Hello, qxWork, you wrote: W> What exactly does not suffice? Multifile? Under the signature of a call of a nonexistent method, it is necessary to deduce types of arguments and to generate some types and methods, let even in the same file. As far as I understand, it can achieve, using extensions for , but them, besides, it is necessary to write. W> and it is possible more in detail about a hell and ? Certainly. We open docks. We rejoice to simplicity of the decision. We transit under the link and we fall out in a precipitate as realization of comes that to us suggest to solve Einstein's riddle. Further this suspicion only gets stronger. But it is good, we adult experienced programmers, are able in manuals and to carry out step by step instructions. We enter: PM> Install-Package JetBrains. ReSharper. SDK-Version 2017.2.1 we Receive: Install-Package: Unable to find version ' 2017.2.1 ' of package ' JetBrains. ReSharper. SDK '. Here it is turn! All right, to whom does not happen. We climb on a site for version SDK... 404 Not Found (it is at the moment corrected, I lucky) Tightening a packet locally, we try to install. Attempting to resolve dependency ' xunit.abstractions (= 2.0.1) '. The ' xunit.abstractions 2.0.1 ' package requires NuGet client version ' 2.12 ' or above, but the current NuGet version is ' 2.8.60610.756 '. Yes well yours ! , it is guilty, we put fresh updates. We repeat operation. It was installed! Ur! Well, now that we write the first plug-in and we begin to live!. Stop. What for.nuspec? I simply want to push F5 and to see Hello world in a menu R#! Hyperlinks are not present. Search in the documentation, naturally, does not give results (it is search!) . Okej, we experienced programmers also are able to use Google. About my God, how many letters! And all about the old version... Attempt number two. . It seems, it that is necessary for me. But stop, and what I read before? differ from plug-ins? And if it is different pieces, where the description.nuspec for ?! What happens?! And all this time in a head is twisted thought, what about five years ago there were templates of projects in which it is possible to thrust everything, including dependences on NuGet-packages so what devil it is necessary to do all it is hands?! Somehow so.
