As for me  I realized there was another web project in the solution that my VS2017 was loading fine  so I copied over the ProjectTypeGuids element of it over to the project that wasn t loading  Its diff was   -     lt ProjectTypeGuids gt  E3E379DF-F4C6-4180-9B81-6769533ABE47   349c5851-65df-11da-9384-00065b846f21   fae04ec0-301f-11d3-bf4b-00c04f79efbc  lt  ProjectTypeGuids gt        lt ProjectTypeGuids gt  349c5851-65df-11da-9384-00065b846f21   fae04ec0-301f-11d3-bf4b-00c04f79efbc  lt  ProjectTypeGuids gt    After this  it loads  Don t ask me why

If you are getting the same error for a project which is actually an extension   vsix   installing Microsoft Visual Studio 2012 SDK does the trick

In my case it was an incompatible Project Type  Editing project file and removing ProjectTypeGuids node resolved the issue of loading the project  I had already re-targeted the framework version as advised here    Probably the project type is not supported in the  most likely  NEW version of VS  so you will have to adjust  update  the code to work properly  if possible   but at least you can see the content through VS

For me  I got this same error in VS 2015 and just installed the VS 2015 update 1  though from another answer  VS is actually up to Update 3  now  after which  they got the error and had to install  NET Core    Had issues when it hit certain packages  like the Windows SDK ones  and had to point the installer back at the paths in my original CD  and for some  even that didn t work and had to skip them and re-download from an internet-connected computer  transfer them over  and run them later manually  computer was not connected to the internet to be able to download updated versions of the packages   but after doing all that and doing a reboot  the error was gone and my project loaded fine

I had this error and found it was due to the presence an  Import  XML tag inside the  csproj user file    Once I removed it  Visual Studio could open the project again

What most people forget it is that the files of visual studio are just text files  that have some peculiars configurations that will show to the program how to open it  that is  we can change this because it s just a text in some file in there in your project folders   Well  knowing this  what we have to do is very simple   The first step is knowing what kind of project it is this project that stay unload   for example  Class Library   The Second step is create a new one  Class Library  because you know that your visual studio will create a version supported by himself  Unload this one and click in  Edit csproj    It s in this file that we can found the configuration that tell to VS how this proj will be loaded and his name is ProjectGuid  this serial number has a variation according the type and version of project   Now  look at your  ok project   copy the  ProjectGuid  TAG  paste on csproj that unloaded  and pay attention to the little differences and make this files almost equals  except for the tags ItemGroup that represent the references of the project   Doing that  save all files and close your VS and open again  now your project should load normally   I hope that this informations help somebody to understand a bit more how the VS works and help solve the problems when necessary

I had this issue and after hours of uninstalling and reinstalling I found out the issue in my instance   The reason why I got this was down to the fact that I didn t have the correct extension   In my case the ASP net project  my startup  was the incompatible project and this was because I didn t have the following    Microsoft ASP NET and Web Tools Micrsoft ASP NET Web Frameworks and Tools   It was a simple case of going into extensions and updates under the Tools menu

VS 2012 has different project type support based on what you install at setup time and which edition you have  Certain options are available  e g  web development tools  database development tools  etc  So if you re trying to open a web project but the web development tools weren t installed  it complains with this message   This can happen if you create the project on another machine and try to open it on a new one  I figured it out trying to open an MVC project after I accidentally uninstalled the web tools

I just got the same error message with a couple projects after installing Visual Studio 2015 Update 3  For me  the solution was to install  NET Core

If the message      This project is incompatible with the current version of Visual Studio   is due to an attempt to open a project targeting  Net 4 5  then the  solution  or workaround is to edit the  csproj file and change the TargetFrameworkVersion from  v4 5  to  v4 0   That at least allows the project to be loaded  although it may result in compiler errors if the program is dependent on 4 5 features
