Visual studio 2017 Update 3 - The SDK 'Microsoft.NET.Sdk.Web' specified could not be found

Question

Error:

C:\\WebApp\\WebApp.csproj : error : The SDK \'Microsoft.NET.Sdk.Web\' specified could not be found. C:\\WebApp\\WebApp.csproj

Answer 1

I was running into an issue where creating a new ASP.NET Core 2.0 project was giving me an error The SDK 'Microsoft.Net.Sdk.Web' specified could not be found, and leaving me unable to open the project in Visual Studio. The problem was the project was created in a folder that contained a global.json file, tying the SDK version to 1.0.0.

Deleting the global.json, or updating it to 2.0.0, fixed the issue. Be sure to check parent folders too - if any parent folder contains a global.json, the SDK version specified in the "closest" folder will be used.
