In Docker for windows, how do i access a webapi running on my dev machine from the container i aslo have on my machine? - asp.net

Question

I am currently running docker for windows with a container using the asp.net core 2.0 image.
I also have a web api application running on iis on the development machine (the same machine i have docker installed with the container)
I need to be able to make an API request to the api on my dev machine.
I cant seem to get this to work.
Any help would be appreciated
Update:
My docker file
FROM microsoft/aspnetcore:2.0 AS base
WORKDIR /app
EXPOSE 80
FROM microsoft/aspnetcore-build:2.0 AS build
WORKDIR /src
COPY mysol.sln ./
COPY mysol.Web/mysol.Web.csproj mysol.Web/
RUN dotnet restore -nowarn:msb3202,nu1503
COPY . .
WORKDIR /src/CraOrchestrator.Web
RUN dotnet build -c Release -o /app
FROM build AS publish
RUN dotnet publish -c Release -o /app
FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "mysol.Web.dll"]
I am running the container with
docker run -dit -p 1253:80 -v c:/data:/data --name sol mysol:latest

There should not be any problem for your containerised app to reach an app running on the host or even a different container. The problem may be in the .dockerfile.
You only need the executables in your image to correctly run your application. Your .dockerfile may look like:
# use microsoft dotnet core as base image - including ASP.NET Core
FROM microsoft/dotnet:2.0.5-runtime
# set the working directory
WORKDIR /app
# copy executables
ADD . /app
# make port 5050 available - should not matter much since this is a client app
EXPOSE 5050
# run app
CMD ["dotnet", "mysol.Web.dll"]
To create the image:
docker build -t app-image .
To run the container (and so your application):
docker run --name myapp -p 4000:5050 app-image
You may not require the port setup since the application you run is the one performing requests to the Web API running in IIS.
