Answer 1

I had the same problem using .Net Standard 2.1, and I solved it for myself by cleaning the solution and then rebuilding it.

Answer 2

Just moved my projects to a new machine (copying, not pulling from GIT) and started getting this. Deleting the bin and obj folders in each project solved this issue.

Answer 3

Your combination of Mono MSBuild and .NET Core SDK is incompatible because they use different versions of the internal NuGet library. To resolve this problem, you can:
Downgrade .NET Core SDK to 2.1.5xx or 2.2.1xx (for example, 2.1.505 or 2.2.108)
Upgrade Mono to 6.0
You can find a detailed explanation of this problem and possible solutions here: https://rider-support.jetbrains.com/hc/en-us/articles/360004180039

Answer 4

This appears to be a known issue.
The only fix at this stage seems to be to downgrade to .NET Core v2.2.105.
To downgrade:
Uninstall the latest .NET Core version (v2.2.2+).
Download and install v2.2.105.

Answer 5

Run the following CMD in the *.sln folder. This will delete all your OBJ and BIN folders automatically. And your issue will be solved.
FOR /d /r . %%d in (bin,obj) DO ( IF EXIST "%%d" ( ECHO %%d | FIND /I "\node_modules\" > Nul && ( ECHO.Skipping: %%d ) || ( ECHO.Deleting: %%d rd /s/q "%%d" )))

Answer 6

I had the same problem in migration from .Net Framework 4.5 to .NET 6.0 (with the 70 project).
All of the above answers are correct, but they were not enough for my problem.
I use this answer:
Deleting the bin and obj and .vs folders then Clean Solution and
Rebuild Solution
it's working in Build Mode, not Rebuild. And the problem remained.
I update the Version of SDK , but not enough and I have the problem.
I realized this:
duplicate property (or variables) with the same name (or similar Name) in derived classes.
It was a good solution and a few problems were solved.
finally (after the 3 days), The biggest problem I noticed was that I had Loop References.
I fixed The Loop References in projects and the error is solved.

Answer 7

Change the name of the file. For instance, Add prefix _ or #; so, it cannot be used.
Restart Visual Studio, then try to build. If still problem is there, needs to restart the machine.

Answer 8

I had this error happen and the slove for me was correcting the Package version number in .csproj file .
<Version>2.0.7.</Version> <!--casued the error-->
<Version>2.0.7</Version> <!--this fixed the error-->
Removing the trailing '.' fixed this for me.

Answer 9

I had .net standard project built on .net standard 2.0. Yesterday I updated my Visual Studio 2019 to 16.3.0 to leverage .Net Core 3.0. But all of sudden build of project targeting on standard 2.0 started throwing "GenerateDepsFile" task failed unexpectedly error.
I was able to resolve this issue by changing the target framework to 2.1.
