Question

How do I recover from .net maui error NU1105 ... The property PackageVersion was expected to have a single value across all target frameworks, but instead...

Kurt K 176

This happened after I upgraded Microsoft.Maui.Controls from 9.0.70 to 9.0.81 using the NuGet Package Manager.

Full error message:

NU1105 Unable to read project information for '<MyProject>': The property PackageVersion was expected to have a single value across all target frameworks, but instead had the following values: 1.1, 1.0.0

Exiting Visual Studio, then deleting obj and bin folders, then starting Visual Studio again does not help.

Thank you.

Hello,

If you're encountering unexpected package-related errors, resetting your local environment may resolve most issues:

1. Close Visual Studio

Visual Studio often holds file handles open while running. Exiting the IDE ensures that configuration files and caches can be safely modified or deleted without interference.

2. Clear the NuGet Cache

Corrupted or outdated packages in the local cache can lead to unpredictable behavior. Run the following command to clear all local NuGet caches:

dotnet nuget locals all --clear

This forces the package manager to fetch fresh copies of required dependencies.

3. Delete Temporary Project Folders

Remove the following directories from your solution folder:

bin/

obj/

.vs/

These directories store compiled binaries, intermediate build artifacts, and IDE state. Deleting them helps eliminate stale or corrupted build data.

4. Update and Restore Workloads

Ensure all required tooling is properly installed and current:

dotnet workload update dotnet workload restore

update: brings all installed workloads to their latest compatible versions.

restore: ensures any workloads declared in your project are installed on the current machine.

I hope this helps clarify your issue. If you have any questions, feel free to reach out.

Thanks for the information, but still got the same message. More details this time:

Severity: Error (active)

Code: NU1105

Description: Unable to read project information for 'MyProject': The property PackageVersion was expected to have a single value across all target frameworks, but instead had the following values: 1.1, 1.0.0

Project: MyProject (net9.0-ios), MyProject (net9.0-maccatalyst), MyProject (net9.0-windows10.0.19041)

File: C:\Dev\MyProject\MyProject.csproj

(NOTE: In the text above, I changed the actual project name to MyProject.)

The description mentions the property PackageVersion. I cannot find that text in my .csproj file.

Note that the first time I ever (over about 5 years) had this error was yesterday when I tried to upgrade Microsoft.Maui.Controls from 9.0.70 to 9.0.81. Now I do not see any packages at all installed in my project.

Please help me with what to try next. Thank you.

Let me help you with troubleshooting:

First, open a terminal in your project directory and run:

dotnet list package --include-transitive

This will list all top-level and hidden NuGet packages used by your project.

What we're looking for are packages showing different versions across your target platforms. It might look something like this:

Project 'MyProject' has the following package references [net9.0-ios, net9.0-maccatalyst, net9.0-windows10.0.19041] Top-level Package Requested Resolved > Microsoft.Maui.Controls 9.0.81 9.0.81 Transitive Package Resolved > Some.Conflicting.Package 1.0.0 (net9.0-ios) 1.1.0 (net9.0-windows10.0.19041)

In this example, Some.Conflicting.Package is the source of the conflict.

To fix the issue, force a consistent version across all target frameworks

In your .csproj file

<ItemGroup> <PackageReference Update="Some.Conflicting.Package" Version="1.1.0" /> </ItemGroup>

If you are using Central Package Management (Directory.Packages.props)

<ItemGroup> <PackageVersion Include="Some.Conflicting.Package" Version="1.1.0" /> </ItemGroup>

After making the changes:

Delete bin and obj folders

Run dotnet restore

Then rebuild your project

To narrow down the conflict

Temporarily change your .csproj to target only one framework at a time:

<TargetFramework>net9.0-ios</TargetFramework>

Then run dotnet list package again. Repeat for each framework to isolate which one is pulling in the conflicting version.

If you'd like, you can share the output of dotnet list package/dotnet list package --include-transitive or upload your .csproj.

Thanks so much for the info! Here is what I found:

>dotnet list package --include-transitive

No assets file was found for `MyProject.csproj`. Please run restore before running this command.

>dotnet restore
Restore complete (20.6s)

Build succeeded in 20.7s

>dotnet list package --include-transitive

I did not spot any conflicts. I also did not find any instances of "1.1", only "1.1.0".

Could the error be talking about project-level versions? (Please see next comment...)

Here are the instances of ApplicationDisplayVersion, ApplicationVersion across targets:

For top-level PropertyGroup:

ApplicationDisplayVersion: 1.0 ApplicationVersion: 1

For PropertyGroup with conditions net6.0-ios, net6.0-maccatalyst, net6.0-windows10.0.19041.0 (no longer used):

ApplicationDisplayVersion: (not specified) ApplicationVersion: (not specified)

For PropertyGroup with condition net7.0-ios (no longer used):

ApplicationDisplayVersion: (not specified) ApplicationVersion: (not specified)

For PropertyGroup with conditions net8.0-ios, net8.0-maccatalyst, net8.0-windows10.0.19041 (no longer used):

ApplicationDisplayVersion: 1.1 ApplicationVersion: 1

For PropertyGroup with conditions net9.0-ios, net9.0-maccatalyst, net9.0-windows10.0.19041:

ApplicationDisplayVersion: 1.1 ApplicationVersion: 3

Within any particular .net release, I do not see any differences between targets. I also do not see any place where "1.0.0" is specified.

As you can see, we only care about .net 9 currently. What is the right way to remove the unused targets from the .csproj file?

Would you like to see the entire .csproj file?

Thank you.

Since you are using .NET 9, the older conditional property groups for .NET 6, 7, and 8 are no longer active. These blocks are safe to remove in .csproj:

 <PropertyGroup Condition="'$(TargetFramework)' == 'net6.0-ios' Or '$(TargetFramework)' == 'net6.0-maccatalyst' Or '$(TargetFramework)' == 'net6.0-windows10.0.19041.0'">  </PropertyGroup> <PropertyGroup Condition="'$(TargetFramework)' == 'net7.0-ios'">  </PropertyGroup> <PropertyGroup Condition="'$(TargetFramework)' == 'net8.0-ios' Or '$(TargetFramework)' == 'net8.0-maccatalyst' Or '$(TargetFramework)' == 'net8.0-windows10.0.19041.0'">  </PropertyGroup>

Avoiding Version Conflicts

If ApplicationVersion or ApplicationDisplayVersion is defined in multiple places (e.g., both a shared and a conditional block), MSBuild may not be able to determine a single consistent value — even if the values are currently the same.

To avoid this, choose one of the following approaches:

Global Versioning (Recommended if all platforms share the same version)

<PropertyGroup> <ApplicationDisplayVersion>1.1</ApplicationDisplayVersion> <ApplicationVersion>1</ApplicationVersion> </PropertyGroup>

Platform-Specific Versioning (Only if needed)

<PropertyGroup Condition="'$(TargetFramework)' == 'net9.0-ios' Or '$(TargetFramework)' == 'net9.0-maccatalyst' Or '$(TargetFramework)' == 'net9.0-windows10.0.19041.0'"> <ApplicationDisplayVersion>1.1</ApplicationDisplayVersion> <ApplicationVersion>1</ApplicationVersion> </PropertyGroup>

Avoid splitting this into separate blocks per platform unless absolutely necessary. MSBuild expects consistent values across all target frameworks unless you're explicitly customizing per platform.

You might need to close Visual Studio, delete .vs, bin and obj after making changes.

Platform-Specific Versions

If your app requires different versioning per platform (e.g., iOS = 1.2, Android = 1.1), it's best to set those values directly in the platform-specific manifest files:

iOS: Info.plist

Android: AndroidManifest.xml

Windows: Package.appxmanifest

Thank you for the advice. I chose the Global Versioning approach. (Made changes before starting Visual Studio.)

Then I deleted .vs, bin, obj and started Visual Studio. Unfortunately I still got the same error:

Error (active) NU1105 Unable to read project information for 'MyProject': The property PackageVersion was expected to have a single value across all target frameworks, but instead had the following values: 1.1, 1.0.0 MyProject (net9.0-ios), MyProject (net9.0-maccatalyst), MyProject (net9.0-windows10.0.19041)

So I tried your suggestion of just enabling a single TargetFramework. All three of my targets, specified separately, work fine and I can choose the "Manage NuGet Packages..." menu option to see packages.

So that gets me going again. I next will try to specify only 2 targets (ios and windows) to see if that will work. I will report back with the result.

In the meantime, I tried to do a build and experienced a separate problem:

MSBuild was unable to connect to the Mac with Address='x.x.x.x' and User='xxxxxx'. This connection is separate from Visual Studio and without it the project can't build. Please try building again or report this problem if the issue persists.

Apparently this is a current issue: https://developercommunity.visualstudio.com/t/After-Update-to-17148-Im-unable-to-bu/10934224

I will pursue that separately.

Thanks for all your help.

(Aside: The ``MSBuild was unable to connect to the Mac with Address``... error was fixed for me by the suggestion found via the link above: to install the version 9.0.204 workload.)

I tried to enable both ios and windows in TargetFrameworks. Got the same NU1105 Unable to read project information... error.

Then I tried to specify version 1.1.0 in Package.appxmanifest (Was 0.0.0; the last "0" cannot be omitted.) That still did not work.

But that's OK in my case. Thanks to your input, just specifying a single value in TargetFrameworks works fine for me.

Thank you!

Hello,

If you're encountering unexpected package-related errors, resetting your local environment may resolve most issues:

1. Close Visual Studio

Visual Studio often holds file handles open while running. Exiting the IDE ensures that configuration files and caches can be safely modified or deleted without interference.

2. Clear the NuGet Cache

Corrupted or outdated packages in the local cache can lead to unpredictable behavior. Run the following command to clear all local NuGet caches:

dotnet nuget locals all --clear

This forces the package manager to fetch fresh copies of required dependencies.

3. Delete Temporary Project Folders

Remove the following directories from your solution folder:

bin/

obj/

.vs/

These directories store compiled binaries, intermediate build artifacts, and IDE state. Deleting them helps eliminate stale or corrupted build data.

4. Update and Restore Workloads

Ensure all required tooling is properly installed and current:

dotnet workload update dotnet workload restore

update: brings all installed workloads to their latest compatible versions.

restore: ensures any workloads declared in your project are installed on the current machine.

I hope this helps clarify your issue. If you have any questions, feel free to reach out.

Thanks for the information, but still got the same message. More details this time:

Severity: Error (active)

Code: NU1105

Description: Unable to read project information for 'MyProject': The property PackageVersion was expected to have a single value across all target frameworks, but instead had the following values: 1.1, 1.0.0

Project: MyProject (net9.0-ios), MyProject (net9.0-maccatalyst), MyProject (net9.0-windows10.0.19041)

File: C:\Dev\MyProject\MyProject.csproj

(NOTE: In the text above, I changed the actual project name to MyProject.)

The description mentions the property PackageVersion. I cannot find that text in my .csproj file.

Note that the first time I ever (over about 5 years) had this error was yesterday when I tried to upgrade Microsoft.Maui.Controls from 9.0.70 to 9.0.81. Now I do not see any packages at all installed in my project.

Please help me with what to try next. Thank you.

Let me help you with troubleshooting:

First, open a terminal in your project directory and run:

dotnet list package --include-transitive

This will list all top-level and hidden NuGet packages used by your project.

What we're looking for are packages showing different versions across your target platforms. It might look something like this:

Project 'MyProject' has the following package references [net9.0-ios, net9.0-maccatalyst, net9.0-windows10.0.19041] Top-level Package Requested Resolved > Microsoft.Maui.Controls 9.0.81 9.0.81 Transitive Package Resolved > Some.Conflicting.Package 1.0.0 (net9.0-ios) 1.1.0 (net9.0-windows10.0.19041)

In this example, Some.Conflicting.Package is the source of the conflict.

To fix the issue, force a consistent version across all target frameworks

In your .csproj file

<ItemGroup> <PackageReference Update="Some.Conflicting.Package" Version="1.1.0" /> </ItemGroup>

If you are using Central Package Management (Directory.Packages.props)

<ItemGroup> <PackageVersion Include="Some.Conflicting.Package" Version="1.1.0" /> </ItemGroup>

After making the changes:

Delete bin and obj folders

Run dotnet restore

Then rebuild your project

To narrow down the conflict

Temporarily change your .csproj to target only one framework at a time:

<TargetFramework>net9.0-ios</TargetFramework>

Then run dotnet list package again. Repeat for each framework to isolate which one is pulling in the conflicting version.

If you'd like, you can share the output of dotnet list package/dotnet list package --include-transitive or upload your .csproj.

Thank you for following up, Michael. Yes, all is working for me. Specifying a single value in TargetFrameworks at a time continues to work fine.

Answer 1

Hello @Kurt K,

I really appreciate your engagement and patience in troubleshooting the issue. To assist you and others who may encounter a similar issue, I have summarized the problem and its resolution below for clarity.

Problem Summary

The issue arose due to ApplicationVersion and ApplicationDisplayVersion being defined in multiple locations within the project, leading to conflicts during the build process, particularly in multi-targeted .NET projects.

Resolution

To resolve this issue, I recommend avoiding multi-targeting by building one target framework at a time. Additionally, ensure that version properties are defined consistently and appropriately for your project’s requirements.

Specify a Single Target Framework in the .csproj File
Modify your .csproj file to target a single framework at a time, rather than using multi-targeting. Update the TargetFrameworks property to a single TargetFramework as shown below:
```
   
   <TargetFrameworks>net9.0-ios;net9.0-maccatalyst;net9.0-windows10.0.19041</TargetFrameworks>
 
   
   <TargetFramework>net9.0-ios</TargetFramework>
   
   <TargetFramework>net9.0-maccatalyst</TargetFramework>
   
   <TargetFramework>net9.0-windows10.0.19041</TargetFramework>
```
Note that you should choose one of the target frameworks based on your current development focus. If you need to build for multiple platforms, consider doing so in separate builds rather than in a single multi-targeted build.
Define Version Properties Consistently If all platforms share the same version, define ApplicationDisplayVersion and ApplicationVersion only once in the .csproj file, outside of any platform-specific conditional blocks:
```
   <PropertyGroup>
     <ApplicationDisplayVersion>1.1</ApplicationDisplayVersion>
     <ApplicationVersion>1</ApplicationVersion>
   </PropertyGroup>
```
Handle Platform-Specific Versioning If your application requires different versions for each platform (e.g., iOS = 1.2, Android = 1.1), set these values directly in the respective platform-specific manifest files:
- iOS: Info.plist
- Android: AndroidManifest.xml
- Windows: Package.appxmanifest
Clean and Rebuild the Project
After making these changes, clean your project to remove any cached build artifacts and then rebuild to ensure the new settings are applied correctly.

Additional Notes

Ensure no duplicate definitions of ApplicationVersion or ApplicationDisplayVersion exist in your .csproj file or other configuration files, as this can lead to conflicts.
For further details on resolving NuGet-related issues, refer to the official documentation: NuGet Error NU1105.

Again, thank you for your patience and collaboration in resolving this issue. If you have any further questions or need additional assistance, please feel free to reach out. I really appreciate your feedback.
