I will try to explain “How to write .net core web api via MongoDB” in this post. Firstly, I should install MongoDB to my computer. Let’s get start. I used this link for download. Example screenshot is as follows.
After downloaded application, Let’s start to install it. The screenshots are as follows.
You can cancel MongoDB Compass. I didn’t install it.
After installation, I added new value in environment variables. This is for command prompt. I used mongoDB setup location in this step. My one is C:\Program Files\MongoDB\Server\4.2\bin If you want, you can skip this step.
I added two times. First one User variables for Your Username area and second one is system variables area. You should restart your computer after this step.

That examples are enough for now. Maybe we can check all commands in another article. Now, let’s get start to web api.
I created and opened my project. After created project, I added mongoDB driver in my project. I used command for this as follows.
dotnet add package MongoDB.Driver –version 2.9.2
You can see this package in your .csproj file.
I started from model folder for development. Firstly, I created base model file. I added Id field because mongoDB is using Id field in collections. I created base model file for this. The screenshot is as follows.
After this file, I created an example model for my web api methods.
Now, I created a base repository for my models. I will use this with my model repository.
Example model repository is as follows.
I added connection string property in appconfig.json file. I will use this in startup.cs file.
Startup.cs is as follows.
Example methods are as follows.
Now, I can see my database on command prompt.
You can download my example project in this link.
