Solidity integration with Visual Studio

Artykuł
04/01/2016

Getting Started with Solidity

Yesterday we were proud to announce the integration of Solidity and the Smart Contracts that work with Ethereum blockchains into Visual Studio. This exists as an extension that is available here. This extension was designed to lower the bar to working with blockchains and make this a seemless process from inside the world class IDE.

The extension is free, and we have put together some steps to further help you get started using this.

Prerequisites

To get started you will need to be using Visual Studio 2015 Community, Professional, or Enterprise edition. You will also need to download the Solidity extension from the Visual Studio Marketplace. You can download that here. After installing the extension, you will need to restart Visual Studio. Also, nodejs will need to be installed to allow local deployments for development. This can be downloaded here. (download the latest LTS version)

Create your first Decentralized Application

After the extension has been installed, next you can create a decentralized application that will be used to author, compile and deploy smart contracts.

1. From the File menu, click new Project.

2. In the New Project dialog box, click on Solidity under Installed Templates, and then select DecentralizedApplication. Name the application, MyDecentralizedApp, and then click OK.

3. Next you will see a few things happened. A README document was opened in the Visual Studio main window and the project was setup with some folder and sample files. The README explains how to setup a local keyserver in order to deploy smart contracts to a development blockchain instance.

a. First download and install the latest version of bloc from Consensys. To do this, open a cmd prompt, navigate to a directly where you would like to install the keyserver and run the following command: npm install blockapps-bloc -g

b. Next create the instance of bloc from the core by running the command: bloc init.This will prompt you for some values that will be used the instance. Enter a name of your choice, and user name, and accept the default for the apiUrl. This is the ethereum node that will hold the actual blocks that your account/contracts will be deployed to.

c. Now change to that directory and install the required node packages by running the following command: cd <appname> && npm install

d. Finally you are ready to start the bloc instance by running the following command: bloc start

4. Now we have a keyserver running. This local keyserver will run on port 8000 by default. The Visual Studio extension is configured to use this server by default, with a user named: testuser and a password: testing. You can view and edit these changes by running the following:

a. Right click the project in solution explorer.

b. The dialog here shows the configuration values that are set by default, and can be adjusted if needed. (they will not need to be adjusted in most cases)

5. At this point we have a keyserver running locally, now we have an endpoint that we can deploy our smart contracts to (as well as create new users). So now we can get started with development of smart contracts.

Working with Smart Contracts (authoring, compiling, deploying)

Now that the foundation is place, we can take a look at working with Smart Contracts. By default a folder named samples will be created with some sample contracts already included. When you are just getting started with Solidity, these are a great source of reference.

To get started, we can use the Payout.sol smart contract. First, we can examine the contract in the Visual Studio code window. When we are satisified with what we have authored, we can then compile this contract. This compiliation will take place on the local machine. The output from the compliation will be in the output window of Visual Studio,

Compilation

1. Compile the smart contract

2. The output for the compilation is found in the output window. If you don't see the output window in the lower part of your screen you can open from the View -> Output menu (or Ctrl + W, O). If there any errors with the compilation, it will be shown in the output window as well.

Deployment

The deployment is nearly as simple as the compilation. The deployment will send the smart contract to your local keyserver which will communicate with the underlying blockchain. What is actually happening is this.

1. First, VS will use the project properties (shown earlier) to determine the bloc server to communicate with (url).

2. Next VS will call this server, asking if the user in the project properties, exists.

a. If it does exist, the address of the user will be returned to Visual Studio.

b. If it doesn't exist, a new user will be created, and that address will be returned to Visual Studio.

3. Next, VS will get the source for the contract, along with the address of the user and post this to the bloc server.

4. Finally, your default browser will be opened to a dynamically created html page of the smart contract that was deployed.

5. When the browser opens, you can enter the password for the bloc server (default is testing).

6. You can then exercise the contract. For example, you can send in a value in Ether by post 1 to the setup box.

Next Steps

At this point, congratulations, you have now entered the blockchain universe! I will be posting some more tutorials to expand on this.

      Yes, the issue is after you run bloc init, then go into the directory cd , the bower.json has the application name parameter set to {{appname}}. Just change this to (no brackets or braces), and then npm install, and you should be in good shape. The core issue was caused by an update to the npm package, we will push a change to fix this asap, but you can use this as a workaround right now. Thanks!

        The npm package is updated now. Current version that is now 0.9.11, which I just tested and it is working fine. Just run a npm install blockapps-bloc -g to update your global package with the fix.

At step 5, enter password "testing" and then click Submit, after which nothing happens i.e. password prompt remains and no error appears.

  I believe the html that is generated here has some issues with IE11. I have seen the same issues when using IE. Alternative to use Edge, Chrome or FF. It uses your default browser, so if you don't want to change that, just copy+paste the url to one of the other browsers and it should render and function normally.Much appreciate the feedback, this is really early days for these extensions, so we are working hard to improve the experience and this feedback helps!

I've tried your steps several times in Visual Studio 2015 and whenever I attempt to deploy the smart contract, I keep getting "object reference not set to an instance of an object". Any ideas?

Sounds like the keyserver is not running. Can you check if its listening (default): http://localhost:8000 (step 4 in blog post). You can actually browse to this url, and you should get a response.
- Anonymous
  April 26, 2016
  The URL is not working. I did noticed that when I typed in "bloc start" in cmd window, I didn't get a response of "bloc is listening on http:......". Do you know how I can resolve this? Not that is matters, but I am running the VS project as an administrator and it is VS 2015 Enterprise Upgrade 2. Thanks again!

    Ok, then the node app is not running. Couple things to check: Is there a npm-debug.log file the folder the bloc init created? If so need to resolve any issues there with creating your keyserver instance You can try starting with this as well: node app.js (run this from within the folder above)Just as an FYI, this model where you run a local server is just an interim step, we are working to remove this going forward and make this process easier. New build will be out very soon with a few other features as well.

        Cale, thanks for leading me in the right direction. Running netstat, I figured out another service was already listening on port 8000 and once I changed it to a different port in the app.js and VS project properties, everything started to work!! Thanks!!

I can't seem to compile any contracts that I create. I receive: "Error: Expected import directive or contract definition." Sample contracts compile fine. My contract is in the main project directory, Any ideas?

  Checking into this. We have another release imminent, which will add more options on the items to add to the project. One option to keep you moving would be to copy an sample contract (e.g. Payout.sol) to your folder and then modify. Not great, but will keep you moving. Incidentally, we are also enabling better file / folder support in the new build.Thanks.

    Thanks. I tried moving the existing contracts, but they fail once outside the samples dir as well. And new contracts created and manually moved into the samples dir fails as well. So, I've just taken to editing the 3 provided samples, which I can compile and deploy.

Maybe just add after point 3.c to run "bloc genkey" before "bloc start". Everything else is perfectly explained.

  Hi Nelson, We have been heads down on updates which are releasing tonight. I would ask if you can reinstall the latest blockapps-bloc (globally) and run the updated extension. Also, make sure git is in your path. You can verify this by opening a new command windows and typing git to see if you get git help. Thanks and apologies on the delay!

How to know which ethereum address use for deploy contract?

  September 21, 2016
  If you are using bloc its pretty easy.Then you can do a few things. You can hit it from bloc, just do a bloc start and then open your browser and hit http://localhost:8000/contractsYou can then exercise it there in your browser to test it out.

  I wonder if a glitch we had with the public strato instance (strato-dev4) caused this issue for you. Could you try this? Go into your bloc instance (the folder created by bloc init) and into the app folder. Delete the meta and users folder if they exist and retry. Apologies for the late reply. Let me know if this doesn't resolve your issue.

I am running. VS as administrator, host 8000 started but user check fails. User name is testuser, password testing.

  Can you check in the folder for your bloc (the one that gets created when you run bloc init). Check under the app folder. If there is a subdirectory for users in there, delete it. The restart bloc (bloc start), and finally run the deployment from VS.Hope this helps!

Many thanks for this tutorial. I get as far as step 5 in deployment then when I enter the password I get a page not found error. At the keyserver I see 'GET /login?password=testing 404'. Are you able to help please?
- Anonymous
  November 23, 2016
  Ok, lets check something. If bloc running, navigate to http://localhost:8000/users. If you see [] then no users are created, which is fine. If you see [testuser], then the test user was created. The password is testing. You can then open Visual Studio, create a new Smart Contract project type, then navigate a sample smart contract and right click/deploy smart contract. When the browser window opens use testing as password. You should be able to see in the background the user that is being used, which should be testuser.Let me know if this does not work for you.Thanks!

    Thanks for your swift response. If I go to http://localhost:8000/users I see ["testuser"]. However when I choose Deploy Smart Contract in Visual Studio and enter the password in the resulting browser I then get the 404.

  Hi Sweta,Apologies on my extreme delay getting back to you. The problem is caused by the fact that we use (http://strato-dev4.blockapps.net) by default and this server is having some stability issues. We are looking at standing up something more stable, but in the interium the workaround would be to run your own instance of strato in Azure. There is a small cost associated, but they do offer 30 days for free or you can use the TestDrive option for 2 hours of free use. You will need to update your bloc configuration to use the new endpoint.We will update the blog when a new public instance if ready.Thanks for your patience!Cale

  Hi Judy,Sorry for the lag in my response. The issue is caused by stability issues with (http://strato-dev4.blockapps.net). We are looking to build something more stable here, but this is not ready yet. The alternative would be to create a new instance of Strato in Azure. There is a small cost here, but they do offer the first 30 days for free, you just pay for the VM or you can us TestDrive for 2 hours of free use. I will update the blog when we have a new public instance for use.Thanks for you patience!Cale
