can't use deploy

[mgigarf]

The error is following

-----> App not compatible with buildpack: https://github.com/jincod/dotnetcore-buildpack

   More info: https://devcenter.heroku.com/articles/buildpacks#detection-failure

! Push failed It's sad, that "The Buildpack will search through the repository's folders to locate a Startup.cs or Program.cs file." but my app doesn't contain any of them, and i don't know what should this files be consists of. I'm running asp.net mvc app.

I suppose it refers to .NET Framework. This buildpack support only .NET Core applications.

ASP.NET Core fundamentals https://docs.microsoft.com/en-us/aspnet/core/fundamentals/

See migration guide https://docs.microsoft.com/en-us/aspnet/core/migration/proper-to-2x/?view=aspnetcore-2.2

Hi. I recently had problems with jincod's build-pack for the same reasons, but finally got the deployment to work. Here's my crappy website...

I found the API portability analyzer helpful...

https://channel9.msdn.com/Blogs/Seth-Juarez/A-Brief-Look-at-the-NET-Portability-Analyzer

This can be used to figure out what API calls you have to stop using and find alternatives for.

Also, if you're dumb like me, you'll need to look at the properties of all your CS projects and make sure they're targeting only .net core or .net standard. If you find one targeting .net framework, then it won't work.

Also, if you don't have Startup.cs or files like that, you may need to just use the config vars like I've done as follows...

Of course, change this to suit your needs.

yeap the problem is in framework. i'll try to rewrite app. ty

[mgigarf]

So i rewrote the app, i works fine local, but when i start it on heroku it crashes. i use an xml file as db(i don't need) and heroku says there's no such file, at /app/heroku_output/filename. In my program i use static string Path = AppDomain.CurrentDomain.BaseDirectory; in order to get path for file. Also it says i have mistakes in 2 my classes and in startup.cs , but they all works fine local. If it matters, i'm creating telegram bot.

Two points

• Heroku doesn't allow to write on file system https://help.heroku.com/K1PPS2WM/why-are-my-file-uploads-missing-deleted
• your filename was not published (I suppose csproj doesn't contain something like bellow)

 <ItemGroup>
   <Content Include="filename">
     <CopyToOutputDirectory>Always</CopyToOutputDirectory>
     <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
   </Content>
 </ItemGroup>

Better to use one of Heroku Add-Ons, Heroku Postgres for instance.

I think issue can be closed now
