Aspire SDK fails build when using exact versions of dependency Aspire.Hosting.AppHost

[dmitrynovik]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

Our company build requires that all external packages are pinned to a specific versions e.g. [9.0.0]. It fails the build otherwise.

The Aspire SDK does not honour the square brackets.
The following package reference (note the brackets):

  <ItemGroup>
    <PackageReference Include="Aspire.Hosting.AppHost" Version="[9.0.0]"  />
  </ItemGroup>

Produces the compile error

error MSB4184: The expression "[MSBuild]::VersionLessThan([9.0.0], 8.2.0)" cannot be evaluated. Version string was not in a correct format

Expected Behavior

The pinned version should work - strip [] from the SemVer.

Steps To Reproduce

Square-bracket the package version of Aspire.Hosting.AppHost e.g.:

<PackageReference Include="Aspire.Hosting.AppHost" Version="[9.0.0]"  />

This is a dupe of #7102

Good catch! Not exactly a dupe, but they both surely have the same root cause and should be fixed by the same change. I'll add this to the 9.1 milestone to tackle along with #7102.
