Build: 26107.1.d15prel

I ran into this sometimes when opening a web application:

---------------------------
Microsoft Visual Studio
---------------------------
The project system has encountered an error.

Internal error: Critical capabilities changes were detected without any change made to the project, and forces the project to be reloaded.  Potential capabilties involved: 'DotNetCoreWeb'.

A diagnostic log has been written to the following location: "C:\Users\davkean\AppData\Local\Temp\VsProjectFault_12bec44c-f230-4c32-8667-b0ff882c0c4b.failure.txt".

---------------------------
OK

The same happened to me with build: 26109.0.d15rel. Previous RCs worked well.

Repro:

If I removed the <ProjectCapability Include="EditAndContinue"/> from "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Microsoft\VisualStudio\Managed"\Microsoft.Managed.DesignTime.targets then the exception is not happening.

srivatsn commented 7 years ago

From @333fred on January 12, 2017 23:52

Fixed in #1141.

srivatsn commented 7 years ago

From @davkean on January 12, 2017 23:54

This is one is tracking DotNetWeb whcih isn't fixed. The EditAndContinue issue was fixed.

davkean commented 7 years ago

This is likely caused by a auto-load component that isn't dynamic.

Give DotNetWeb is coming from a targets file - the capability is considered dynamic, and can run into these sorts of issues.

davkean commented 7 years ago

Here's the assert under dbg CPS bits:

natemcmaster commented 7 years ago

:bell: any status update on this? I'm still seeing this in RC.3.

cc @vijayrkn @mlorbetske this is in aspnet/websdk

vijayrkn commented 7 years ago

Is the assert happening because of these Project Capability includes? https://github.com/aspnet/websdk/blob/dev/src/Web/Microsoft.NET.Sdk.Web.ProjectSystem.Targets/netstandard1.0/Microsoft.NET.Sdk.Web.ProjectSystem.targets#L28-L34

What is the right place to include Capabilities (if not from the targets)?

cc @abpiskunov @BillHiebert

abpiskunov commented 7 years ago

Hm @BillHiebert updated our autoload components to be dynamic lately and we should not have seen that again...

natemcmaster commented 7 years ago

I ran into the error with this solution: https://github.com/aspnet/SignalR/blob/7ec79bcd7c55cb2520883c08bfe2777ef9711c47/SignalR.sln

I was using VS 15.0.26127.0. It doesn't happen everytime...not sure how to make it repo consistently.

davkean commented 7 years ago

The exact error? Does it list the "Related Capabilities"?

===================

davkean commented 7 years ago

@BillHiebert @abpiskunov Are we sure we have:

1) All the auto-load components and converted to dynamic 2) No more ProjectNode COM extensions

BillHiebert commented 7 years ago

Can you try a newer build. We did an insertion on the 27th, so most likely you need a build newer than 15.0.26127.0

natemcmaster commented 7 years ago

Seems to be okay in newer builds. 👌

davkean commented 7 years ago

I'm going to close this.

xperiandri commented 7 years ago

I have the same error in VS 2017 when projects from the other folder are added to solutions
