Sdk: Can not find compilation library location for package exception when using packed project

[marcuslindblom]

I have a small example project where I embed a couple of views like this:

``` c#
namespace Brics
{
public static class ServiceCollectionExtensions
{
public static void AddBrickPile(this IServiceCollection services) {
services.Configure(options =>
{
options.FileProviders.Add(new EmbeddedFileProvider(
typeof(ServiceCollectionExtensions).GetTypeInfo().Assembly,
baseNamespace: "Brics.EmbeddedResources"));
});
}
}
}

``` json
{
  "buildOptions": {
    "embed": {
      "include": ["EmbeddedResources/**"]
    }
  }
}

When the project is packed using dotnet pack I install the NuGet package and use the extension method AddBrickPile, then I get the exception below. The embedded directory does not seem to be available?

[dazinator]

I am also getting this exception when trying to use a middleware extension method in library added as a nuget package. What does it mean?

[mirhagk]

I'm getting this exception as well for one of my controllers in my site that I deployed to azure (using the continuous integration feature of azure websites)

[smax48]

I am getting this exception when I reference a nuget package that I want to use as an app part.
This error happens even if I don't register the app part!!! Just adding a nuget reference is enough to crash...

[TheRealPiotrP]

Can someone add a small repro with steps for how the exception should be hit locally?

[psulek]

@piotrpMSFT , we have same issue, we have:

• asp.net core web mvc app
• in app.config we have configured privatePath Modules like:

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <probing privatePath="Modules"/>
    </assemblyBinding>

And such error is trowed when we want to render "ViewComponent" from assembly loaded from that Modules path. Such assembly is registered into ApplicationPartManager, like:

var applicationPartManager = app.ApplicationServices.GetRequiredService<ApplicationPartManager>();
applicationPartManager.ApplicationParts.Add(new AssemblyPart(assembly));

Update:
When we move assemblies from Modules into bin folder with rest of application assemblies (eg: ..\Web.App\bin\Debug\net462\win7-x64\) everything working fine.

Yup - Get the same issue in Orchard Core

[bgl3317]

I am getting this error when adding a nuget.config to my asp.net core app to install packages to a local folder instead of the default %userprofile%\.nugetpackages location:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <config>
        <add key="globalPackagesFolder" value="../../packages" />
    </config>
    <packageSources>
        <add key="NuGet" value="https://api.nuget.org/v3/index.json" />
    </packageSources>
</configuration>

Doing so does install the packages to a local /packages directory, however then I got "cannot resolve dependency" errors when compiling. Those were resolved by adding this line to global.json:
{
"packages": "packages",
"projects": [ "src", "test" ],
"sdk": {
"version": "1.0.0-preview2-1-003177"
}
}
to tell it to look for packages in a relative path directory called packages.

Everything compiles great at this point, however now I get this "InvalidOperationException: Can not find compilation library location for package" for any package found in my local packages directory. The error goes away if I manually copy the packages into %userprofile%.nugetpackages, but I don't want to depend on that global location at all. I want to keep everything self-contained so I can check in all package dependencies along with source code.

Any ideas? I am stuck at this point. My dotnet version is 1.0.0-preview2-1-003177. Using Visual Studio 2015 Update 3.

UPDATE: @piotrpMSFT, attached a small zip with an ASP.NET Core app that causes the error. Restoring the packages will produce the local /packages folder correctly because of the nuget.config. The build should be successful because of the global.json entry. Running the app throws an error _if %userprofile%\.nugetpackages is empty_. There should be no dependency on this global package location based on the nuget.config and global.json configuration.

I'm having the same issue psulek reported. The modules folder is ignored and I have to manually copy the assemblies into the folder.....I'm wondering if perhaps this is an issue having to do with the fact that we migrated from an older vnext project.

UPDATE: If I manually add the modules as a dependency in the project file, then everything gets included. Not sure why I had to do this manually, but it seems like a small price to pay for interoperability. Very thankful for everyone's hard work on this project!

[livarcocc]

What version of the CLI is being used while reproing this issue? We had a bug in the dependency model where it would only look at the NuGet Cache for packages, but it has since been fixed in 2.0.

[schneiderdaniele]

That sounds like the same issue. For me it is not v2, so I will put the upgrade on my TODO. It will be nice to get rid of my build batch files. Thanks!

[russcam]

@livarcocc just been bitten by this. Here's the tooling I'm using

$ dotnet --info
.NET Command Line Tools (1.0.4)

Product Information:
 Version:            1.0.4
 Commit SHA-1 hash:  af1e6684fd

 OS Version:  10.12
 OS Platform: Darwin
 RID:         osx.10.12-x64
 Base Path:   /usr/local/share/dotnet/sdk/1.0.4

With a NuGet.Config in the root of the solution to restore packages to a local dir rather than globally

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <config>
        <add key="globalPackagesFolder" value="packages" />
    </config>
</configuration>

Starting up an asp.net core application that depends on a library not installed in the global package cache but is installed in the local dir yields

^CApplication is shutting down...

restoring packages to the global nuget cache fixed this issue.

[livarcocc]

This is a known issue in the runtime and some runtime libraries actually that has been fixed for 2.0. I would suggest either sticking to the regular nuget cache or upgrading to 2.0.

I am closing the issue as I don't believe there is anything we can do for 1.0 (or in the CLI). But feel free to re-activate if I missed something.

[alexvy86]

@livarcocc any chance this would this affect assembly references (not NuGet package references)? I'm seeing the same exception, but in relation to a DLL that I manually added as a reference in my project in Visual Studio. Just adding the reference doesn't cause issues, but when I start referencing things inside it, my web app (asp.net core, targeting netcoreapp2.0) starts complaining when I try to debug it or publish it.

The fact that the error says "Cannot find compilation library location for package '' makes me think something is trying to process this reference as if it were a NuGet package, not reference to a local file...

I'm aware this repo is for the CLI so if there's a better place for my issue, let me know.

[brantburnett]

@alexvy86

i ran into a similar problem, and was able to fix it by adding this property to my csproj file:

<MvcRazorCompileOnPublish>false</MvcRazorCompileOnPublish>

The problem appears to be specific to MVC when it tries to precompile views.
