Publish fails in visual studio 2017.

[ghost]

Hi,
I want to publish an "ASP.Net MVC Core 2.0" project, which contains some library as references (They are not NuGets or projects). The project is working fine in the visual studio but it throws the following exception.

	Cannot find compilation library location for package 'Olive'

@hamidmayeli this is likely a dup of https://github.com/dotnet/core-setup/issues/2981 (I think you're on that thread too). Does the workaround I listed there - https://github.com/dotnet/core-setup/issues/2981#issuecomment-322572374 - work for you?

[Eilon]

Yup, looks exactly like https://github.com/dotnet/core-setup/issues/2981.

Dear @Eilon and @pranavkm , It is the same error and I use a workaround for this issue and it is fixed only for debugging time. I need to publish and it fails on publishing time. Therefore, I think it is not a duplicated issue.

[Eilon]

@pranavkm - any ideas?

[pranavkm]

Not off the top of my head. I'll investigate.

I have the same issue, the workaround allowed me to run the project in VS but when I publish it I get an error

As a work around I added this to my csproj file within the PropertyGroup section and it allowed me to publish the app
<MvcRazorCompileOnPublish>false</MvcRazorCompileOnPublish>

@hamidmayeli you would have to configure the same set of services to also work during design time. Precompilation supports this using IDesignTimeMvcBuilderConfiguration (See https://github.com/aspnet/MvcPrecompilation/blob/dev/testapps/ApplicationWithConfigureMvc/Startup.cs#L8). You'd move the snippet provided in https://github.com/dotnet/core-setup/issues/2981#issuecomment-322572374 into IDesignTimeMvcBuilderConfiguration.ConfigureMvc and that should work.

That said, there are issues with the way the tool loads the type which might require more refactoring (See aspnet/MvcPrecompilation#207)

[pranavkm]

@hamidmayeli the other alternative is to disable precompilation the way @proskilly does.

[pranavkm]

Closing this since once we have the service collection configured in IDesignTimeMvcBuilderConfiguration this does get resolved. Feel free to reopen if you have further concerns.

@proskilly Thanks I was able to fix it using the same tag
false

[jamsheedmp]

Thanks proskilly,
You saved my time.

I got that error when I used <br> tag. Then I changed <br> to <br/> and it got fixed.
