[Fixed] IServiceCollection doesn’t contain definition of AddSwaggerGen
In this post, I will show how did I fix the issue of adding Swagger in the .net core.
I was trying to install the Swagger in my first .net core project. I did it very easily in ASP.Net MVC very easily but getting issues with .net core.
I installed the NuGet package but was getting still an issue. I found it’s due to I installed the wrong package. After installing the correct one I got it working.
I hope it will save your time too.
