Heroku deploy .net console application

Question

I'm trying to deploy my console app(.net core 3.1) to heroku.

I don't have much experience with it. I have a buildpack and that's all I have. Tried to deploy with that buildpack.

I got following error

C:\Users\SYDNEY\Desktop\twitchbot>git push heroku master

following is my root file: Anyone got idea how to fix this?

Answer 1

If you already have Assemblyinfo.cs you can remove that file and add the following in.csproj file

<PropertyGroup>
    <Company>Name</Company>
    <Authors>Author</Authors>
    <Version>1.0.0</Version>
    <AssemblyVersion>1.0.0.0</AssemblyVersion>
    <FileVersion>1.0.0.0</FileVersion>
</PropertyGroup>

  <PropertyGroup>
    <GenerateAssemblyInfo>true</GenerateAssemblyInfo>
  </PropertyGroup>

Else if you need to keep the assemblyinfo.cs you will have to add the following to the.csproj to avoid regenerating the assemblyinfo properties which will be duplicated

  <PropertyGroup>
    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
  </PropertyGroup>

can test by running: dotnet build command
