[aspnetcore] .csproj doesn't load in Visual Studio 2017

[TomSelleck101]

Description

The generated aspnetcore project won't open in Visual Studio 2017 (tested with version 15.4.1).

Swagger-codegen version

Version 2.3.1 - hosted on editor.swagger.io

Swagger declaration file content or url

gist here

Command line used for generation

editor.swagger.io

Steps to reproduce

1. Paste contents of gist into http://editor.swagger.io (Not https as the content can't be downloaded over https :/ )
2. Click Generate Server
3. Click aspnetcore
4. Extract the folder from the downloaded .zip
5. Open the .sln file to open with Visual Studio 2017
6. The project says IO.Swagger (load failed) in the solution explorer
7. Attempting to right click and reloading the project brings an error which says: The operation could not be completed. Unspecified error.

I too am experiencing this issue, vanilla code generated by Swagger UI won't load VS 2017 (15.6.4)

Just happened to me as well. VS 2017 (15.6.5)

Looks to be the same thing as #7614 - removing and re-adding the .csproj file resolves this.

@djmitchella That solved it for me. Thanks!

[antti88]

That worked for me too! Thanks!

Interesting thought that you can still open the solution without any issues on Mac Visual Studio but not on Windows.

The project also loads without a problem in Visual Studio Code.
Upon removing and re-adding, two changes are made to the .sln file:

1. The project GUID is changed.
2. This added to the end of the file:
   GlobalSection(ExtensibilityGlobals) = postSolution
   SolutionGuid = {some GUID}
   EndGlobalSection

The generated project path is missing backslashes. Looks like this is the case for csharp too.

Project("{8BB2217D-0F2D-49D1-97BC-3654ED321F3B}") = "IO.Swagger", "srcIO.SwaggerIO.Swagger.csproj", "{C90F1986-9E16-4F6B-86EE-9E22593A9ED9}"

I'm guessing this has to do with how Mustache handles backslashes?

Here what worked for me
I created a new blank solution in Visual Studio
I added a new .Net Core API project
Then added an existing project and selected my generated swagger project
Then made that project start up project.
Rebuild solution then ran fine

I'm having the same issue, but I can't even open the csproj on its own.

When I first try to open the project I get

If I try to reload then I get:

I've just removed the project from the solution and re-added it. It worked.
