/Home/issues I think

mdmoura commented 8 years ago

Usually I am able to solve this by deleting the DLL files, restart VS and rebuild the Application.

But this keeps happening and is really annoying.

Any ETA for a solution to this issue?

@guybartal I tried your project locally and that don't see this issue. Are you able to consistently repro it after clearing your NuGet caches? See https://github.com/aspnet/Mvc/issues/5050#issuecomment-233974980 for details on how to go about it.

Bit of a tangent, I'd also recommend not mixing long term support packages ("Microsoft.AspNetCore.Authentication.OpenIdConnect": "1.0.0, "Microsoft.EntityFrameworkCore.SqlServer": "1.0.1") with 1.1.0 bits. The 1.1.0 versions of these packages is part of the supported matrix.

nteague22 commented 7 years ago

Are there any updates to the new netcoreapp1.1 projects using .csproj files? I have been working with them, and am aware they are alpha, but wanted to see if a solution existed?

I have tried the restore and tried dotnet restore after clearing the entire nuget cache, but no luck

davidfowl commented 7 years ago

@nteague22 what about them?

nteague22 commented 7 years ago

In VS Code, I get the same issue of a constant warning to supply runtime policy, that it mismatches the versions. It may be from using SDK 3 with VS Code, and I was checking to see if the csproj format would get attention outside of VS2017

I added the code line to somehow try to solve the problem:

    <PackageReference Include="System.Runtime" Version="4.3.0" />

But does not seem to help ...

This problem has been happening in VS 2015, VS 2017 and Visual Studio Code with project.json or .csproj file.

Cleaning the cache or deleting the content of BIN folder sometimes solves it for a while but I get it again very soon ... Not sure what triggers it ...

davidfowl commented 7 years ago

This problem has been happening in VS 2015, VS 2017 and Visual Studio Code with project.json or .csproj file.

But I'm looking for a repro and based on what you wrote, you're using VS2017 RC right? If you have a separate project.json repro, can you provide that as well?

You shouldn't need the System.Runtime package reference, it's redundant.

mdmoura commented 7 years ago

@davidfowl In this case I am using Visual Studio Code not VS 2017. And I am using the .csproj not the project.json. I am also using the following version of dotnet tools:

.NET Command Line Tools (1.0.0-preview4-004124)

Product Information:
Version:            1.0.0-preview4-004124

Addind the System.Runtime reference was just an attempt to solve it.

nteague22 commented 7 years ago

@itn3000 Is right, I wondered if it was Omnisharp or a tooling mismatch from SDK 3.

I had been using the csproj just like the others

paulrayer commented 7 years ago

@Monte-Christo, closing and reopening the VS worked for me.

GiantappMan commented 7 years ago

just need to restart VS

agokrim commented 7 years ago

1- Delete the content of \bin\Debug 2- Rebuild 3- Restart VS

Zeheva commented 7 years ago

@agokrim, worked for me thanks!

BenjiZombie commented 7 years ago

For anyone using VS 2017, in my .NET Core .csproj file, I had an empty <NoWarn> element, which was the culprit:

<PropertyGroup>
    <TreatWarningsAsErrors>true</TreatWarningsAsErrors>
    <NoWarn></NoWarn>   <<-- REMOVE THIS
    <GenerateDocumentationFile>false</GenerateDocumentationFile>
    <PreserveCompilationContext>true</PreserveCompilationContext>
</PropertyGroup>

Builds successfully after removing that <NoWarn> element.

adamjez commented 7 years ago

As @BenjiZombie pointed out, when specifying custom <NoWarn>, you should include these warnings types 1701;1702;1705.

Actually, when you remove <NoWarn> element and then look at project properties (GUI Editor of csproj), you will see property Suppress Warnings equals to 1701;1702;1705

kellypleahy commented 7 years ago

So are we saying the default for VS is to turn off these warnings on all projects? If so, isn't that a sign of a problem? Why do these warnings occur? Is there an explanation somewhere as to the meaning of these warnings (in the context of these projects)? I've looked at the doc for these warnings, but that doesn't tell me what sort of gremlins I can expect from ignoring them indefinitely.
