Inclusion of edmxResourcesToEmbed fails build in linux due to path slash

[joebone]

[ Might be a duplicate of #1378 , but that is marked as closed and fixed, and at least as far as I am aware, it is not ( or at least hasn't been released ) ]

When building a project that contains edmx files in linux (alpine docker in this case), the build fails.
It seems to be because the backslash is hardcoded when generated, but is not read the same way when building.

Steps to reproduce

Have a netcoreapp3.0 project, include an edmx, and build it.

Further technical details

Output of failed build:

however, the files DO exist, BUT because the backslash is hardcoded, "Model" hasn't been generated as a folder, so we have files named "Model\asd.csdl" in the parent folder:

/src/xxx # find . -name "*.csdl"
./obj/Debug/netcoreapp3.0/edmxResourcesToEmbed/Model\asd.csdl

@joebone What EF package version are you using?

[husseinraoouf]

I can confirm this issue happens to me
i am using ef 6.3 and .net core 3.0

[joebone]

@ajcvickers sorry, didnt get a notification, was using the standard release non-preview NuGet 6.3.0

In the end as a workaround, we changed the library dependency to generate a nuget package and imported that when building in docker, but evidently its not ideal.
